<b>This class is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
|
||
|
|
<p> The TQDataSink class is an asynchronous consumer of data.
|
||
|
|
<p> A data sink is an object which receives data from some source in an
|
||
|
|
asynchronous manner. This means that at some time not determined by
|
||
|
|
the data sink, blocks of data are given to it from processing. The
|
||
|
|
data sink is able to limit the maximum size of such blocks which it
|
||
|
|
is currently able to process.

<h3 class=fn>void <a name="eof"></a>TQDataSink::eof ()<tt> [pure virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> This function will be called when no more data is available for
|
||
|
|
processing.
|
||
|
|
|
||
|
|
<h3 class=fn>void <a name="maybeReady"></a>TQDataSink::maybeReady ()
|
||
|
|
</h3>
|
||
|
|
This should be called whenever <a href="#readyToReceive">readyToReceive</a>() might have become non-zero.
|
||
|
13 years ago
|
It is merely calls <a href="ntqasyncio.html#ready">TQAsyncIO::ready</a>() if readyToReceive() is non-zero.

<h3 class=fn>int <a name="readyToReceive"></a>TQDataSink::readyToReceive ()<tt> [pure virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> The data sink should return a value indicating how much data it is ready
|
||
|
|
to consume. This may be 0.
|
||
|
|
|
||
|
|
<h3 class=fn>void <a name="receive"></a>TQDataSink::receive ( const uchar *, int count )<tt> [pure virtual]</tt>
|
||
|
|
</h3>
|
||
|
|
|
||
|
|
<p> This function is called to provide data for the data sink. The <em>count</em>
|
||
|
|
will be no more than the amount indicated by the most recent call to
|
||
|
|
<a href="#readyToReceive">readyToReceive</a>(). The sink must use all the provided data.
