Syntax

public class UnionTripleCollection : BaseTripleCollection, IEnumerable<Triple>, IEnumerable, IDisposable

Remarks

The union consists of a Base collection which is the collection that Triples can actually be added to and deleted from and any number of additional collections which are read-only as far as the union is concerned (this does not mean they cannot be altered elsewhere by other code).

Constructors

UnionTripleCollection(BaseTripleCollection, IEnumerable<BaseTripleCollection>)

Creates a new Union Triple Collection which is a union of any number of collections.

Declaration

public UnionTripleCollection(BaseTripleCollection baseTriples, IEnumerable<BaseTripleCollection> additionalTriples)

Parameters

Type	Name	Description
BaseTripleCollection	baseTriples	Base Triple Collection.
System.Collections.Generic.IEnumerable<T><BaseTripleCollection>	additionalTriples	Additional Triple Collection(s).

Remarks

The union consists of a Base collection which is the collection that Triples can actually be added to and deleted from and any number of additional collections which are read-only as far as the union is concerned (this does not mean they cannot be altered elsewhere by other code).

UnionTripleCollection(BaseTripleCollection, BaseTripleCollection)

Creates a new Union Triple Collection which is a union of two collections.

Declaration

public UnionTripleCollection(BaseTripleCollection baseTriples, BaseTripleCollection additionalTriples)

Parameters

Type	Name	Description
BaseTripleCollection	baseTriples	Base Triple Collection.
BaseTripleCollection	additionalTriples	Additional Triple Collection.

Remarks

The union consists of a Base collection which is the collection that Triples can actually be added to and deleted from and any number of additional collections which are read-only as far as the union is concerned (this does not mean they cannot be altered elsewhere by other code).

Properties

Asserted

Gets the triples that are asserted in the collection.

Declaration

public override IEnumerable<Triple> Asserted { get; }

Property Value

Type	Description
System.Collections.Generic.IEnumerable<T><Triple>

Overrides

BaseTripleCollection.Asserted

Remarks

This returns the same set of triples as the enumerator on this class, but as an System.Collections.Generic.IEnumerable<T> instance.

Count

Gets the count of Triples in this union.

Declaration

public override int Count { get; }

Property Value

Type	Description
int

Overrides

BaseTripleCollection.Count

Remarks

The Count is the total number of Triples, this may be different from the number of distinct triples.

this[Triple]

Declaration

public override bool ContainsQuoted(Triple t)

Parameters

Type	Name	Description
Triple	t	Triple to test.

Returns

Type	Description
