ContinuationContext

public class ContinuationContext implements Cloneable(Code)

Contains all contextual data of one particular continuation.

It also provides some static retrieval methods to be able to access active continuations.

Active continuations are managed in a ContinuationManager so that they can be easily retrieved.
