public class PropagationBaseObject
extends BaseObject
NOLINT
The PropagationBaseObject is a subclass of BaseObject that is also
friend to the Solver class. It allows accessing methods useful when
writing new constraints or new expressions.

  • Constructor Details

    • PropagationBaseObject

      protected PropagationBaseObject​(long cPtr, boolean cMemoryOwn)

    • PropagationBaseObject

      public PropagationBaseObject​(Solver s)

  • Method Details

    • getCPtr

      protected static long getCPtr​(PropagationBaseObject obj)

    • finalize

      protected void finalize()
      Overrides:
      finalize in class BaseObject

    • delete

      public void delete()
      Overrides:
      delete in class BaseObject

    • toString

      public java.lang.String toString()
      Overrides:
      toString in class BaseObject

    • solver

      public Solver solver()

    • freezeQueue

      public void freezeQueue()
      This method freezes the propagation queue. It is useful when you
      need to apply multiple modifications at once.

    • unfreezeQueue

      public void unfreezeQueue()
      This method unfreezes the propagation queue. All modifications
      that happened when the queue was frozen will be processed.

    • enqueueDelayedDemon

      public void enqueueDelayedDemon​(Demon d)
      This method pushes the demon onto the propagation queue. It will
      be processed directly if the queue is empty. It will be enqueued
      according to its priority otherwise.

    • enqueueVar

      public void enqueueVar​(Demon d)

    • reset_action_on_fail

      public void reset_action_on_fail()
      This method clears the failure callback.

    • set_variable_to_clean_on_fail

      public void set_variable_to_clean_on_fail​(IntVar v)
      Shortcut for variable cleaner.

    • name

      public java.lang.String name()
      Object naming.

    • setName

      public void setName​(java.lang.String name)

    • hasName

      public boolean hasName()
      Returns whether the object has been named or not.

    • baseName

      public java.lang.String baseName()
      Returns a base name for automatic naming.
