NAMEsrc/antlr3treeparser.c − Implementation of the tree parser and overrides for the base recognizer​.

SYNOPSIS
#include <antlr3treeparser​.h>

FunctionsANTLR3_API void antlr3MTNExceptionNew (pANTLR3_BASE_RECOGNIZER recognizer)
Creates a new Mismatched Tree Nde Exception and inserts in the recognizer exception stack​.
ANTLR3_API pANTLR3_TREE_PARSER antlr3TreeParserNewStream (ANTLR3_UINT32 sizeHint, pANTLR3_COMMON_TREE_NODE_STREAM ctnstream, pANTLR3_RECOGNIZER_SHARED_STATE state)
static void freeParser (pANTLR3_TREE_PARSER parser)
static void * getCurrentInputSymbol (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_INT_STREAM istream)
static void * getMissingSymbol (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_INT_STREAM istream, pANTLR3_EXCEPTION e, ANTLR3_UINT32 expectedTokenType, pANTLR3_BITSET_LIST follow)
static pANTLR3_COMMON_TREE_NODE_STREAM getTreeNodeStream (pANTLR3_TREE_PARSER parser)
Return a pointer to the input stream​.
static void mismatch (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_UINT32 ttype, pANTLR3_BITSET_LIST follow)
Override for standard base recognizer mismatch function as we have DOWN/UP nodes in the stream that have no line info, plus we want to alter the exception type​.
static void setTreeNodeStream (pANTLR3_TREE_PARSER parser, pANTLR3_COMMON_TREE_NODE_STREAM input)
Set the input stream and reset the parser​.

Detailed DescriptionImplementation of the tree parser and overrides for the base recognizer​.
