Member Function Documentation

◆ copy()

template<class SView , class RView >
Actor * Gecode::Set::Element::ElementUnionConst< SView, RView >::copy ( Space & home)
virtual

Copy propagator during cloning.

Implements Gecode::Actor.

Definition at line 109 of file unionConst.hpp.

◆ cost()

template<class SView , class RView >
PropCost Gecode::Set::Element::ElementUnionConst< SView, RView >::cost ( const Space & home,
const ModEventDelta & med ) const
virtual

Cost function.

Implements Gecode::Propagator.

Definition at line 67 of file unionConst.hpp.

◆ reschedule()

template<class SView , class RView >
void Gecode::Set::Element::ElementUnionConst< SView, RView >::reschedule ( Space & home)
virtual

Schedule function.

Implements Gecode::Propagator.

Definition at line 73 of file unionConst.hpp.

◆ dispose()

template<class SView , class RView >
size_t Gecode::Set::Element::ElementUnionConst< SView, RView >::dispose ( Space & home)
inlinevirtual

Delete propagator and return its size.

Reimplemented from Gecode::Actor.

Definition at line 80 of file unionConst.hpp.

◆ propagate()

template<class SView , class RView >
ExecStatus Gecode::Set::Element::ElementUnionConst< SView, RView >::propagate ( Space & home,
const ModEventDelta & med )
virtual

Perform propagation.

Implements Gecode::Propagator.

Definition at line 115 of file unionConst.hpp.

◆ post()

template<class SView , class RView >
ExecStatus Gecode::Set::Element::ElementUnionConst< SView, RView >::post ( Home home,
SView z,
const IntSetArgs & x,
RView y )
static

Post propagator for $ z=\bigcup\langle s_0,\dots,s_{n-1}\rangle[y] $

If y is empty, z will be constrained to be empty (as an empty union is the empty set).
