◆ NaryEq() [1/2]

template<class View >
Gecode::Float::Rel::NaryEq< View >::NaryEq ( Space & home,
NaryEq< View > & p )
inlineprotected

Constructor for cloning p.

Definition at line 141 of file eq.hpp.

◆ NaryEq() [2/2]

template<class View >
Gecode::Float::Rel::NaryEq< View >::NaryEq ( Home home,
ViewArray< View > & x )

Member Function Documentation

◆ copy()

template<class View >
Actor * Gecode::Float::Rel::NaryEq< View >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 146 of file eq.hpp.

◆ cost()

template<class View >
PropCost Gecode::Float::Rel::NaryEq< 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 linear.

Reimplemented from Gecode::NaryPropagator< View, PC_FLOAT_BND >.

Definition at line 152 of file eq.hpp.

◆ propagate()

template<class View >
ExecStatus Gecode::Float::Rel::NaryEq< View >::propagate ( Space & home,
const ModEventDelta & med )
virtual

Perform propagation.

Implements Gecode::Propagator.

Definition at line 161 of file eq.hpp.

◆ post()

template<class View >
ExecStatus Gecode::Float::Rel::NaryEq< View >::post ( Home home,
ViewArray< View > & x )
static

Post bounds consistent propagator $ x_0 = x_1=\ldots =x_{|x|-1}$.

Definition at line 119 of file eq.hpp.
