Class DefaultJAXXContext

java.lang.Object

org.nuiton.jaxx.runtime.api.context.DefaultJAXXContext

All Implemented Interfaces:

JAXXContext

Direct Known Subclasses:

DefaultApplicationContext, JAXXInitialContext

public class DefaultJAXXContext
extends Object
implements JAXXContext

The default JAXXContext to be used in a JAXXObject by delegation.

The values are store in a Map but we can not use directly the values as key.

Because, it does not work if we add for the same object multi entries (named and unamed)...

We prefer use as entry the JAXXContextEntryDef associated with the value.
