Class ModuleBlockStartRecognizer

java.lang.Object

eu.cqse.check.framework.shallowparser.framework.RecognizerBase<AbapShallowParser.EAbapParserStates>

eu.cqse.check.framework.shallowparser.languages.abap.ModuleBlockStartRecognizer

public class ModuleBlockStartRecognizer
extends RecognizerBase<AbapShallowParser.EAbapParserStates>

Precondition recognizer that matches if a module block (not a module statement) starts at the current location, but does not consume any tokens. A module block starts with one of:

 module x.
 module x input.
 module x output.
 

and ends with endmodule.

This recognizer is used to distinguish module statements (that invoke a module) from module declarations (matched by this recognizer).

Note that module statements cannot appear inside module blocks.

Method Detail

matchesLocally

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

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

Overrides:

matchesLocally in class RecognizerBase<AbapShallowParser.EAbapParserStates>

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.
