This document describes RDF::Trine::Node version 1.019
.SH FUNCTIONS
.IX Header "FUNCTIONS"
.ie n .IP """ntriples_escape ( $value )""" 4
.el .IP "\f(CWntriples_escape ( $value )\fR" 4
.IX Item "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.
.SH METHODS
.IX Header "METHODS"
.ie n .IP """is_node""" 4
.el .IP \f(CWis_node\fR 4
.IX Item "is_node"
Returns true if this object is a RDF node, false otherwise.
.ie n .IP """is_nil""" 4
.el .IP \f(CWis_nil\fR 4
.IX Item "is_nil"
Returns true if this object is the nil-valued node.
.ie n .IP """is_blank""" 4
.el .IP \f(CWis_blank\fR 4
.IX Item "is_blank"
Returns true if this RDF node is a blank node, false otherwise.
.ie n .IP """is_resource""" 4
.el .IP \f(CWis_resource\fR 4
.IX Item "is_resource"
Returns true if this RDF node is a resource, false otherwise.
.ie n .IP """is_literal""" 4
.el .IP \f(CWis_literal\fR 4
.IX Item "is_literal"
Returns true if this RDF node is a literal, false otherwise.
.ie n .IP """is_variable""" 4
.el .IP \f(CWis_variable\fR 4
.IX Item "is_variable"
Returns true if this RDF node is a variable, false otherwise.
.ie n .IP """as_string""" 4
.el .IP \f(CWas_string\fR 4
.IX Item "as_string"
Returns the node in a string form.
.ie n .IP """as_ntriples""" 4
.el .IP \f(CWas_ntriples\fR 4
.IX Item "as_ntriples"
Returns the node in a string form suitable for NTriples serialization.
.ie n .IP """sse""" 4
.el .IP \f(CWsse\fR 4
.IX Item "sse"
Returns the SSE serialization of the node.
.ie n .IP """equal ( $node )""" 4
.el .IP "\f(CWequal ( $node )\fR" 4
.IX Item "equal ( $node )"
Returns true if the two nodes are equal, false otherwise.
.ie n .IP """compare ( $node_a, $node_b )""" 4
.el .IP "\f(CWcompare ( $node_a, $node_b )\fR" 4
.IX Item "compare ( $node_a, $node_b )"
Returns \-1, 0, or 1 if \f(CW$node_a\fR sorts less than, equal to, or greater than
\&\f(CW$node_b\fR in the defined SPARQL ordering, respectively. This function may be
used as the function argument to \f(CW\*(C`<sort\*(C'\fR>.
.ie n .IP """as_hashref""" 4
.el .IP \f(CWas_hashref\fR 4
.IX Item "as_hashref"
Returns a hashref representing the node in an RDF/JSON\-like manner.
.Sp
See \f(CW\*(C`as_hashref\*(C'\fR at RDF::Trine::Model for full documentation of the
hashref format.
.ie n .IP """from_sse ( $string, $context )""" 4
.el .IP "\f(CWfrom_sse ( $string, $context )\fR" 4
.IX Item "from_sse ( $string, $context )"
Parses the supplied SSE-encoded string and returns a RDF::Trine::Node object.
