Constructor & Destructor Documentation

Dataquay::Triple::Triple

(

)

[inline]

Construct a triple of three Nothing nodes.

Definition at line 53 of file Triple.h.

Dataquay::Triple::Triple	(	Node	_a,
		Node	_b,
		Node	_c
	)			[inline]

Construct a triple of the three given nodes.

Our triples may contain anything, including the Nothing node type for undefined elements (used in wildcard matching, etc).

However, in order to be inserted in the RDF store, a triple must have either URI or Blank type for its first (or subject) node, URI for its second (or predicate) node, and either URI, Blank, or Literal type for its third (or object) node. See the following constructor for some simple assistance in constructing typical statement triples.

Definition at line 68 of file Triple.h.

Dataquay::Triple::Triple	(	QString	a_uri,
		QString	b_uri,
		Node	_c
	)			[inline]

Construct a triple of two URIs and an arbitrary node.

This constructor simplifies constructing complete RDF statements with subject and predicate both URIs.

Definition at line 77 of file Triple.h.

Dataquay::Triple::Triple	(	Node	_a,
		QString	b_uri,
		Node	_c
	)			[inline]

Construct a triple of Node, URI, and an arbitrary node.
