Class PropagationBaseObject

java.lang.Object
com.google.ortools.constraintsolver.BaseObject
com.google.ortools.constraintsolver.PropagationBaseObject
Direct Known Subclasses:
Assignment, Constraint, IntervalVar, IntExpr, SequenceVar
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.

    • PropagationBaseObject

      public PropagationBaseObject(Solver s)

  • Method Details

    • getCPtr

      public static long getCPtr(PropagationBaseObject obj)

    • swigRelease

      public static long swigRelease(PropagationBaseObject obj)

    • finalize

      protected void finalize()
      Overrides:
      finalize in class BaseObject

    • delete

      public void delete()
      Overrides:
      delete in class BaseObject

    • toString

      public 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 String name()
      Object naming.

    • setName

      public void setName(String name)

    • hasName

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

    • baseName

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