Class XtendSkipToEndOfStatementRecognizer

java.lang.Object

eu.cqse.check.framework.shallowparser.framework.RecognizerBase<XtendShallowParser.EXtendShallowParserState>

eu.cqse.check.framework.shallowparser.languages.xtend.XtendSkipToEndOfStatementRecognizer

public class XtendSkipToEndOfStatementRecognizer
extends RecognizerBase<XtendShallowParser.EXtendShallowParserState>

We have to use this recognizer to match single statements in xtend, because there is no indicator like semicolon or end of line, that marks the end of a statement. Additionally xtend allows multiple statements in one single line.
The recognizer recognizes specific constructs within a simple statement, namely: try, switch and if statements.

Method Detail

matchesLocally

protected int matchesLocally(ParserState<XtendShallowParser.EXtendShallowParserState> parserState,
                             java.util.List<IToken> tokens,
                             int offset)

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

Overrides:

matchesLocally in class RecognizerBase<XtendShallowParser.EXtendShallowParserState>

Parameters:

parserState - the current state of the underlying parser.

tokens - the list of tokens.

offset - 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.
