NAME

       RDF::Trine::Node - Base class for RDF Nodes

VERSION

       This document describes RDF::Trine::Node version 1.007

FUNCTIONS

       "ntriples_escape ( $value )"
           Returns the passed string value with special characters (control characters, Unicode,
           etc.) escaped, suitable for printing inside an N-Triples or Turtle encoded literal.

METHODS

       "is_node"
           Returns true if this object is a RDF node, false otherwise.

       "is_nil"
           Returns true if this object is the nil-valued node.

       "is_blank"
           Returns true if this RDF node is a blank node, false otherwise.

       "is_resource"
           Returns true if this RDF node is a resource, false otherwise.

       "is_literal"
           Returns true if this RDF node is a literal, false otherwise.

       "is_variable"
           Returns true if this RDF node is a variable, false otherwise.

       "as_string"
           Returns the node in a string form.

       "as_ntriples"
           Returns the node in a string form suitable for NTriples serialization.

       "sse"
           Returns the SSE serialization of the node.

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

       "compare ( $node_a, $node_b )"
           Returns -1, 0, or 1 if $node_a sorts less than, equal to, or greater than $node_b in
           the defined SPARQL ordering, respectively. This function may be used as the function
           argument to "<sort">.

       "from_sse ( $string, $context )"
           Parses the supplied SSE-encoded string and returns a RDF::Trine::Node object.
