Interface FailedContext

All Superinterfaces:

ContextBase, Failure, Identifiable

All Known Implementing Classes:

FailedContextImpl

public interface FailedContext
extends Failure, ContextBase

Represents Context that failed. A typical case would be that its ContextStartHandler threw an exception.

The underlying Evaluator is still accessible and a new context can be established. Note that REEF can't guarantee consistency of the Evaluator for all applications. It is up to the application to decide whether it is safe to keep using the Evaluator.
