* TensorSyclExtractAccessor.h
*
* \brief:
* ExtractAccessor takes Expression placeHolder expression and the tuple of sycl
* buffers as an input. Using pre-order tree traversal, ExtractAccessor
* recursively calls itself for its children in the expression tree. The
* leaf node in the PlaceHolder expression is nothing but a container preserving
* the order of the actual data in the tuple of sycl buffer. By invoking the
* extract accessor for the PlaceHolder<N>, an accessor is created for the Nth
* buffer in the tuple of buffers. This accessor is then added as an Nth
* element in the tuple of accessors. In this case we preserve the order of data
* in the expression tree.
*
* This is the specialisation of extract accessor method for different operation
* type in the PlaceHolder expression.
*
