Class MultiHandler
A Handler which passes the RDF to be handled to multiple Handlers where Handling terminates in the handling request where one of the Handlers returns false.
Inherited Members
Namespace: VDS.RDF.Parsing.Handlers
Assembly: dotNetRdf.dll
Syntax
public class MultiHandler : BaseRdfHandler, ICommentRdfHandler, IWrappingRdfHandler, IRdfHandler, INodeFactory
Remarks
This differs from ChainedHandler in that even if one Handler indicates that handling should stop by returning false all the Handlers still have a chance to handle the Base URI/Namespace/Triple before handling is terminated. All Handlers will always have their StartRdf and EndRdf methods called.
