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.

Constructor Detail

PropagationBaseObject

protected PropagationBaseObject(long cPtr,
                                boolean cMemoryOwn)

PropagationBaseObject

public PropagationBaseObject(Solver s)

Method Detail

getCPtr

protected static long getCPtr(PropagationBaseObject obj)

swigRelease

protected 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 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.
