composing-stream

This kind of stream enables composing of external formats and ligatures using Java-style encapsulations. An open composing-stream is connected either to another composing-stream or to a base stream (either a single-channel-simple-stream or a dual-channel-simple-stream).

A composing-stream has no buffer of its own, but instead relies on state and on the buffering of the base stream it is connected to. Read/write operations on composing-streams are always done with respect to the next lower level stream it is encapsulating.

Like its superclass string-simple-stream, a composing-stream transfers characters instead of octets. However, unlike other string-simple-streams, external-format processing is performed to translate one or more characters into one or more characters, both while reading and while writing.
