Member Function Documentation

◆ Accept()

void Accept ( ModelVisitor *const  visitor) const
inlineoverridevirtual

Accepts the given visitor.

Reimplemented from Constraint.

Definition at line 1174 of file element.cc.

◆ BaseName()

std::string BaseName ( ) const
virtualinherited

Returns a base name for automatic naming.

Reimplemented in BooleanVar.

Definition at line 2515 of file constraint_solver.cc.

◆ DebugString()

std::string DebugString ( ) const
inlineoverridevirtual

Reimplemented from Constraint.

Definition at line 1168 of file element.cc.

◆ EnqueueAll()

void EnqueueAll ( const SimpleRevFIFO< Demon * > &  demons)
inherited

Definition at line 2521 of file constraint_solver.cc.

◆ EnqueueDelayedDemon()

void EnqueueDelayedDemon ( Demon *const  d)
inlineinherited

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.

Definition at line 3192 of file constraint_solver.h.

◆ EnqueueVar()

void EnqueueVar ( Demon *const  d)
inlineinherited

Definition at line 3193 of file constraint_solver.h.

◆ ExecuteAll()

void ExecuteAll ( const SimpleRevFIFO< Demon * > &  demons)
inherited

Definition at line 2517 of file constraint_solver.cc.

◆ FreezeQueue()

void FreezeQueue ( )
inlineinherited

This method freezes the propagation queue.

It is useful when you need to apply multiple modifications at once.

Definition at line 3183 of file constraint_solver.h.

◆ HasName()

bool HasName ( ) const
inherited

Returns whether the object has been named or not.

Definition at line 2513 of file constraint_solver.cc.

◆ InitialPropagate()

void InitialPropagate ( )
inlineoverridevirtual

This method performs the initial propagation of the constraint.

It is called just after the post.

Implements Constraint.

Definition at line 1133 of file element.cc.

◆ IsCastConstraint()

bool IsCastConstraint ( ) const
inherited

Is the constraint created by a cast from expression to integer variable?

Definition at line 3253 of file constraint_solver.cc.

◆ name()

std::string name ( ) const
virtualinherited

Object naming.

Reimplemented in PiecewiseLinearExpr.

Definition at line 2505 of file constraint_solver.cc.

◆ Post()

void Post ( )
inlineoverridevirtual

This method is called when the constraint is processed by the solver.

Its main usage is to attach demons to variables.

Implements Constraint.

Definition at line 1125 of file element.cc.

◆ PostAndPropagate()

void PostAndPropagate ( )
inherited

Calls Post and then Propagate to initialize the constraints.

This is usually done in the root node.

Definition at line 3239 of file constraint_solver.cc.

◆ reset_action_on_fail()

void reset_action_on_fail ( )
inlineinherited

This method clears the failure callback.

Definition at line 3206 of file constraint_solver.h.

◆ set_action_on_fail()

void set_action_on_fail ( Solver::Action  a)
inlineinherited

Definition at line 3200 of file constraint_solver.h.

◆ set_name()

void set_name ( const std::string &  name)
inherited

Definition at line 2509 of file constraint_solver.cc.

◆ set_variable_to_clean_on_fail()

void set_variable_to_clean_on_fail ( IntVar v)
inlineinherited

Shortcut for variable cleaner.

Definition at line 3209 of file constraint_solver.h.

◆ solver()

Solver * solver ( ) const
inlineinherited

Definition at line 3179 of file constraint_solver.h.

◆ target_var()

IntVar * target_var ( ) const
inlineinherited

Definition at line 3628 of file constraint_solver.h.

◆ UnfreezeQueue()

void UnfreezeQueue ( )
inlineinherited

This method unfreezes the propagation queue.

All modifications that happened when the queue was frozen will be processed.

Definition at line 3187 of file constraint_solver.h.

◆ Var()

IntVar * Var ( )
virtualinherited

Creates a Boolean variable representing the status of the constraint (false = constraint is violated, true = constraint is satisfied).

It returns nullptr if the constraint does not support this API.

Definition at line 3257 of file constraint_solver.cc.
