Class UniqueBlankNodesHandler

A decorator for handlers which ensures that all blank nodes get unique IDs even if a blank node identifier is reused.

Namespace: VDS.RDF.Parsing.Handlers
Assembly: dotNetRDF.dll
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.
