Methods

Modifier and Type	Method and Description
static Graph	createDataBagGraph(ThresholdPolicy<Triple> thresholdPolicy) A graph backed by a DistinctDataBag<Triple>.
static Graph	createDefaultGraph() Create a graph - ARQ-wide default type
static Graph	createGraphMem() Create a graph that is a Jena memory graph
static Graph	createJenaDefaultGraph() Create a graph - always the Jena default graph type
static Graph	createPlainGraph() Very simple graph that uses same-term for find() (small-scale use only)
static Model	makeDataBagModel(ThresholdPolicy<Triple> thresholdPolicy) Create a model over a DataBag graph (will spill to disk when it get large)
static Model	makeDefaultModel() Create a model over a default graph (ARQ-wide for degault graph type)
static Model	makeJenaDefaultModel() Guaranteed call-through to Jena's ModelFactory operation
static Model	makePlainModel() Create a model over a plain graph (small-scale use only)
