bool Loyc.Syntax.ILiteralParser.CanParse

(

Symbol

typeMarker

)

Returns true if this object has a parser for the specified type marker. Returns false if typeMarker == null.

Implemented in Loyc.Syntax.LiteralHandlerTable.

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. If typeMarker is null, it is treated as an empty string.

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.
