java.lang.Object

eu.cqse.check.framework.shallowparser.framework.RecognizerBase<ECobolParserState>

eu.cqse.check.framework.shallowparser.languages.cobol.ConditionalClauseWithEndScopeRecognizer

public class ConditionalClauseWithEndScopeRecognizer
extends RecognizerBase<ECobolParserState>

For Cobol scope statements with conditional clauses (e.g. WRITE), this recognizer helps to tell if the next token type is an explicit scope terminator or not.

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.
