This is an example for an API extendable with Implementations from other JARs within the classpath.
To load implementations from an interface, the ServiceLoader mechanism is used.
See example: https://github.com/tinosteinort/myhashlib-usage-example
The example shows a simple case. There is an API Module in which the myhashlib API is defined. The API allows to get the name of all supported hashing algorithms and to get an implementation by a specific name.
// get available functions
Set<String> names = HashFunctions.getAvailableHashFunctions();// get a function by name
HashFunction function = HashFunctions.getInstance("WeakHash");// execute a function
String hashValue = function.execute("Data to hash");The API project also delivers a implementation of a weak algorithm ("WeakHash"). To provide a new
implementation, just add a new dependency. See myhashlib-sha for a full implementation of the API.
Don't forget to look at this File,
if you want to provide a new implementation.
