 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] |
| Gets or sets the object to which error messages are sent. The default object is LogExceptionErrorSink, which throws an exception if an error occurs. More... | |
| 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... | |
| Protected Member Functions inherited from Loyc.Syntax.BaseParser< Token, MatchType > | |
| BaseParser (ISourceFile?file=null, int startIndex=0) | |
| Initializes the base class. More... | |
| abstract MatchType | EofInt () |
| Returns the value used for EOF (normally 0) More... | |
| abstract Token | LT (int i) |
Returns the token at lookahead i (e.g. Source[InputPosition + i] if the tokens come from a list called Source) More... | |
| abstract string | ToString (MatchType tokenType) |
| Returns a string representation of the specified token type. These strings are used in error messages. More... | |
| virtual int | LaIndexToCharIndex (int lookaheadIndex) |
| Converts a lookahead token index to a character index (used for error reporting). More... | |
| virtual object | LaIndexToMsgContext (int lookaheadIndex) |
| Converts a lookahead token index to a SourceRange (or to a string if SourceFile was initialized to null.) More... | |
| virtual void | Error (int lookaheadIndex, string message) |
| Records an error or throws an exception. More... | |
| virtual void | Error (int lookaheadIndex, string format, params object?[] args) |
