Syntax

public class UniqueBlankNodesHandler : BaseRdfHandler, IWrappingRdfHandler, IRdfHandler, INodeFactory

Remarks

In 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.

Constructors

UniqueBlankNodesHandler(IRdfHandler)

Creates a new Unique Blank Nodes handler.

Declaration

public UniqueBlankNodesHandler(IRdfHandler handler)

Parameters
