Struct ArrayDataOperationUtilities<DIM, TYPE, OP> provides generic looping operations for all array-based patch data types. The operations are templated on spatial dimension, data type, and the operation that will be performed on individual array elements in the innermost loop.

Perform operation on a subset of data components of source and destination array data objects and put results in destination array data object.
- Parameters
-
| dst | Reference to destination array data object. |
| src | Const reference to source array data object. |
| opbox | Const reference to Box indicating index space region of operation. |
| src_shift | Const reference to IntVector indicating shift required to put source index space region into destination index space region. |
| dst_start_depth | Integer specifying starting depth component of operation in destination array. |
| src_start_depth | Integer specifying starting depth component of operation in source array. |
| num_depth | Integer number of depth components on which to perform operation. |
| op | Const reference to object that performs operations on individual data array elements. |
When assertion checking is active, assertion will result when any of the depth-related arguments are out-of-bounds for the given array data objects.
◆ doArrayDataBufferOperationOnBox()
template<int DIM, class TYPE , class OP >
Perform operation on all data components of array data object and corresponding buffer data, putting results in either the array data object or buffer.
- Parameters
-
| arraydata | Const reference to array data object. |
| buffer | Const pointer to first element in buffer. |
| opbox | Const reference to Box indicating operation region in index space of array data object. |
| src_is_buffer | Boolean value indicating whether buffer is source data for operation; if true results will be placed in array data object, otherwise results will go in buffer. |
| op | Const reference to object that performs operations on individual data array elements. |
When assertion checking is active, assertion will result when buffer pointer is null or operation box is not the same as the array data box.
