Detailed Description

template<int dim, typename Number>
class internal::MatrixFreeFunctions::ConstraintInfo< dim, Number >

A helper class to apply constraints in matrix-free loops in user code. It combines constraint related functionalties from MatrixFree and FEEvaluation.

◆ reinit() [1/2]

template<int dim, typename Number >
void internal::MatrixFreeFunctions::ConstraintInfo< dim, Number >::reinit ( const DoFHandler< dim > &  dof_handler,
const unsigned int  n_cells,
const bool  use_fast_hanging_node_algorithm = true 
)
