Initialize with variable implementation y.

Definition at line 480 of file view.hpp.

Member Function Documentation

template<class Var >

void Gecode::VarImpView< Var >::varimp ( VarImpType * y ) [inline, protected]

Set variable implementation to y.

Definition at line 484 of file view.hpp.

Definition at line 504 of file view.hpp.

template<class Var >

bool Gecode::VarImpView< Var >::assigned ( void ) const [inline]

		Propagator &	p,
		ModEvent	me
	)			`[inline, static]`

Schedule propagator p with modification event me.

Definition at line 547 of file view.hpp.

template<class Var >

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

Return modification event for view type in med.
