protected TreeParserSharedInputState	inputState Nesting level of registered handlers
protected AST	returnAST AST return value for a rule is squirreled away here
protected String[]	tokenNames Table of token type to token names

Field Detail

ASTNULL

public static ASTNULLType ASTNULL

Enabled: The AST Null object; the parsing cursor is set to this when it is found to be null. This way, we can test the token type of a node without having to have tests for null everywhere.

_retTree

protected AST _retTree

Where did this rule leave off parsing; avoids a return parameter

inputState

protected TreeParserSharedInputState inputState

Nesting level of registered handlers

tokenNames

protected String[] tokenNames

Table of token type to token names

returnAST

protected AST returnAST

AST return value for a rule is squirreled away here

astFactory

protected ASTFactory astFactory

AST support code; parser and treeparser delegate to this object

traceDepth

protected int traceDepth

Used to keep track of indentdepth for traceIn/Out

Method Detail

getAST

public AST getAST()

Enabled: Get the AST return value squirreled away in the parser

getASTFactory

public ASTFactory getASTFactory()

Enabled:

getTokenName

public String getTokenName(int num)

Enabled:

getTokenNames

public String[] getTokenNames()

Enabled:

match

protected void match(AST t,
                     int ttype)
              throws MismatchedTokenException

MismatchedTokenException

match

public void match(AST t,
                  BitSet b)
           throws MismatchedTokenException

Enabled: Make sure current lookahead symbol matches the given set Throw an exception upon mismatch, which is catch by either the error handler or by the syntactic predicate.

MismatchedTokenException

matchNot

protected void matchNot(AST t,
                        int ttype)
                 throws MismatchedTokenException

MismatchedTokenException

panic

public static void panic()

Enabled:

reportError

public void reportError(RecognitionException ex)

Enabled: Parser error-reporting function can be overridden in subclass

reportError

public void reportError(String s)

Enabled: Parser error-reporting function can be overridden in subclass

reportWarning

public void reportWarning(String s)

Enabled: Parser warning-reporting function can be overridden in subclass

setASTFactory

public void setASTFactory(ASTFactory f)

Enabled: Specify an object with support code (shared by Parser and TreeParser. Normally, the programmer does not play with this, using setASTNodeType instead.

setASTNodeType

public void setASTNodeType(String nodeType)

Enabled: Specify the type of node to create during tree building

setASTNodeClass

public void setASTNodeClass(String nodeType)

Enabled: Specify the type of node to create during tree building

traceIndent

public void traceIndent()

Enabled:

traceIn

public void traceIn(String rname,
                    AST t)

Enabled:

traceOut

public void traceOut(String rname,
                     AST t)

Enabled:
