Constructor & Destructor Documentation

Triple() [1/2]

Dataquay::Triple::Triple ( )

inline

Construct a triple of three Nothing nodes.

Definition at line 53 of file Triple.h.

Triple() [2/2]

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.
