Constructor Detail

SimpleStatement

protected SimpleStatement(Resource subject,
                          IRI predicate,
                          Value object)

Creates a new Statement with the supplied subject, predicate and object. *

Note that creating SimpleStatement objects directly via this constructor is not the recommended approach. Instead, use a ValueFactory (obtained from your repository or by using SimpleValueFactory.getInstance()) to create new Statement objects.

Parameters:

subject - The statement's subject, must not be null.

predicate - The statement's predicate, must not be null.

object - The statement's object, must not be null.
