+/// @class DataBufferHeap DataBufferHeap.h "lldb/Core/DataBufferHeap.h"
+/// @brief A subclass of DataBuffer that stores a data buffer on the heap.
+///
+/// This class keeps its data in a heap based buffer that is owned by
+/// the object. This class is best used to store chunks of data that
+/// are created or read from sources that can't intelligently and lazily
+/// fault new data pages in. Large amounts of data that comes from files
+/// should probably use the DataBufferMemoryMap class.
