       RDF::Trine::Node::Literal - RDF Node class for literals

       This document describes RDF::Trine::Node::Literal version 1.019

       Beyond the methods documented below, this class inherits	methods	from
       the RDF::Trine::Node class.

       "new ( $string, $lang, $datatype, $canonical_flag )"
	   Returns a new Literal structure.

	   Returns the string value of the literal.

	   Returns the language	tag of the ltieral.

	   Returns the datatype	of the literal.

	   Returns the literal value.

	   Returns the SSE string for this literal.

	   Returns a string representation of the node.

	   Returns the node in a string	form suitable for NTriples

	   Returns the type string of this node.

	   Returns true	if this	literal	is language-tagged, false otherwise.

	   Returns true	if this	literal	is datatyped, false otherwise.

       "equal (	$node )"
	   Returns true	if the two nodes are equal, false otherwise.

	   Returns a new literal node object whose value is in canonical form
	   (where applicable).

       "canonicalize_literal_value ( $string, $datatype, $warn )"
	   If $datatype	is a recognized	datatype, returns the canonical
	   lexical representation of the value $string.	Otherwise returns

	   Currently, xsd:integer, xsd:decimal,	and xsd:boolean	are
	   canonicalized.  Additionally, invalid lexical forms for xsd:float,
	   xsd:double, and xsd:dateTime	will trigger a warning.

	   Returns true	if the node is of a recognized datatype	and has	a
	   valid lexical form for that datatype. If the	lexical	form is
	   invalid, returns false. If the datatype is unrecognized, returns

	   Returns true	if the literal is a known (xsd)	numeric	type.

	   Returns the numeric value of	the literal (even if the literal isn't
	   a known numeric type.
