Interface Handler<Value,Argument>

Type Parameters:

Value - type of value to return.

Argument - type of argument.

public interface Handler<Value,Argument>

Generic logic that process an argument and return a value. This Handler and Callback are in fact the same beast but with separated usage pattern: handler is called to process an argument and returns a value - handy for specialization of generic logic whereas callback is used at completion of an asynchronous task and does not return value since value is passed as argument.
