Description
TWindowedStream is a
TStream descendent that can be used to provide a window
on the data of another stream. The position and size of the window can be
determined in the constructor, and the stream will behave as a normal stream.
The actual reading (or writing) will happen on the source stream.
If the source stream has some limitations (e.g. no Seek) then the
TWindowedStream will inherit these limitations.
The TWindowedStream will keep track of the last position it used,
and will attempt to restore it if it was modified between calls to
Read and Write.
