19           Returns true if this object is a RDF node, false otherwise.
20
21       "is_nil"
22           Returns true if this object is the nil-valued node.
23
24       "is_blank"
25           Returns true if this RDF node is a blank node, false otherwise.
26
27       "is_resource"
28           Returns true if this RDF node is a resource, false otherwise.
29
30       "is_literal"

32
33       "is_variable"
34           Returns true if this RDF node is a variable, false otherwise.
35
36       "as_string"

38
39       "as_ntriples"

47           Returns true if the two nodes are equal, false otherwise.
48
49       "compare ( $node_a, $node_b )"
50           Returns -1, 0, or 1 if $node_a sorts less than, equal to, or
51           greater than $node_b in the defined SPARQL ordering, respectively.
52           This function may be used as the function argument to "<sort">.
53
54       "as_hashref"
55           Returns a hashref representing the node in an RDF/JSON-like manner.
56
