SYNOPSIS
#include <antlr3baserecognizer​.h>
Functionsstatic ANTLR3_BOOLEAN alreadyParsedRule (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_MARKER ruleIndex)
Has this rule already parsed input at the current index in the input stream? Return ANTLR3_TRUE if we have and ANTLR3_FALSE if we have not​. ANTLR3_API pANTLR3_BASE_RECOGNIZER antlr3BaseRecognizerNew (ANTLR3_UINT32 type, ANTLR3_UINT32 sizeHint, pANTLR3_RECOGNIZER_SHARED_STATE state)

Creates a new Mismatched Token Exception and inserts in the recognizer exception stack​. ANTLR3_API void antlr3RecognitionExceptionNew (pANTLR3_BASE_RECOGNIZER recognizer)

static void * getMissingSymbol (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_INT_STREAM istream, pANTLR3_EXCEPTION e, ANTLR3_UINT32 expectedTokenType, pANTLR3_BITSET_LIST follow)
static ANTLR3_UINT32 getNumberOfSyntaxErrors (pANTLR3_BASE_RECOGNIZER recognizer)
Return how many syntax errors were detected by this recognizer​. static pANTLR3_STACK getRuleInvocationStack (pANTLR3_BASE_RECOGNIZER recognizer)
Return the rule invocation stack (how we got here in the parse​. static pANTLR3_STACK getRuleInvocationStackNamed (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_UINT8 name)
static ANTLR3_MARKER getRuleMemoization (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_INTKEY ruleIndex, ANTLR3_MARKER ruleParseStart)
Pointer to a function to return whether the rule has parsed input starting at the supplied start index before​. static void * match (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_UINT32 ttype, pANTLR3_BITSET_LIST follow)
Match current input symbol against ttype​. static void matchAny (pANTLR3_BASE_RECOGNIZER recognizer)
Consumes the next token, whatever it is, and resets the recognizer state so that it is not in error​. static void memoize (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_MARKER ruleIndex, ANTLR3_MARKER ruleParseStart)
Record whether or not this rule parsed the input at this position successfully​. static void mismatch (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_UINT32 ttype, pANTLR3_BITSET_LIST follow)
Factor out what to do upon token mismatch so tree parsers can behave differently​. static ANTLR3_BOOLEAN mismatchIsMissingToken (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_INT_STREAM is, pANTLR3_BITSET_LIST follow)
static ANTLR3_BOOLEAN mismatchIsUnwantedToken (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_INT_STREAM is, ANTLR3_UINT32 ttype)
static void recover (pANTLR3_BASE_RECOGNIZER recognizer)
Recover from an error found on the input stream​. static ANTLR3_BOOLEAN recoverFromMismatchedElement (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_BITSET_LIST followBits)
This code is factored out from mismatched token and mismatched set recovery​. static void * recoverFromMismatchedSet (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_BITSET_LIST follow)
static void * recoverFromMismatchedToken (pANTLR3_BASE_RECOGNIZER recognizer, ANTLR3_UINT32 ttype, pANTLR3_BITSET_LIST follow)
Attempt to recover from a single missing or extra token​. static void reportError (pANTLR3_BASE_RECOGNIZER recognizer)
Report a recognition problem​. static void reset (pANTLR3_BASE_RECOGNIZER recognizer)
static ANTLR3_BOOLEAN synpred (pANTLR3_BASE_RECOGNIZER recognizer, void *ctx, void(*predicate)(void *ctx))
A syntactic predicate​. static pANTLR3_HASH_TABLE toStrings (pANTLR3_BASE_RECOGNIZER recognizer, pANTLR3_HASH_TABLE tokens)
Convenience method for template rewrites - NYI​.
Detailed DescriptionContains the base functions that all recognizers require​. Any function can be overridden by a lexer/parser/tree parser or by the ANTLR3 programmer​.
