       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

       "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 serialization.

           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 $string.

           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

           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 zero-but-true.

           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
