  • Method Details

    • getAllWritableData

      Map<Predicate, W> getAllWritableData()
      Get all the writable data by Predicate
      Returns:
      a map from predicates to the writable data

    • getDefaultWritableData

      Optional<W> getDefaultWritableData()
      Get the default-writable data, if provided The default-writable data is where atoms are written if they have a predicate not assigned to a writable
      Returns:
      an optional, containing the default writable, if provided

    • getWritable

      default Optional<W> getWritable(Predicate predicate)
      Get a writable by predicate Return the writable bind to a predicate or, if the predicate is not bound to a writable, the default writable
      Parameters:
      predicate - the predicate for which we want to get the writable data
      Returns:
      an optional containing the writable bound to a predicate or the default writable if available

      true iff the atom is new

    • remove

      default boolean remove(Atom atom)
      Description copied from interface: Writable
      Removes the given atom
      Specified by:
      remove in interface Writable
      Parameters:

      Returns:
      true iff the atom is removed

    • clear

      default void clear()
      Description copied from interface: Writable
      Deletes all atoms
      Specified by:
      clear in interface Writable
