An base class designed for parsers that use LLLPG (Loyc LL(k) Parser Generator). Note: this is the old (harder to use) base class. You should use BaseParserForList{Token, LaType} instead. This class is now an alias for BaseParser{Token,int}. More...

| void | MatchError (bool inverted, params MatchType[] expected) |
| virtual void | MatchError (bool inverted, IEnumerable< MatchType > expected) |
| Handles an error that occurs during Match() or MatchExcept() More... | |

Additional Inherited Members | |
| Public static fields inherited from Loyc.Syntax.BaseParser< Token, MatchType > | |
| static readonly IMessageSink | LogExceptionErrorSink |
| Throws LogException when it receives an error. Non-errors are sent to MessageSink.Default. More... | |
| static readonly IMessageSink | FormatExceptionErrorSink |
| Properties inherited from Loyc.Syntax.BaseParser< Token, MatchType > | |
| IMessageSink | ErrorSink [get, set] |

| ISourceFile | SourceFile [get] |
| The ISourceFile object that was provided to the constructor, if any. More... | |
| Token | LT0 [get] |
| Next token to parse (cached; is set to LT(0) whenever InputPosition is changed). More... | |
| int | InputPosition [get, set] |
| Current position of the next token to be parsed. More... | |
| abstract MatchType | LA0Int [get] |
| Returns the token type of _lt0 (normally _lt0.TypeInt) More... | |
