Detailed Description

This structure is used to save the state information in the treenodestream when walking ahead with cyclic DFA or for syntactic predicates, we need to record the state of the tree node stream.

This class wraps up the current state of the CommonTreeNodeStream. Calling mark() will push another of these on the markers stack.

Data Fields
ANTLR3_MARKER	absoluteNodeIndex

pANTLR3_BASE_TREE *	lookAhead
ANTLR3_UINT32	lookAheadLength
ANTLR3_UINT32	nodeStackSize
