Syntax

public class RdfAPatternCopyingHandler : IWrappingRdfHandler, IRdfHandler, INodeFactory

Remarks

This streaming implementation will only capture pattern triples that are emitted after declaration of the rdfa:Pattern type for the pattern resource is encountered or after an rdfa:copy triple with the pattern as its object is encountered.
