Detailed Description

template<int Dim, typename CellProperty = cell_property<Dim>, typename FaceProperty = face_property<Dim>>
class stapl::unstructured_mesh< Dim, CellProperty, FaceProperty >

Implementation of n-dimensional unstructured mesh. Inherits from stapl::dynamic_graph and adds functionality to manage cells, faces and mesh vertices.

Template Parameters

CellProperty	type of property for the mesh cell. Default is cell_property.
FaceProperty	type of property for the mesh face. Default is face_property.

Constructor & Destructor Documentation

unstructured_mesh() [1/2]

template<int Dim, typename CellProperty = cell_property<Dim>, typename FaceProperty = face_property<Dim>>

template<typename Generator >

stapl::unstructured_mesh< Dim, CellProperty, FaceProperty >::unstructured_mesh

(

Generator

gen

)

Contructor taking a mesh generator.

Parameters

gen	mesh generator.

unstructured_mesh() [2/2]

template<int Dim, typename CellProperty = cell_property<Dim>, typename FaceProperty = face_property<Dim>>

stapl::unstructured_mesh< Dim, CellProperty, FaceProperty >::unstructured_mesh

(

size_t const &

num_mesh_vertices

)

Constructor initializing the size of the array of vertices.

Parameters

num_mesh_vertices

number of vertices of the mesh.

Note

here "vertex" means a geometric vertex of a mesh cell and a graph vertex represents a mesh cell.

Member Function Documentation

set_mesh_vertex()

template<int Dim, typename CellProperty = cell_property<Dim>, typename FaceProperty = face_property<Dim>>

void stapl::unstructured_mesh< Dim, CellProperty, FaceProperty >::set_mesh_vertex	(	index_type const &	idx,
		geom_vector_type const &	val
	)

Set the coordinates of a cell vertex.

Parameters

idx	cell vertex identifier.
val	geometric vector representing the coordinates of the cell vertex.

add_cell_face_async()

template<int Dim, typename CellProperty = cell_property<Dim>, typename FaceProperty = face_property<Dim>>

void stapl::unstructured_mesh< Dim, CellProperty, FaceProperty >::add_cell_face_async	(	edge_descriptor const &	ed,
		vid_sequence_type const &	vertex_ids = vid_sequence_type()
	)

Add a cell face asynchronously.

Parameters

ed	face descriptor.
vertex_ids	sequence of vertices of the cell face.

get_vertex_array()

template<int Dim, typename CellProperty = cell_property<Dim>, typename FaceProperty = face_property<Dim>>

vertex_array_type* stapl::unstructured_mesh< Dim, CellProperty, FaceProperty >::get_vertex_array

(

)

Returns a pointer on the pArray storing the mesh vertices.

Returns

pointer over pArray of vertices.

domain()

domain_type stapl::dynamic_graph< D, M, OptionalParams >::domain ( ) const

inherited

Returns an iterator_domain of this pGraph.

Returns

iterator_domain over the pGraph.

add_vertex() [1/4]

vertex_descriptor stapl::dynamic_graph< D, M, OptionalParams >::add_vertex ( void  )

inherited

Adds a vertex to the pGraph with a default-constructed property.

Returns

vertex_descriptor of the added vertex.

Vertex-descriptor is assigned automatically by the pGraph. This method is asynchronous. The vertex is added at the calling location, which is also the home location for the vertex.

add_vertex() [2/4]

vertex_descriptor stapl::dynamic_graph< D, M, OptionalParams >::add_vertex ( vertex_property const &  vp )

inherited

Adds a vertex to the pGraph with the given property.

Parameters

vp	Property of the vertex.

Returns

vertex_descriptor of the added vertex.

Vertex-descriptor is assigned automatically by the pGraph. This method is asynchronous. The vertex is added at the calling location, which is also the home location for the vertex.

add_vertex() [3/4]

vertex_descriptor stapl::dynamic_graph< D, M, OptionalParams >::add_vertex ( vertex_descriptor const &  gid, vertex_property const &  vp  )

inherited

Adds a vertex to the pGraph with the given property and descriptor.

Parameters

gid	descriptor of the vertex.
vp	Property of the vertex.

Returns

vertex_descriptor of the added vertex.

This method is asynchronous. The vertex is added at the calling location. An async is sent to the home-location of the vertex.

add_vertex() [4/4]

void stapl::dynamic_graph< D, M, OptionalParams >::add_vertex ( vertex_descriptor const &  gid, vertex_property const &  vp, Functor const &  f  )

inherited

Adds a vertex to the pGraph with the given property and descriptor, if the vertex does not exist, or applies the given functor to the existing vertex. The vertex is added to the home location, unlike the other add_vertex calls that add the vertex at the current location.

Parameters

gid	descriptor of the vertex.
vp	Property of the vertex.
f	Function to apply to the vertex if it already exists.

This method is asynchronous. The vertex is added at the home-location.

add_vertex_uniform()

vertex_descriptor stapl::dynamic_graph< D, M, OptionalParams >::add_vertex_uniform ( vertex_property const &  vp )

inherited

Adds a vertex to the pGraph with the given property to a location based on the vertex descriptor assigned by the graph. This method is asynchronous. This method differs from the typical add_vertex as it inserts the vertex into a potentially remote location, rather than the calling location.

Parameters

vp	Property of the vertex.

Returns

vertex_descriptor of the added vertex.

delete_vertex()

void stapl::dynamic_graph< D, M, OptionalParams >::delete_vertex ( vertex_descriptor const &  gid )

inherited

Deletes a vertex from the pGraph with the given descriptor. This method is asynchronous.

Parameters

gid	descriptor of the vertex.
