+<!-- # Generated by synthtool. DO NOT EDIT! !-->
+# Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of
+experience, education, socio-economic status, nationality, personal appearance,
+race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+*   Using welcoming and inclusive language
+*   Being respectful of differing viewpoints and experiences
+*   Gracefully accepting constructive criticism
+*   Focusing on what is best for the community
+*   Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+*   The use of sexualized language or imagery and unwelcome sexual attention or
+    advances
+*   Trolling, insulting/derogatory comments, and personal or political attacks
+*   Public or private harassment
+*   Publishing others' private information, such as a physical or electronic
+    address, without explicit permission
+*   Other conduct which could reasonably be considered inappropriate in a
+    professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, or to ban temporarily or permanently any
+contributor for other behaviors that they deem inappropriate, threatening,
+offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+This Code of Conduct also applies outside the project spaces when the Project
+Steward has a reasonable belief that an individual's behavior may have a
+negative impact on the project or its community.
+
+## Conflict Resolution
+
+We do not believe that all conflict is bad; healthy debate and disagreement
+often yield positive results. However, it is never okay to be disrespectful or
+to engage in behavior that violates the project’s code of conduct.
+
+If you see someone violating the code of conduct, you are encouraged to address
+the behavior directly with those involved. Many issues can be resolved quickly
+and easily, and this gives people more control over the outcome of their
+dispute. If you are unable to resolve the matter for any reason, or if the
+behavior is threatening or harassing, report it. We are dedicated to providing
+an environment where participants feel welcome and safe.
+
+Reports should be directed to *googleapis-stewards@google.com*, the
+Project Steward(s) for *Google Cloud Client Libraries*. It is the Project Steward’s duty to
+receive and address reported violations of the code of conduct. They will then
+work with a committee consisting of representatives from the Open Source
+Programs Office and the Google Open Source Strategy team. If for any reason you
+are uncomfortable reaching out to the Project Steward, please email
+opensource@google.com.
+
+We will investigate every complaint, but you may not receive a direct response.
+We will use our discretion in determining when and how to follow up on reported
+incidents, which may range from not taking action to permanent expulsion from
+the project and project-sponsored spaces. We will notify the accused of the
+report and provide them an opportunity to discuss it before any action is taken.
+The identity of the reporter will be omitted from the details of the report
+supplied to the accused. In potentially harmful situations, such as ongoing
+harassment or threats to anyone's safety, we may take action without notice.
+
+## Attribution
+
+This Code of Conduct is adapted from the Contributor Covenant, version 1.4,
+available at
+https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+# How to Contribute
+
+We'd love to accept your patches and contributions to this project. There are
+just a few small guidelines you need to follow.
+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution;
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to <https://cla.developers.google.com/> to see
+your current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## Code reviews
+
+All submissions, including submissions by project members, require review. We
+use GitHub pull requests for this purpose. Consult
+[GitHub Help](https://help.github.com/articles/about-pull-requests/) for more
+information on using pull requests.
+
+## Community Guidelines
+
+This project follows
+[Google's Open Source Community Guidelines](https://opensource.google.com/conduct/).
+
+## Building the project
+
+To build, package, and run all unit tests run the command
+
+```
+mvn clean verify
+```
+
+### Running Integration tests
+
+To include integration tests when building the project, you need access to
+a GCP Project with a valid service account. 
+
+For instructions on how to generate a service account and corresponding
+credentials JSON see: [Creating a Service Account][1].
+
+Then run the following to build, package, run all unit tests and run all
+integration tests.
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
+mvn -Penable-integration-tests clean verify
+```
+
+## Code Samples
+
+Code Samples must be bundled in separate Maven modules, and guarded by a
+Maven profile with the name `enable-samples`.
+
+The samples must be separate from the primary project for a few reasons:
+1. Primary projects have a minimum Java version of Java 7 whereas samples have
+   a minimum Java version of Java 8. Due to this we need the ability to
+   selectively exclude samples from a build run.
+2. Many code samples depend on external GCP services and need
+   credentials to access the service.
+3. Code samples are not released as Maven artifacts and must be excluded from 
+   release builds.
+   
+### Building
+
+```bash
+mvn -Penable-samples clean verify
+```
+
+Some samples require access to GCP services and require a service account:
+
+```bash
+export GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/account.json
+mvn -Penable-samples clean verify
+```
+
+### Profile Config
+
+1. To add samples in a profile to your Maven project, add the following to your
+`pom.xml`
+
+    ```xml
+    <project>
+      [...]
+      <profiles>
+        <profile>
+          <id>enable-samples</id>
+          <modules>
+            <module>sample</module>
+          </modules>
+        </profile>
+      </profiles>
+      [...]
+    </project>
+    ```
+
+2. [Activate](#profile-activation) the profile.
+3. Define your samples in a normal Maven project in the `samples/` directory.
+
+### Code Formatting
+
+Code in this repo is formatted with
+[google-java-format](https://github.com/google/google-java-format).
+To run formatting on your project, you can run:
+```
+mvn com.coveo:fmt-maven-plugin:format
+```
+
+### Profile Activation
+
+To include code samples when building and testing the project, enable the 
+`enable-samples` Maven profile.
+
+#### Command line
+
+To activate the Maven profile on the command line add `-Penable-samples` to your
+Maven command.
+
+#### Maven `settings.xml`
+
+To activate the Maven profile in your `~/.m2/settings.xml` add an entry of
+`enable-samples` following the instructions in [Active Profiles][2].
+
+This method has the benefit of applying to all projects you build (and is
+respected by IntelliJ IDEA) and is recommended if you are going to be
+contributing samples to several projects.
+
+#### IntelliJ IDEA
+
+To activate the Maven Profile inside IntelliJ IDEA, follow the instructions in
+[Activate Maven profiles][3] to activate `enable-samples`.

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# Google Channel Services Client for Java
+
+Java idiomatic client for [Channel Services][product-docs].
+
+
+- [Product Documentation][product-docs]
+
+## Authentication
+
+See the [Authentication][authentication] section in the base directory's README.
+
+### Prerequisites
+
+You will need a [Google Cloud Platform Console][developer-console] project with the Channel Services enabled.
+You will need to [enable billing][enable-billing] to use Google Channel Services.
+[Follow these instructions][create-project] to get your project set up. You will also need to set up the local development environment by
+[installing the Google Cloud SDK][cloud-sdk] and running the following commands in command line:
+`gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.
+
+### Installation and setup
+
+You'll need to obtain the `google-cloud-channel` library.  See the Quickstart section
+to add `google-cloud-channel` as a dependency in your code.
+
+## About Channel Services
+
+With [Channel Services][product-docs], Google Cloud partners and resellers have 
+a single unified resale platform, with a unified resale catalog, customer management,
+order management, billing management, policy and authorization management, and cost 
+management.
+
+## Troubleshooting
+
+To get help, follow the instructions in the [shared Troubleshooting document][troubleshooting].
+
+## Transport
+
+Channel Services uses gRPC for the transport layer.
+
+## Java Versions
+
+Java 7 or above is required for using this client.
+
+## Versioning
+
+
+This library follows [Semantic Versioning](http://semver.org/).
+
+
+It is currently in major version zero (``0.y.z``), which means that anything may change at any time
+and the public API should not be considered stable.
+
+## Contributing
+
+
+Contributions to this library are always welcome and highly encouraged.
+
+See [CONTRIBUTING][contributing] for more information how to get started.
+
+Please note that this project is released with a Contributor Code of Conduct. By participating in

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Service Description: CloudChannelService enables Google cloud resellers and distributors to
+ * manage their customers, channel partners, entitlements and reports.
+ *
+ * <p>Using this service: 1. Resellers or distributors can manage a customer entity. 2. Distributors
+ * can register an authorized reseller in their channel and then enable delegated admin access for
+ * the reseller. 3. Resellers or distributors can manage entitlements for their customers.
+ *
+ * <p>The service primarily exposes the following resources: -
+ * [Customer][google.cloud.channel.v1.Customer]s: A Customer represents an entity managed by a
+ * reseller or distributor. A customer typically represents an enterprise. In an n-tier resale
+ * channel hierarchy, customers are generally represented as leaf nodes. Customers primarily have an
+ * Entitlement sub-resource discussed below.
+ *
+ * <p>- [Entitlement][google.cloud.channel.v1.Entitlement]s: An Entitlement represents an entity
+ * which provides a customer means to start using a service. Entitlements are created or updated as
+ * a result of a successful fulfillment.
+ *
+ * <p>- [ChannelPartnerLink][google.cloud.channel.v1.ChannelPartnerLink]s: A ChannelPartnerLink is
+ * an entity that identifies links between distributors and their indirect resellers in a channel.
+ *
+ * <p>This class provides the ability to make remote calls to the backing service through method
+ * calls that map to API methods. Sample code to get started:
+ *
+ * <p>Note: close() needs to be called on the CloudChannelServiceClient object to clean up resources
+ * such as threads. In the example above, try-with-resources is used, which automatically calls
+ * close().
+ *
+ * <p>The surface of this class includes several types of Java methods for each of the API's
+ * methods:
+ *
+ * <ol>
+ *   <li>A "flattened" method. With this type of method, the fields of the request type have been
+ *       converted into function parameters. It may be the case that not all fields are available as
+ *       parameters, and not every API method will have a flattened method entry point.
+ *   <li>A "request object" method. This type of method only takes one parameter, a request object,
+ *       which must be constructed before the call. Not every API method will have a request object
+ *       method.
+ *   <li>A "callable" method. This type of method takes no parameters and returns an immutable API
+ *       callable object, which can be used to initiate calls to the service.
+ * </ol>
+ *
+ * <p>See the individual methods for example code.
+ *
+ * <p>Many parameters require resource names to be formatted in a particular way. To assist with
+ * these names, this class includes a format method for each type of name, and additionally a parse
+ * method to extract the individual identifiers contained within names that are returned.
+ *
+ * <p>This class can be customized by passing in a custom instance of CloudChannelServiceSettings to
+ * create(). For example:
+ *
+ * <p>To customize credentials:
+ *
+ * <pre>{@code
+ * CloudChannelServiceSettings cloudChannelServiceSettings =
+ *     CloudChannelServiceSettings.newBuilder()
+ *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
+ *         .build();
+ * CloudChannelServiceClient cloudChannelServiceClient =
+ *     CloudChannelServiceClient.create(cloudChannelServiceSettings);
+ * }</pre>
+ *
+ * <p>To customize the endpoint:
+ *
+ * <pre>{@code
+ * CloudChannelServiceSettings cloudChannelServiceSettings =
+ *     CloudChannelServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
+ * CloudChannelServiceClient cloudChannelServiceClient =
+ *     CloudChannelServiceClient.create(cloudChannelServiceSettings);
+ * }</pre>
+ *
+ * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link CloudChannelServiceClient}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (cloudchannel.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * <p>For example, to set the total timeout of getCustomer to 30 seconds:
+ *
+ * <pre>{@code
+ * CloudChannelServiceSettings.Builder cloudChannelServiceSettingsBuilder =
+ *     CloudChannelServiceSettings.newBuilder();
+ * cloudChannelServiceSettingsBuilder
+ *     .getCustomerSettings()
+ *     .setRetrySettings(
+ *         cloudChannelServiceSettingsBuilder
+ *             .getCustomerSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * CloudChannelServiceSettings cloudChannelServiceSettings =
+ *     cloudChannelServiceSettingsBuilder.build();
+ * }</pre>

+ * <p>======================= CloudChannelServiceClient =======================
+ *
+ * <p>Service Description: CloudChannelService enables Google cloud resellers and distributors to
+ * manage their customers, channel partners, entitlements and reports.
+ *
+ * <p>Using this service: 1. Resellers or distributors can manage a customer entity. 2. Distributors
+ * can register an authorized reseller in their channel and then enable delegated admin access for
+ * the reseller. 3. Resellers or distributors can manage entitlements for their customers.
+ *
+ * <p>The service primarily exposes the following resources: -
+ * [Customer][google.cloud.channel.v1.Customer]s: A Customer represents an entity managed by a
+ * reseller or distributor. A customer typically represents an enterprise. In an n-tier resale
+ * channel hierarchy, customers are generally represented as leaf nodes. Customers primarily have an
+ * Entitlement sub-resource discussed below.
+ *
+ * <p>- [Entitlement][google.cloud.channel.v1.Entitlement]s: An Entitlement represents an entity
+ * which provides a customer means to start using a service. Entitlements are created or updated as
+ * a result of a successful fulfillment.
+ *
+ * <p>- [ChannelPartnerLink][google.cloud.channel.v1.ChannelPartnerLink]s: A ChannelPartnerLink is
+ * an entity that identifies links between distributors and their indirect resellers in a channel.
+ *
+ * <p>Sample for CloudChannelServiceClient:

+// AUTO-GENERATED DOCUMENTATION AND CLASS.
+/**
+ * Settings class to configure an instance of {@link CloudChannelServiceStub}.
+ *
+ * <p>The default instance has everything set to sensible defaults:
+ *
+ * <ul>
+ *   <li>The default service address (cloudchannel.googleapis.com) and default port (443) are used.
+ *   <li>Credentials are acquired automatically through Application Default Credentials.
+ *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
+ * </ul>
+ *
+ * <p>The builder of this class is recursive, so contained classes are themselves builders. When
+ * build() is called, the tree of builders is called to create the complete settings object.
+ *
+ * <p>For example, to set the total timeout of getCustomer to 30 seconds:
+ *
+ * <pre>{@code
+ * CloudChannelServiceStubSettings.Builder cloudChannelServiceSettingsBuilder =
+ *     CloudChannelServiceStubSettings.newBuilder();
+ * cloudChannelServiceSettingsBuilder
+ *     .getCustomerSettings()
+ *     .setRetrySettings(
+ *         cloudChannelServiceSettingsBuilder
+ *             .getCustomerSettings()
+ *             .getRetrySettings()
+ *             .toBuilder()
+ *             .setTotalTimeout(Duration.ofSeconds(30))
+ *             .build());
+ * CloudChannelServiceStubSettings cloudChannelServiceSettings =
+ *     cloudChannelServiceSettingsBuilder.build();
+ * }</pre>

+/**

+ * CloudChannelService enables Google cloud resellers and distributors to manage
+ * their customers, channel partners, entitlements and reports.
+ * Using this service:
+ * 1. Resellers or distributors can manage a customer entity.
+ * 2. Distributors can register an authorized reseller in their channel and then
+ *    enable delegated admin access for the reseller.
+ * 3. Resellers or distributors can manage entitlements for their customers.
+ * The service primarily exposes the following resources:
+ * - [Customer][google.cloud.channel.v1.Customer]s: A Customer represents an entity managed by a reseller or
+ * distributor. A customer typically represents an enterprise. In an n-tier
+ * resale channel hierarchy, customers are generally represented as leaf nodes.
+ * Customers primarily have an Entitlement sub-resource discussed below.
+ * - [Entitlement][google.cloud.channel.v1.Entitlement]s: An Entitlement represents an entity which provides a
+ * customer means to start using a service. Entitlements are created or updated
+ * as a result of a successful fulfillment.
+ * - [ChannelPartnerLink][google.cloud.channel.v1.ChannelPartnerLink]s: A ChannelPartnerLink is an entity that identifies
+ * links between distributors and their indirect resellers in a channel.
+ * </pre>
