Example 3: The <Data Table> Extents

• <Data Tables> may have 1 or more spatial or non-spatial dimensions.

• The dimensional extents of <Data Table> is determined by its <Axis> components.

• A Level 1 API function exists to get a <Data Table’s> extents.

SE_STATUS_CODE_ENUM SE_GetDataTableExtents

{

SE_OBJECT data_table,

SE_DATA_TABLE_EXTENTS *extents_ptr,

SE_UINT32 *cell_count_ptr

);

• The number of cells in the <Data Table> is returned.

• SE_DATA_TABLE_EXTENTS stores the number of <Axis> dimensions and the starting and stopping value for each <Axis>.

• The extents should be freed with the Level 1 function below:

SE_STATUS_CODE_ENUM SE_FreeDataTableExtents

{

SE_DATA_TABLE_EXTENTS *extents_ptr

);
