    • executeAfterConsistency

      public boolean executeAfterConsistency(boolean consistent)
      Description copied from interface: ConsistencyListener
      It is executed right after consistency of the current search node. Returning true when the parameter was false is not advised as things like invalid solutions can be found.
      Specified by:
      executeAfterConsistency in interface ConsistencyListener
      Parameters:
      consistent - specifies if the consistency call returned true or false.
      Returns:
      true if the search should continue, false if the search should act as the consistency returned false.

    • setChildrenListeners

      Description copied from interface: ConsistencyListener
      Each of the child listeners will be called and the return code from them will be combined (taken into account) by a parent).
      Specified by:
      setChildrenListeners in interface ConsistencyListener
      Parameters:
      children - the children listeners attached to this listener.

    • setChildrenListeners

      public void setChildrenListeners(ConsistencyListener child)
      Description copied from interface: ConsistencyListener
      Setting one child listener.
      Specified by:
      setChildrenListeners in interface ConsistencyListener
      Parameters:
      child - the only child listener added to this consistency listener.
