DX.Stream

Delphi TStream utilities: memory-to-file fallback stream and TBytes class helper

VariableStream

Store variable length data into any TStream, using a fast index

stream-adapter

A Pascal stream class that is implemented as an interface, thus offering reference-counting.

lib.BinaryStreaming

Library designed to ease streaming of binary data into memory or TStream descendants.

lib.SimpleCompress

Very simple library providing functions for (de)compression of streams (descendants of TStream class), files and memory buffers. Actual (de)compression is done by ZLib library.

[WIP] Layered stream provides a descendant of TStream class that is intended for situations, where there is a need for some (possibly multi-layered) processing of streamed data, and parallel processing is not desirable or possible.

Lib.BinaryStreaming

Library designed to ease streaming of binary data into memory or TStream descendants.

Lib.SimpleCompress

Very simple library providing functions for (de)compression of streams (descendants of TStream class), files and memory buffers. Actual (de)compression is done by ZLib library.

ATBinHex

Viewer control for TStream of unlimited size. Has several view modes: text with fixed/variable length, hex dump, Unicode.
