    • declarePending

      public boolean declarePending(org.apache.jena.rdf.model.RDFNode node)
      Description copied from interface: HashIdCxt
      Declare traversal of a node. Traversal is the search for nodes subject to processing. A node may be declared as traversed any number of times - in contrast to declareProcessing which may only be invoked once on an unprocessed node.
      Specified by:
      declarePending in interface HashIdCxt
      Returns:

    • isPending

      public boolean isPending(org.apache.jena.rdf.model.RDFNode node)
