Kson

This project is a library developed by REALTIMETECH Solution Division 2.

1. What is Kson?

1.1. Key Function

• 190% Faster then Gson

  Experience faster Object Serialize, Deserialize, and Json Parse!

• Supported extended Number, Key Types (Optional)

  Specify ambiguous numeric data, and use Array and Dict as Dict's Key!

• Automatically serialize Interface / Abstract Class field (Optional)

  Don't worry about the fields in interface, Abstract Class! (List or Map)

• Make Primary Object (Optional)

  Manage Objects included in multiple objects as one by specifying Primary Key!

1.2. Data Example

Kson is a new data format compatible with the Json standards. It solves the ambiguous number type problem of Json and supports the following data types.

{
   "longValueLower"    : 100l,
   "floatValueLower"   : 100.2f,
   "doubleValueLower"  : 100.2d,

   "longValueUpper"    : 100L,
   "floatValueUpper"   : 100.2F,
   "doubleValueUpper"  : 100.2D,

   "automaticInteger"  : 20,
   "automaticDecimal"  : 10.1

   {
     "A": "B"
   } : "Now, you can use object like a key!",

   ["A", "B"] : "And, array!"
}

2. Usage

2.1. Get Started

2.1.1. Gradle

allprojects {
   repositories {
      maven { url 'https://jitpack.io' }
   }
}

dependencies {
   implementation 'com.github.realtimetech-solution:kson:[Version]'
}

2.1.2. Maven

<repositories>
   <repository>
      <id>jitpack.io</id>
      <url>https://jitpack.io</url>
   </repository>
</repositories>

<dependency>
   <groupId>com.github.realtimetech-solution</groupId>
   <artifactId>kson</artifactId>
   <version>[Version]</version>
</dependency>

2.1.3. Jar

Please refer to the releases part of this repository.

2.2. Usage

2.2.1. Create KsonContext

All Parse, Serialize, Deserialize are available through KsonContext by default.

2.2.1.1. Create Through Builder

KsonBuilder ksonBuilder = new KsonBuilder();

KsonContext ksonContext = ksonBuilder.build();

2.2.1.2. General Creation

KsonContext ksonContext = new KsonContext();

2.2.1.3. Create Through Thread-Safe Pool

KsonBuilder ksonBuilder = new KsonBuilder();
KsonPool ksonPool = new KsonPool(ksonBuilder);

KsonContext ksonContext = ksonPool.get();

2.2.2. Serialize / Deserialize

Kson supports Serialize and Deserialize for String, Object, and JsonValue.

2.2.2.1. String to JsonValue

KsonContext ksonContext = new KsonContext();

String jsonString = "{...}";
JsonValue jsonValue = ksonContext.fromString(jsonString);

2.2.2.2. JsonValue to String

JsonValue jsonValue = ...;
String jsonString = jsonValue.toJsonString(); //Usage of standard Json format.
String ksonString = jsonValue.toKsonString(); //Usage of extended Kson format.

2.2.2.3. Object to JsonValue

KsonContext ksonContext = new KsonContext();

Person personObject = someObject;
JsonValue jsonValue = ksonContext.fromObject(personObject);

2.2.2.4. JsonValue to Object

KsonContext ksonContext = new KsonContext();

JsonValue jsonValue = ...;
Person personObject = ksonContext.toObject(Person.class, jsonValue);

2.2.2.5. String to (JsonValue) to Object

KsonContext ksonContext = new KsonContext();

String jsonString = "{...}";
Person personObject = ksonContext.toObject(Person.class, jsonString);

2.2.3. Ignore / PrimaryKey

Kson supports useful functions through Annotation.

2.2.3.1. Ignore Field

public class Person {
   private int id;
   private String name;
   
   @Ignore
   private byte[] tempArray;
}

Now, 'tempArray' field is not serialized.

2.2.3.1. Primary Key

public class Person {
   @PrimaryKey
   private int id;
   
   private String name;
}

Now, this class's instance is serialize by 'id' field instead.
