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">. "as_hashref" Returns a hashref representing the node in an RDF/JSON-like manner. See "as_hashref" at RDF::Trine::Model for full documentation of the hashref format. "from_sse ( $string, $context )" Parses the supplied SSE-encoded string and returns a RDF::Trine::Node object.
