Detailed Description

Atlas stream filter.

Filters are used by Codec to transform the byte stream before transmission. The transform must be invertible; that is to say, encoding a string and then decoding it must result in the original string. Filters can be used for compression, encryption or performing checksums and other forms of transmission error detection. A compound filter can be created that acts like a single filter, allowing various filters to be chained together in useful ways such as compressing and then encrypting.
