Member Function Documentation
◆ CanParse()
| bool Loyc.Syntax.ILiteralParser.CanParse | ( | Symbol | typeMarker | ) |
Returns true if this object has a parser for the specified type marker.
Implemented in Loyc.Syntax.LiteralHandlerTable.
◆ TryParse()
| Either<object, ILogMessage> Loyc.Syntax.ILiteralParser.TryParse | ( | UString | textValue, |
| Symbol | typeMarker | ||
| ) |
Attempts to parse a string with a given type marker.
- Parameters
-
textValue A text value that has already been preprocessed to remove escape sequences. typeMarker Indicates the type of the value. There is a standard set of type markers; please see the documention of StandardLiteralHandlers.
- Returns
- Returns either the parsed value or an error message. Does not throw.
If the problem is that the type marker doesn't have an associated parser, the returned LogMessage should not have a Severity of Error; LiteralHandlerTable uses Severity.Note for this.
Implemented in Loyc.Syntax.LiteralHandlerTable.
