util_intops::TwoLevelsView< Lvl1ViewT, EnableVectorT > Class Template Reference

Detailed Description

template<typename Lvl1ViewT, typename EnableVectorT>
class util_intops::TwoLevelsView< Lvl1ViewT, EnableVectorT >

This view provides a mechanism to access and filter elements in a 2D container. The filtering is applied in two stages:

  1. The first dimension is generic and can be both and index-list or bool-vector based view.
  2. The second dimension (items of each sub-container) is further filtered using a boolean-vector-like object, which determines which elements within the sub-container are included in the view.
