Property Value

Type	Description
int

Overrides

WrapperGraphCollection.Count

GraphNames

Provides an enumeration of the names of all of teh graphs in the collection.

Declaration

public override IEnumerable<IRefNode> GraphNames { get; }

Property Value

Type	Description
IEnumerable<IRefNode>

Overrides

WrapperGraphCollection.GraphNames

GraphUris

Provides access to the Graph URIs of Graphs in the Collection.

Declaration

[Obsolete]
public override IEnumerable<Uri> GraphUris { get; }

Property Value

Type	Description
IEnumerable<Uri>

Overrides

WrapperGraphCollection.GraphUris

this[Uri]

Gets a Graph from the Collection.

Declaration

[Obsolete]
public override IGraph this[Uri graphUri] { get; }

Parameters

Type	Name	Description
Uri	graphUri	Graph Uri.

Property Value

Type	Description
IGraph

Overrides

Parameters

Type	Name	Description
IRefNode	graphName	The name of the graph to retrieve.

Property Value

Type	Description
IGraph

Overrides

WrapperGraphCollection.this[IRefNode]

Remarks

The null value is used to reference the default graph.

Methods

Add(IGraph, bool)

Adds a Graph to the Collection.

Declaration

public override bool Add(IGraph g, bool mergeIfExists)

Parameters

Type	Name	Description
IGraph	g	Graph to add.
bool	mergeIfExists	Sets whether the Graph should be merged with an existing Graph of the same Uri if present.

Returns

Type	Description
bool

Overrides

WrapperGraphCollection.Add(IGraph, bool)

Exceptions

Type	Condition
RdfException	Throws an RDF Exception if the Graph has no Base Uri or if the Graph already exists in the Collection and the mergeIfExists parameter was not set to true.

Contains(Uri)

Checks whether the Graph with the given Uri exists in this Graph Collection.

Declaration

[Obsolete]
public override bool Contains(Uri graphUri)

Parameters

Type	Name	Description
Uri	graphUri	Graph Uri to test.
