void Gecode::VarImpView< Var >::varimp

(

VarImpType *

y

)

[inline, protected]

Set variable implementation to y.

Definition at line 484 of file view.hpp.

template<class Var >

bool Gecode::VarImpView< Var >::varderived

(

bool Gecode::VarImpView< Var >::assigned

(

void

)

const [inline]

Test whether view is assigned.

Definition at line 516 of file view.hpp.

template<class Var >

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

Schedule propagator p with modification event me.
