void Gecode::VarImpView< Var >::schedule ( Space home,
Propagator p,
ModEvent  me 
) [inline, static]

Schedule propagator p with modification event me.

Definition at line 509 of file view.hpp.

template<class Var >
ModEvent Gecode::VarImpView< Var >::me ( const ModEventDelta med  )  [inline, static]
