Detailed Description

Context sensitive node.

Defines a class of nodes, that can perform context sensitive matching. After a match function is called does some chack on what was matched. These nodes try to be invisible to all functions.

virtual int ContextMatch::getLength (   )  const [inline, virtual]

Returns teh length of the list -- valid only for List and ContextMatch. Reimplemented from Node. Definition at line 76 of file ctree.h. References Node::getLength(), and node.

virtual string ContextMatch::getName (   )  const [inline, virtual]

Returs string representing node type or name for List. Implements Node. Definition at line 32 of file ctree.h. References Node::getName(), and node.

virtual SType ContextMatch::getType (   )  const [inline, virtual]
