[ITK-users] Composite Filter with variable stdvector of filters inside

[Jose Ignacio Prieto]

Hi all,
I am trying to create a composite filter for a 4D dataset that will use
different cascaded 2D filters on the inside. For this, I have created a
double std vector that holds all the 2D filters. I have also set some param
setters for this filters (that perform a double for inside, setting the
param to each filter and then calling modified() on the outside one). I
have another method called UpdateNumberofFilters, that depending on 2 ints
(num of Z slices, num of T timeframes) will push back more filters to the
2D array of filters.
My problem is that I dont know which function should call the
UpdateNumofFilters. It should be done before the setters but after the
constructor and after setting those two ints. I want to design it so that
if I change a param after calling update I dont have to run the whole
filter again, so I dont want it to be under the GenerateData() method.

Thank you very much for your insights.
