Constructor & Destructor Documentation

◆ AbsBnd() [1/2]

template<class View>
Gecode::Int::Arithmetic::AbsBnd< View >::AbsBnd ( Space & home,
AbsBnd< View > & p )
protected

Constructor for cloning p.

◆ AbsBnd() [2/2]

template<class View>
Gecode::Int::Arithmetic::AbsBnd< View >::AbsBnd ( Home home,
View x0,
View x1 )
inlineprotected

Constructor for posting.

Definition at line 88 of file abs.hpp.

Member Function Documentation

◆ copy()

template<class View>
Actor * Gecode::Int::Arithmetic::AbsBnd< View >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 120 of file abs.hpp.

◆ cost()

template<class View>
PropCost Gecode::Int::Arithmetic::AbsBnd< View >::cost ( const Space & home,
const ModEventDelta & med ) const
virtual

Cost function.

If a view has been assigned, the cost is low unary. Otherwise it is low binary.

Reimplemented from Gecode::BinaryPropagator< View, PC_INT_BND >.

Definition at line 126 of file abs.hpp.

◆ propagate()

template<class View>
ExecStatus Gecode::Int::Arithmetic::AbsBnd< View >::propagate ( Space & home,
const ModEventDelta & med )
virtual

Perform propagation.

Implements Gecode::Propagator.

Definition at line 135 of file abs.hpp.

◆ post()

template<class View>
ExecStatus Gecode::Int::Arithmetic::AbsBnd< View >::post ( Home home,
View x0,
View x1 )
static

Post bounds consistent propagator $ |x_0|=x_1$.

Definition at line 93 of file abs.hpp.
