ANTLR3_TREE_WALK_STATE_struct (3) - Linux Manuals
NAME
ANTLR3_TREE_WALK_STATE_struct -
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.
SYNOPSIS
#include <antlr3commontreenodestream.h>
Data Fields
ANTLR3_MARKER absoluteNodeIndex
ANTLR3_UINT32 currentChildIndex
pANTLR3_BASE_TREE currentNode
ANTLR3_UINT32 head
pANTLR3_BASE_TREE * lookAhead
ANTLR3_UINT32 lookAheadLength
ANTLR3_UINT32 nodeStackSize
pANTLR3_BASE_TREE previousNode
ANTLR3_UINT32 tail
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.
