IO stream composition and serialization with Ada Utility Library

By Stephane Carrez

IO stream composition is a powerful mechanism that has been provided by Java platform since its early days. It allows one or more transformations to be performed when reading or writing some content. Doing such transformation is transparent to the reader or the writer. For example, in the reading process, it allows to first decode the content in Base64, then decrypt the binary stream and then decompress that decrypted binary stream, all this in a transparent manner. The writing process would first compress what is written, then encrypt and encode in Base64. All these transformations are activated by connecting one stream object to another. In Ada, such IO stream composition is possible with Ada Utility Library.
