Class ChainedInternalContextAdapter

  • All Implemented Interfaces:
    Context, InternalContextAdapter, InternalEventContext, InternalWrapperContext
    public abstract class ChainedInternalContextAdapter
extends Object
implements InternalContextAdapter
    This is an abstract internal-use-only context implementation to be used as a subclass for other internal-use-only contexts that wrap other internal-use-only contexts. We use this context to make it easier to chain an existing context as part of a new context implementation. It just delegates everything to the inner/parent context. Subclasses then only need to override the methods relevant to them.
    Since:
    1.6
