Description

TMemoryStream is a TStream descendent that stores it's data in memory. It descends directly from TCustomMemoryStream and implements the necessary to allocate and de-allocate memory directly from the heap. It implements the Write method which is missing in TCustomMemoryStream.

TMemoryStream also introduces methods to load the contents of another stream or a file into the memory stream.

It is not necessary to do any memory management manually, as the stream will allocate or de-allocate memory as needed. When the stream is freed, all allocated memory will be freed as well.
