This class provides a basic framework for a "bytestream", here defined +//! as a bi-directional, asynchronous pipe of data. It can be used to create +//! several different kinds of bytestream-applications, such as a console or +//! TCP connection, or something more abstract like a security layer or tunnel, +//! all with the same interface. The provided functions make creating such +//! classes simpler. ByteStream is a pure-virtual class, so you do not use it +//! on its own, but instead through a subclass such as \a BSocket. +//! +//! The signals connectionClosed(), delayedCloseFinished(), readyRead(), +//! bytesWritten(), and error() serve the exact same function as those from +//! <A HREF="http://doc.trolltech.com/3.1/qsocket.html">QSocket</A>. +//! +//! The simplest way to create a ByteStream is to reimplement isOpen(), close(), +//! and tryWrite(). Call appendRead() whenever you want to make data available for +//! reading. ByteStream will take care of the buffers with regards to the caller, +//! and will call tryWrite() when the write buffer gains data. It will be your +//! job to call tryWrite() whenever it is acceptable to write more data to +//! the underlying system. +//! +//! If you need more advanced control, reimplement read(), write(), bytesAvailable(), +//! and/or bytesToWrite() as necessary. +//! +//! Use appendRead(), appendWrite(), takeRead(), and takeWrite() to modify the +//! buffers. If you have more advanced requirements, the buffers can be accessed +//! directly with readBuf() and writeBuf(). +//! +//! Also available are the static convenience functions ByteStream::appendArray() +//! and ByteStream::takeArray(), which make dealing with byte queues very easy. + +class ByteStream::Private +{ +public: + Private() {} + + QByteArray readBuf, writeBuf; +}; + +//! +//!
