⊟ Contains Method

Returns whether the endpoint mentions a resource.

public bool Contains (SemWeb.Resource resource)

⊟ Parameters

resource

An entity or literal.

⊟ Returns

Whether the endpoint has any statements mentioning the given resource.

⊟ Remarks

Due to the nature of RDF and the limitations of SPARQL, passing a BNode to this method will immediately return false. There is no way to include a BNode from the remote store inside a query.

This method currently throws NotImplementedException. Sorry! (If you want the method, feel free to submit a patch!)
