Constructor & Destructor Documentation

Array() [1/2]

template<class Scalar, class EntityType, class MeshType, class... Params>

Cabana::Grid::Array< Scalar, EntityType, MeshType, Params >::Array ( const std::string & label, const std::shared_ptr< array_layout > & layout )

inline

Create an array with the given layout. Arrays are constructed over the ghosted index space of the layout.

Parameters

label	A label for the array.
layout	The array layout over which to construct the view.

Array() [2/2]

template<class Scalar, class EntityType, class MeshType, class... Params>

Cabana::Grid::Array< Scalar, EntityType, MeshType, Params >::Array ( const std::shared_ptr< array_layout > & layout, const view_type & view )

inline

Create an array with the given layout and view. This view should match the array index spaces in size.

Parameters

layout	The layout of the array.
view	The array data.
