Detailed Description

Adjacency data is formated as a sequence of integer groups where the first entry in each group is the ID of the element for which adjacencies are being specified, the second value is the count of adjacent entities, and the remainder of the group is the list of IDs of the adjacent entities.

hid_t mhdf_createAdjacency	(	mhdf_FileHandle	file_handle,
		const char *	elem_handle,
		long	adj_list_size,
		mhdf_Status *	status
	)

Create adjacency data table for nodes, elements, polys, etc.

Create file object for adjacency data for a nodes or a specified element group.

Adjacency data is formated as a sequence of integer groups where the first entry in each group is the ID of the element for which adjacencies are being specified, the second value is the count of adjacent entities, and the remainder of the group is the list of IDs of the adjacent entities.

Parameters:

file_handle	The file.
elem_handle	The element group (or the result of mhdf_node_type_handle for nodes) for which the adjacency data is to be specified.
adj_list_size	The total number of integer values contained in the adjacency data for the specified element group.
status	Passed back status of API call.

Returns:

The HDF5 handle to the connectivity data.

int mhdf_haveAdjacency	(	mhdf_FileHandle	file,
		const char *	elem_handle,
		mhdf_Status *	status
	)

Check if adjacency data is present in the file for the specified element group.

Parameters:

file	The file.
elem_handle	A handle to an element group.
status	Passed back status of API call.

hid_t mhdf_openAdjacency	(	mhdf_FileHandle	file_handle,
		const char *	elem_handle,
		long *	adj_list_size,
		mhdf_Status *	status
	)

Open adjacency data table for nodes, elements, polys, etc.

Open the file object containing adjacency data for a nodes or a specified element group.

Adjacency data is formated as a sequence of integer groups where the first entry in each group is the ID of the element for which adjacencies are being specified, the second value is the count of adjacent entities, and the remainder of the group is the list of IDs of the adjacent entities.

Parameters:

file_handle	The file.
elem_handle	The element group (or the result of mhdf_node_type_handle for nodes) for which the adjacency data is to be specified.
adj_list_size	The total number of integer values contained in the adjacency data for the specified element group.
status	Passed back status of API call.

Returns:

The HDF5 handle to the connectivity data.

void mhdf_readAdjacency	(	hid_t	data_handle,
		long	offset,
		long	count,
		hid_t	hdf_integer_type,
		void *	adj_list_data_out,
		mhdf_Status *	status
	)

Read node/element adjacency data.

Read adjacency data.

Adjacency data is formated as a sequence of integer groups where the first entry in each group is the ID of the element for which adjacencies are being specified, the second value is the count of adjacent entities, and the remainder of the group is the list of IDs of the adjacent entities.

Parameters:

data_handle	Handle returned from mhdf_createAdjacency or mhdf_openAdjacency.
offset	List position at which to start reading. Offset is from the count if integer values written, NOT a count of the number of elements for which adjacency data is written.
count	Number of integer values to reading.
hdf_integer_type	The type of the integer data in adj_list_data_out. Typically H5T_NATIVE_INT or N5T_NATIVE_LONG as defined in H5Tpublic.h. The HDF class of this type object must be H5T_INTEGER
adj_list_data_out	Pointer to memory at which to write adjacency data.
status	Passed back status of API call.

void mhdf_readAdjacencyWithOpt	(	hid_t	data_handle,
		long	offset,
		long	count,
		hid_t	hdf_integer_type,
		void *	adj_list_data_out,
		hid_t	read_prop,
		mhdf_Status *	status
	)

void mhdf_writeAdjacency	(	hid_t	data_handle,
		long	offset,
		long	count,
		hid_t	hdf_integer_type,
		const void *	adj_list_data,
		mhdf_Status *	status
	)

Write node/element adjacency data.

Write adjacency data.

Adjacency data is formated as a sequence of integer groups where the first entry in each group is the ID of the element for which adjacencies are being specified, the second value is the count of adjacent entities, and the remainder of the group is the list of IDs of the adjacent entities.

Parameters:

data_handle	Handle returned from mhdf_createAdjacency or mhdf_openAdjacency.
offset	List position at which to start writing. Offset is from the count if integer values written, NOT a count of the number of elements for which adjacency data is written.
count	Number of integer values to write.
hdf_integer_type	The type of the integer data in adj_list_data. Typically H5T_NATIVE_INT or N5T_NATIVE_LONG as defined in H5Tpublic.h. The HDF class of this type object must be H5T_INTEGER
adj_list_data	Adjacency data to write.
status	Passed back status of API call.

		long	offset,
		long	count,
		hid_t	hdf_integer_type,
		const void *	adj_list_data,
		hid_t	write_prop,
