  • Method Details

    • find

      public ExtendedIterator<Triple> find(TriplePattern pattern)
      Basic pattern lookup interface.
      Specified by:
      find in interface Finder
      Parameters:
      pattern - a TriplePattern to be matched against the data
      Returns:
      a ClosableIterator over all Triples in the data set that match the pattern

    • findWithContinuation

      public ExtendedIterator<Triple> findWithContinuation(TriplePattern pattern, Finder continuation)
      Extended find interface used in situations where the implementator may or may not be able to answer the complete query. It will attempt to answer the pattern but if its answers are not known to be complete then it will also pass the request on to the nested Finder to append more results.
      Specified by:
      findWithContinuation in interface Finder
      Parameters:
      pattern - a TriplePattern to be matched against the data
      continuation - either a Finder or a normal Graph which will be asked for additional match results if the implementor may not have completely satisfied the query.

    • getGraph

      public Graph getGraph()
      Returns the graph.
      Returns:
      Graph

    • contains

      public boolean contains(TriplePattern pattern)
      Return true if the given pattern occurs somewhere in the find sequence.
      Specified by:
      contains in interface Finder
