virtual

Schedule function.

Implements Gecode::Propagator.

Definition at line 68 of file union.hpp.

◆ dispose()

template<class View, class View0, class View1>
size_t Gecode::Set::Element::ElementUnion< View, View0, View1 >::dispose ( Space & home)
inlinevirtual

Delete propagator and return its size.

Reimplemented from Gecode::Actor.

Definition at line 76 of file union.hpp.

◆ propagate()

template<class View, class View0, class View1>
ExecStatus Gecode::Set::Element::ElementUnion< View, View0, View1 >::propagate ( Space & home,

ExecStatus Gecode::Set::Element::ElementUnion< View, View0, View1 >::post ( Home home,
IdxViewArray & x,
View0 y,
View1 z )
static

Post propagator for $ z=\bigcup\langle x_0,\dots,x_{n-1}\rangle[y] $

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