I have a question regarding <font face="Courier New, Courier,
monospace">CONTINUE_EXECUTING</font> request key when the filter
has multiple input ports.<br>
<br>
Let <font face="Courier New, Courier, monospace">FilterA</font> and
<font face="Courier New, Courier, monospace">Filter B</font> each
have one output port, and <font face="Courier New, Courier,
monospace">FilterC</font> has two input ports. Assume output port
of <font face="Courier New, Courier, monospace">FilterA</font> and
also <font face="Courier New, Courier, monospace">FilterB </font>are
connected to both input ports 0 and 1 of <font face="Courier New,
Courier, monospace">FilterC</font> respectively. In <font
face="Courier New, Courier, monospace">FilterC::RequestData(...)</font>
something is changed so only one of the input sources of this filter
(say <font face="Courier New, Courier, monospace">FilterA</font>,
bot not<font face="Courier New, Courier, monospace"> FilterB</font>)
should re-execute. So I have <br>
<br>
<font face="Courier New, Courier, monospace">FilterC::RequestData(...){<br>
...<br>
if(change for FilterA needed)<br>
{<br>
request->Set(vtkStreamingDemandDrivenPipeline::CONTINUE_EXECUTING(),1);<br>
return 0;<br>
}<br>
...<br>
}</font><br>
<br>
and the execution should go to <font face="Courier New, Courier,
monospace">FilterC::RequestUpdateExtent(...)</font>. How can I
make the pipeline to only re-execute only <font face="Courier New,
Courier, monospace">FilterA</font>, not <font face="Courier New,
Courier, monospace">FilterB</font> and then return back to <font
face="Courier New, Courier, monospace">FilterC::RequestData(...)</font>?<br>
<br>
Thanks a lot.<br>
