I wrote my own reader plugin, which can reader data from a file successfully
However, I also add some options on the UI to control how to convert raw data into vtk data, but these control option have nothing with raw data, if these options changed, we only need to change the “convert process”, not necessarily read data again.
But after I change these option on UI and click “Apply” button again, the process will call “RequestData”, which have to read data again.
My question what is the best practice in my situation?
How can I avoid unnecessary data reading?
Thanks and Best Regards,
