Method Detail

matchesLocally

public int matchesLocally(ParserState<STATE> parserState,
                          java.util.List<IToken> tokens,
                          int startOffset)

Attempts to match the recognizer locally (without respecting tail recognizers).

Overrides:

matchesLocally in class RecognizerBase<STATE extends java.lang.Enum<STATE>>

Parameters:

parserState - the current state of the underlying parser.

tokens - the list of tokens.

startOffset - the current offset into the tokens from where to start matching.

Returns:

the new offset (position right behind the match) or RecognizerBase.NO_MATCH if matching was not possible at this position.

getRecognizerStringRepresentation

protected java.lang.String getRecognizerStringRepresentation()

Returns the default string representation of this recognizer: its short class name. Used in RecognizerBase.toString() to ease debugging. May be overwritten by subclasses to provide better debugging information. This default implementation is sufficient for all recognizers that don't take any arguments. Other recognizers should overwrite this to make their arguments visible to the debugging user if they are helpful.

Overrides:

getRecognizerStringRepresentation in class RecognizerBase<STATE extends java.lang.Enum<STATE>>
