Class ChainedInternalContextAdapter

java.lang.Object
org.apache.velocity.context.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.
