CeedElemRestriction

int CeedElemRestrictionGetStrides(CeedElemRestriction rstr, CeedInt (*strides)[3])

Get the strides of a strided CeedElemRestriction.

Backend Developer Functions

Parameters

• rstr – [in] CeedElemRestriction

• strides – [out] Variable to store strides array

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionGetOffsets(CeedElemRestriction rstr, CeedMemType mem_type, const CeedInt **offsets)

Get read-only access to a CeedElemRestriction offsets array by memtype.

User Functions

Parameters

• rstr – [in] CeedElemRestriction to retrieve offsets

• mem_type – [in] Memory type on which to access the array. If the backend uses a different memory type, this will perform a copy (possibly cached).

• offsets – [out] Array on memory type mem_type

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionRestoreOffsets(CeedElemRestriction rstr, const CeedInt **offsets)

Restore an offsets array obtained using CeedElemRestrictionGetOffsets()

User Functions

Parameters

• rstr – [in] CeedElemRestriction to restore

• offsets – [in] Array of offset data

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionIsStrided(CeedElemRestriction rstr, bool *is_strided)

Get the strided status of a CeedElemRestriction.

Backend Developer Functions

Parameters

• rstr – [in] CeedElemRestriction

• is_strided – [out] Variable to store strided status, 1 if strided else 0

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionIsOriented(CeedElemRestriction rstr, bool *is_oriented)

Get oriented status of a CeedElemRestriction.

Backend Developer Functions

Parameters

• rstr – [in] CeedElemRestriction

• is_oriented – [out] Variable to store oriented status, 1 if oriented else 0

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionHasBackendStrides(CeedElemRestriction rstr, bool *has_backend_strides)

Get the backend stride status of a CeedElemRestriction.

Backend Developer Functions

Parameters

• rstr – [in] CeedElemRestriction

• has_backend_strides – [out] Variable to store stride status

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionGetELayout(CeedElemRestriction rstr, CeedInt (*layout)[3])

Get the E-vector layout of a CeedElemRestriction.

Backend Developer Functions

Parameters

• rstr – [in] CeedElemRestriction

• layout – [out] Variable to store layout array, stored as [nodes, components, elements]. The data for node i, component j, element k in the E-vector is given by i*layout[0] + j*layout[1] + k*layout[2]

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionSetELayout(CeedElemRestriction rstr, CeedInt layout[3])

Set the E-vector layout of a CeedElemRestriction.

Backend Developer Functions

Parameters

• rstr – [in] CeedElemRestriction

• layout – [in] Variable to containing layout array, stored as [nodes, components, elements]. The data for node i, component j, element k in the E-vector is given by i*layout[0] + j*layout[1] + k*layout[2]

Returns

An error code: 0 - success, otherwise - failure

int CeedElemRestrictionGetData(CeedElemRestriction rstr, void *data)

int CeedElemRestrictionReference(CeedElemRestriction rstr)

Increment the reference counter for a CeedElemRestriction.

Backend Developer Functions

Parameters

• rstr – [inout] ElemRestriction to increment the reference counter

Returns
