Constructor & Destructor Documentation

Gecode::Action::Action

(

void

)

[inline]

Construct as not yet intialized.

The only member functions that can be used on a constructed but not yet initialized action storage is init and the assignment operator.

Definition at line 323 of file action.hpp.

Gecode::Action::Action

(

const Action &

a

)

Copy constructor.

Definition at line 46 of file action.cpp.

template<class View >

Gecode::Action::Action	(	Home	home,
		ViewArray< View > &	x,
		double	d,
		typename BranchTraits< typename View::VarType >::Merit	bm
	)			[inline]

Initialize for views x and decay factor d and action as defined by bm.

Definition at line 327 of file action.hpp.

Gecode::Action::~Action

(

void

)

Destructor.

Definition at line 55 of file action.cpp.
