<hr/>
<p>A protocol that receives lines and/or raw data, depending on mode.</p>
<p>In line mode, each line that's received becomes a callback to <a
href="twisted.protocols.basic.LineReceiver.html#lineReceived"
class="link"><code>lineReceived</code></a>. In raw data mode, each chunk
of raw data becomes a callback to <a
href="twisted.protocols.basic.LineReceiver.html#rawDataReceived"
class="link"><code>rawDataReceived</code></a>. The <a
href="twisted.protocols.basic.LineReceiver.html#setLineMode"
class="link"><code>setLineMode</code></a> and <a
href="twisted.protocols.basic.LineReceiver.html#setRawMode"
class="link"><code>setRawMode</code></a> methods switch between the two
modes.</p>
This is useful for line-oriented protocols such as IRC, HTTP, POP,
etc.
