Interface InterceptingCallback<T>

Type Parameters:

T - the generic type of the operation's return type

public interface InterceptingCallback<T>

An operation is intercepting when its return type matches this class.

The getResult() method gives access to the intercepting operation actual return type, while the other methods are use for getting notifications about the execution of the intercepted chain.

A new instance of this class should be returned per each invokation to the intercepting operation.

Since:

1.0
