[Paraview] Questions about writing a reader

[Moreland, Kenneth]

You almost never have to override the ProcessRequest method.  The default ProcessRequest for all the algorithm convenience classes (like vtkImageAlgorithm, vtkPolyDataAlgorithm, and so on) will identify the request and call the appropriate Request* method (RequestInformation, RequestData, etc.) as appropriate.

Subject: [Paraview] Questions about writing a reader

Hello, everyone!
I have a question about writing a reader of my own!
Do I need use the method ProcessRequest to set the output object or just set the type of output object in the method RequestInformation?
And I do NOT know which method in reader is the first to be called when read a file?Is the RequestInformation or something else!
Thank you so much for your help!
