public class TCustomParser
extends Object

Base parser of all databases.

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	TCustomParser.ProofLrConfiguration The automaton's configuration at the proof cutoff: the state stack as it stood when the parser first needed a token at or beyond the cutoff, plus every reduction performed before that point.
static class	TCustomParser.ProofReduction One reduction the automaton performed, recorded before the stack is popped.

Field Detail

PROOF_LR_STOPPED_AT_CUTOFF

public static final int PROOF_LR_STOPPED_AT_CUTOFF

Returned by do_yyparse(int[], int[], int[], int[], int[], int[], int[], int[], int[], int[], int[], java.util.Map<java.lang.Integer, int[]>) when it stopped at the proof cutoff.

Method Detail

getProofRecoveryEvents

public int getProofRecoveryEvents()

proofRecoveryEvents

getProofKeywordRollbackEvents

public int getProofKeywordRollbackEvents()

See Also:

proofKeywordRollbackEvents

setProofLrCutoffOffset

public void setProofLrCutoffOffset(long offset)

Arm the observer. Must be called before yyparse(). Observation is read-only: the parse proceeds exactly as it otherwise would, up to the cutoff, at which point it stops WITHOUT entering error recovery (recovery unwinds the very stack we are trying to read).

getProofLrConfiguration

public TCustomParser.ProofLrConfiguration getProofLrConfiguration()

The configuration captured at the cutoff, or null if it was never reached.

getNf

public TNodeFactory getNf()

do_yyparse

public int do_yyparse(int[] p_yyd,
                      int[] p_yyal,
                      int[] p_yyah,
