Detailed Description

template<class View, class Offset, bool shared>
class Gecode::Int::Channel::Dom< View, Offset, shared >

Domain consistent channel propagator.

If shared is true, the same views can be contained in both x and y.

template<class View, class Offset, bool shared>
Gecode::Int::Channel::Dom< View, Offset, shared >::Dom ( Space home,
Dom< View, Offset, shared > &  p 
)
protected

Constructor for cloning p.

◆ Dom() [2/2]

template<class View , class Offset , bool shared>
Gecode::Int::Channel::Dom< View, Offset, shared >::Dom ( Home  home,
int  n,
DomInfo< View, Offset > *  xy,

Member Function Documentation

◆ copy()

template<class View , class Offset , bool shared>
Actor * Gecode::Int::Channel::Dom< View, Offset, shared >::copy ( Space home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 180 of file dom.hpp.

◆ cost()

template<class View , class Offset , bool shared>
PropCost Gecode::Int::Channel::Dom< View, Offset, shared >::cost ( const Space home,
const ModEventDelta med 
) const
virtual

Cost function.

If in stage for naive value propagation, the cost is low quadratic. Otherwise it is high quadratic.

Reimplemented from Gecode::Int::Channel::Base< DomInfo< View, Offset >, Offset, PC_INT_DOM >.

Definition at line 186 of file dom.hpp.

◆ propagate()

template<class View , class Offset , bool shared>
ExecStatus Gecode::Int::Channel::Dom< View, Offset, shared >::propagate ( Space home,
const ModEventDelta med 
)
virtual

Perform propagation.

Implements Gecode::Propagator.

Definition at line 196 of file dom.hpp.

◆ post()

template<class View , class Offset , bool shared>
ExecStatus Gecode::Int::Channel::Dom< View, Offset, shared >::post ( Home  home,
int  n,
DomInfo< View, Offset > *  xy,
Offset ox,
Offset oy 
)
static

Post propagator for channeling on xy.

Definition at line 305 of file dom.hpp.
