Member Function Documentation

◆ appendWeight()

template<typename weight_t, typename value_t>

void bitpit::MPDiscreteStencil< weight_t, value_t >::appendWeight ( const weight_t & weight )

overrideprotectedvirtual

Append a weight to the stencil.

Parameters

weight is the weight that will be appended

Reimplemented from bitpit::DiscreteStencil< weight_t, value_t >.

Definition at line 1028 of file stencil.tpp.

◆ clearWeights()

template<typename weight_t, typename value_t>

void bitpit::MPDiscreteStencil< weight_t, value_t >::clearWeights ( bool release )

overrideprotectedvirtual

Clears the weights of the stencil.

Removes all weights from the stencil (which are destroyed), leaving the weight container with a size of 0.

Parameters

release if it's true the memory hold by the weight container will be released, otherwise the weight container will be cleared but its memory will not be relased

Reimplemented from bitpit::DiscreteStencil< weight_t, value_t >.

Definition at line 1049 of file stencil.tpp.

◆ setWeightPool()

template<typename weight_t, typename value_t = typename DiscreteStencilWeightValueInfo<weight_t>::type>

void bitpit::MPDiscreteStencil< weight_t, value_t >::setWeightPool ( weight_pool_type * pool )

Set the weight pool.

Parameters

pool	is the weight pool that will be used
