Detailed Description

template<int dim, int n_components, typename value_type_>
class internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >

A class helps to access PecomputedEvaluationData in a thread-safe manner. Each thread has to create this wrapper class on its own to avoid race-conditions during reinit().

get_value()

template<int dim, int n_components, typename value_type_ >

const PrecomputedEvaluationData< dim, n_components, value_type_ >::value_type internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >::get_value

(

const unsigned int

q

)

const

Get the value at quadrature point q. The entity on which the values are defined is set via reinit().

Parameters

[in]

q

Quadrature point at which the value is queried.

Definition at line 692 of file fe_remote_evaluation.h.

get_gradient()

template<int dim, int n_components, typename value_type_ >

const PrecomputedEvaluationData< dim, n_components, value_type_ >::gradient_type internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >::get_gradient

(

const unsigned int

q

)

const

Get the gradients at quadrature point q. The entity on which the gradients are defined is set via reinit().

Parameters

[in]

q

Quadrature point at which the gradient is queried.

Definition at line 704 of file fe_remote_evaluation.h.

reinit() [1/2]

template<int dim, int n_components, typename value_type_ >

void internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >::reinit

(

const unsigned int

index

)

This function has to be called before get_value() and/or get_gradient().

Parameters

[in]

index

Entity index at which quadrature points are accessed. This can be, e.g., a cell index, a cell batch index, or a face batch index.

Definition at line 715 of file fe_remote_evaluation.h.

reinit() [2/2]

template<int dim, int n_components, typename value_type_ >

void internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >::reinit	(	const unsigned int	index_0,
		const unsigned int	index_1 )

Set cell and face number at which quadrature points are accessed.

Parameters

[in]	index_0	cell index.
[in]	index_1	cell-local face number.

Member Data Documentation

view

template<int dim, int n_components, typename value_type_ >

const PrecomputedEvaluationDataView& internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >::view

private

PrecomputedEvaluationDataView provides information where values are located.

Definition at line 173 of file fe_remote_evaluation.h.

data

template<int dim, int n_components, typename value_type_ >

const PrecomputedEvaluationData<dim, n_components, value_type_>& internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >::data

private

Definition at line 178 of file fe_remote_evaluation.h.

data_offset

template<int dim, int n_components, typename value_type_ >

unsigned int internal::PrecomputedEvaluationDataAccessor< dim, n_components, value_type_ >::data_offset

private

Offset to data after last call of reinit().
