Interface Continuation<R>

Type Parameters:

R - the result type

All Known Implementing Classes:

AbstractPersistenceEnvironment.DefaultFailureContinuation, NullImplementation.NullContinuation, NullImplementation.NullPersistentStore.Token

public interface Continuation<R>

Continuation interface is used to implement asynchronous post-processing, the pattern that is also known as the "Continuation-passing style".

Most commonly, a continuation can be used to encode a single program control mechanism (i.e. a logical "return"). Advanced usages may also need to encode multiple control mechanisms (e.g. an exceptional execution path). For such usages, each control path could be explicitly represented as a separate Continuation, e.g.:

 void doAsync(Continuation<Result> contNormal, Continuation<Exception> contExceptional);
