Method Detail

matchesLocally

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

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

Overrides:

matchesLocally in class RecognizerBase<ECobolParserState>

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.
