# Dispatch Data

An object that manages a memory-based data buffer and exposes it as a contiguous block of memory.

## Overview

Overview The memory buffer managed by this object may be a single contiguous block of memory, or it may consist of multiple discontiguous blocks. For the discontiguous case, the dispatch data object makes it appear as if the memory is contiguous.
