InMemoryQuadDataset Class

An in-memory dataset that operates in terms of quads, underlying storage is identical to a InMemoryDataset though this dataset should be more performant for queries that access named graphs frequently.

Constructors

	Name	Description
	InMemoryQuadDataset	Creates a new in-memory dataset using the default in-memory TripleStore as the underlying storage.
	InMemoryQuadDataset(Boolean)	Creates a new in-memory dataset using the default in-memory TripleStore as the underlying storage.
	InMemoryQuadDataset(IGraph)	Creates a new in-memory dataset containing initially just the given graph and treating the given graph as the default graph of the dataset.
	InMemoryQuadDataset(IInMemoryQueryableStore)	Creates a new In-Memory dataset.
	InMemoryQuadDataset(IInMemoryQueryableStore, Boolean)	Creates a new In-Memory dataset.
	InMemoryQuadDataset(IInMemoryQueryableStore, Uri)	Creates a new In-Memory dataset.
