  • Method Details

    • acceptNode

      void acceptNode(String sFunctor, NodeTerm term)
      The receiver has been dispatched to from the given node.
      Parameters:
      sFunctor - the node functor
      term - the NodeTerm

    • acceptAtom

      void acceptAtom(String sFunctor, AtomicTerm atomicTerm)
      The receiver has been dispatched to from the given atom.
      Parameters:
      sFunctor - the node functor
      atomicTerm - the AtomicTerm

    • acceptTerm

      void acceptTerm(String sFunctor, Term term)
      The receiver has been dispatched to from the given atom.
      Parameters:
      sFunctor - the node functor
      term - the Term

    • getResult

      Object getResult()
      Return the result of the previous TermTree walk. This value could be null if no trees have been walked or the last tree walk resulted in an undetermined state.
      Returns:
      the result of the previous TermTree walk

    • walk

      Object walk(Term term)
      Return the result of the walking the specified TermTree. This value could be null if the tree walk results in an undetermined state.
      Parameters:
      term - the term tree to walk to obtain a result object
      Returns:
      the result of walking the specified TermTree
