walberla::selectable::AllSetSelectableObject< T, U > Class Template Reference

Detailed Description

template<typename T, typename U>
class walberla::selectable::AllSetSelectableObject< T, U >

Implementation of SelectableObject using sets (see "AllSet.h") as selection attributes.

AllSetSelectableObject is an implementation of SelectableObject that stores objects of type T which are attached with selection attributes of type AllSet<U>. For information on which objects are selected given a certain set as selection request see the documentation of the function "select".

virtual void	select (std::vector< size_t > &index, const AllSet< U > &selector) const
	Given a certain selection request 'R' (= "selector" [set of objects of type U]), this function returns the index 'i' of every attribute set 'A_i' (A_0 <=> attributes_[0], A_1 <=> attributes_[1], etc.) that matches the request 'R'.

template<typename T, typename U>

void walberla::selectable::AllSetSelectableObject< T, U >::select ( std::vector< size_t > & index, const AllSet< U > & selector ) const

privatevirtual

Given a certain selection request 'R' (= "selector" [set of objects of type U]), this function returns the index 'i' of every attribute set 'A_i' (A_0 <=> attributes_[0], A_1 <=> attributes_[1], etc.) that matches the request 'R'.

Possible candidates are:

• for "normal" sets: sets 'A_i' that are completely contained within the set 'R'
• for "all" sets (see "AllSet.h"): sets 'A_i' that completely contain the set 'R' Out of these possible candidates, the set A_x that contains most elements is chosen. Additionally, out of these candidates, every set that contains as many elements as A_x and every set that contains as many or even more elements than the selection request 'R' is also chosen.

Implements walberla::selectable::SelectableObject< T, AllSet< U >, AllSet< U > >.
