Template Parameters

D	number of cartesian dimensions

Constructor & Destructor Documentation

◆ ComponentView() [1/2]

template<typename T , int D>

ThunderEgg::ComponentView< T, D >::ComponentView	(	T_ptr	data,

	)

inline

Construct a new View object.

Parameters

data	pointer to the first element in the patch (non-ghost cell element)
strides	the strides in each direction
lengths	the lengths in each direction
num_ghost_cells	the number of ghost cells on each side of the patch
ldm	the local data manager for the data

◆ ComponentView() [2/2]

template<typename T , int D>

		const std::array< int, D > &	strides,
		const std::array< int, D > &	lengths,
		int	num_ghost_cells
	)

inline

Construct a new View object.

Parameters

data	pointer to the first element in the patch (non-ghost cell element)
strides	the strides in each direction
lengths	the lengths in each direction
num_ghost_cells	the number of ghost cells on each side of the patch

◆ getGhostSliceOn()

template<typename T , int D>

template<int M>

template View< double, 2 > ThunderEgg::ComponentView< T, D >::getGhostSliceOn	(	Face< D, M >	f,
		const std::array< size_t, D - M > &	offset
	)		const

inline

Get the gosts slice on a given face.

Template Parameters

M	the dimension of the face

Parameters

f	the face
offset	offset the offset of the value {0,..,0} first ghost cell slice touching that face face

Returns: View<M> a view to the slice on the face

◆ getSliceOn()

template<typename T , int D>

template<int M>

template View< const double, 2 > ThunderEgg::ComponentView< T, D >::getSliceOn	(	Face< D, M >	f,
		const std::array< int, D - M > &	offset
	)		const

inline

Get the slice on a given face.

Template Parameters

M	the dimension of the face

Parameters

f	the face
offset	offset the offset of the value {0,..,0} is the non ghost cell touching the face. {-1,..,-1} is the first ghost cell touching that face

Returns: View<M> a view to the slice on the face
