Fields

Modifier and Type	Field	Description
static Dataset	ALL_LOCAL	The query dataset where the default graph is the union of all local (non-virtual) graphs.
static Dataset	DEFAULT	The default query dataset
static Dataset	EMPTY	A Dataset which is empty, that is, it's comprised of zero graphs.
static Dataset	NO_DATASET	Constant for specifying that there is no specific dataset; a Query should use whatever information is in its from/from named clauses.
