public abstract class ContextAdaptor<ADAPTED,IN,OUT>
extends Object

Base class that holds the elements required to adapt something (i.e. a Function) to work around around a single element of a Context and output to a potentially different key of that Context.

This base class just holds the parts required for the adaption (the object being adapted, and the ContextExtractor and ContextInsertor), but doesn't actually provide any functionality.
