GenericStatement
Creates a new Statement with the supplied subject, predicate and object for the specified associated context.Note that creating an objects directly via this constructor is not the recommended approach. Instead, use a

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.context
- The statement's context, null to indicate no context is associated.
