Detailed Description

template<class local_matrix_type, class functor_type, class... remaining_functor_types>
class MueLu::MatrixConstruction::VectorCountingFunctor< local_matrix_type, functor_type, remaining_functor_types >

Functor that executes a sequence of sub-functors on each block of rows.

The functor applies a series of functors to each row of the matrix. Each sub-functor can modify the decision to drop or keep any matrix entry in the given row. These decisions are applied to the results_view. Once a row has been processed by all sub-functors, the number of entries in the row after dropping is determined. The result is saved as offsets in rowptr.
