bool Gecode::VarViewBase< VarImp >::varderived

(

void

)

[inline, static]

Return whether this view is derived from a VarViewBase.

template<class VarImp >

VarImp * Gecode::VarViewBase< VarImp >::var

(

void

)

const [inline]

Return variable implementation of view.

Definition at line 291 of file view.hpp.

template<class VarImp >

unsigned int Gecode::VarViewBase< VarImp >::degree

(

void

)

const [inline]

Return degree (number of subscribed propagators and advisors).

Definition at line 296 of file view.hpp.

template<class VarImp >

double Gecode::VarViewBase< VarImp >::afc

(

void

)

const [inline]

Return accumulated failure count (plus degree).

Definition at line 301 of file view.hpp.

template<class VarImp >

void Gecode::VarViewBase< VarImp >::schedule	(	Space &	home,
		Propagator &	p,
		ModEvent	me
	)			[inline, static]

Schedule propagator p with modification event me.

Definition at line 327 of file view.hpp.

template<class VarImp >

ModEvent Gecode::VarViewBase< VarImp >::me

(

const ModEventDelta &

med

)

[inline, static]

Return modification event for view type in med.

Definition at line 332 of file view.hpp.

template<class VarImp >

ModEventDelta Gecode::VarViewBase< VarImp >::med

(

ModEvent

me

)

[inline, static]

Translate modification event me to modification event delta for view.

Reimplemented in Gecode::Int::IntView, and Gecode::Int::BoolView.

Definition at line 337 of file view.hpp.

template<class VarImp >

ModEvent Gecode::VarViewBase< VarImp >::me_combine	(	ModEvent	me1,
		ModEvent	me2
	)			[inline, static]

Combine modifications events me1 and me2.

Definition at line 342 of file view.hpp.

template<class VarImp >

void Gecode::VarViewBase< VarImp >::subscribe	(	Space &	home,
		Propagator &	p,
		PropCond	pc,
		bool	process = true
	)			[inline]

Subscribe propagator p with propagation condition pc to view.

In case process is false, the propagator is just subscribed but not processed for execution (this must be used when creating subscriptions during propagation).

Definition at line 306 of file view.hpp.

		Advisor &	a
	)			[inline]

Subscribe advisor a to view.

Definition at line 317 of file view.hpp.

void Gecode::VarViewBase< VarImp >::cancel	(	Space &	home,
		Advisor &	a
	)			[inline]

Cancel subscription of advisor a.
