Interface Callback<E>

Type Parameters:

E - type of data held in the response.

public interface Callback<E>

Callback interface for asynchronous responses. There are two ways how the receiver of a response may pass it to a copper engine. First, the receiver knows the engine and uses engine.notify. Second, the receiver puts the response into a callback object, created and passed to it by the caller. Callback objects are created using the Workflow.createCallback().
