Assumes the boxes are both in the same index space, and that box R is completely contained in both the source and destination boxes. Modifies the domain of this BaseFab by shifting. There is no effect upon the array memory. Directions are zero-based. There is no effect upon the array memory.
Directions are zero-based.
There is no effect upon the array memory. Modifies the domain of this BaseFab by shifting by half indices. There is no effect upon the array memory. The size does not include the size of R and comps. Assumes that sufficient memory for the buffer has already been allocated by the caller.
