Extension Methods| Name | Description | |
|---|---|---|

| Apply(IEnumerable<Triple>) | Overloaded.
Applies the triples to an RDF Handler.

RemarksIn most parsing scenarios this handler is not suitable for usage as it may unintentionally modify the RDF data being parsed, in non-parsing scenarios where this handler is instead being used as a means to generate RDF data from some non-RDF source it may prove very useful.
This handler essentially works by redirecting all calls to the argument taking form of CreateBlankNode() with the non-argument form which should always generate a new blank node thus guaranteeing the uniqueness of nodes.
