I thought it was twice. The first one ParaView when creates the
reader to call CanReadFile in its search for potential readers of
the file. The second one when it builds the pipeline.<br>

<p class="MsoNormal">Hello ParaView,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve inherited a project that writes
plugins for ParaView 3.14.1, serial. While debugging I found
out that the constructor for one of this project’s file
readers is called 3 times when loading a file. I thought this
was odd, so I tried setting a break point on
vtkUnstructuredGridReader’s ctor and discovered that it’s
called twice. However, a constructor for vtk source plugin
that I wrote is only called once, as I would have guessed for
the others.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is it normal for readers to have their
constructors called multiple times when loading a file?
