IClientContext

public class MultiClientContext
extends java.lang.Object
implements IClientContext

Implements a multi-context, which is a compound context representing a group of client contexts.

It's matcher matches an EObject if all of child contexts match that EObject.

It includes an IElementType or an IEditHelperAdviceDescriptor if all of the child contexts include that IElementType or IEditHelperAdviceDescriptor.

          The ID of all multi-contexts.
 
Constructor Summary
MultiClientContext (java.util.Collection childContexts)
          Initializes me with my child contexts.
 
Method Summary
 void add ( IClientContext context)

 void bindId (java.lang.String typeId)
          Binds the typeId to each of my children.
 void bindPattern (java.util.regex.Pattern pattern)
          Binds the pattern to each of my children.
 boolean equals (java.lang.Object obj)
          The children fully determine equality.
 java.util.Collection getChildren ()
          Returns a list of IClientContexts contained in this multi-context, or an empty list if this is not a multi-context.
 java.lang.String getId ()
