ParserTokenManager

public ParserTokenManager(CharStream stream,
                          int lexState)

Method Detail

stateStackPop

public boolean stateStackPop()

pushes the current state onto the 'state stack', and maintains the parens counts public because we need it in PD & VM handling

Returns:

boolean : success. It can fail if the state machine gets messed up (do don't mess it up :)

stateStackPush

public boolean stateStackPush()

pops a state off the stack, and restores paren counts

Returns:

boolean : success of operation

clearStateVars

public void clearStateVars()

Clears all state variables, resets to start values, clears stateStack. Call before parsing.

setDebugStream

public void setDebugStream(PrintStream ds)

ReInit

public void ReInit(CharStream stream)

ReInit

public void ReInit(CharStream stream,
                   int lexState)

SwitchTo

public void SwitchTo(int lexState)

jjFillToken

protected Token jjFillToken()

getNextToken

public Token getNextToken()
