                   FilterLexer.Filter filter,
                   boolean[] stateFilter)

Method Detail

getOriginal

public Lexer getOriginal()

start

public void start(java.lang.CharSequence buffer,
                  int startOffset,
                  int endOffset,
                  int initialState)

Description copied from class: Lexer

Prepare for lexing character data from buffer passed. Internal lexer state is supposed to be initialState. It is guaranteed that the value of initialState is the same as returned by Lexer.getState() method of this lexer at condition startOffset=getTokenStart(). This method is used to incrementally re-lex changed characters using lexing data acquired from this particular lexer sometime in the past.

Overrides:

start in class DelegateLexer

Parameters:

buffer - character data for lexing.

startOffset - offset to start lexing from

endOffset - offset to stop lexing at

initialState - the initial state of the lexer.

advance

public void advance()

Description copied from class: Lexer

Advances the lexer to the next token.

Overrides:

advance in class DelegateLexer

getPrevTokenEnd

public int getPrevTokenEnd()

getCurrentPosition

public LexerPosition getCurrentPosition()

Description copied from class: Lexer

Returns the current position and state of the lexer.

Overrides:

getCurrentPosition in class LexerBase

Returns:

the lexer position and state.

restore

public void restore(LexerPosition position)

Description copied from class: Lexer

Restores the lexer to the specified state and position.

Overrides:

restore in class LexerBase

Parameters:

position - the state and position to restore to.

locateToken

public final void locateToken()
