Model post-processing on file save

[tfonda-fbk]

Hi, in my project I am currently using an IDerivedStateComputer to perform some moderately complex model post-processing. It is my understanding (and my experience seems to confirm this) that the installDerivedState() method of a custom IDerivedStateComputer implementation is invoked very often/continuously while typing. This is a problem for me, because in general while the user types a model, the model itself will be incomplete and it'll evolve/change very rapidly. I'd like to perform my processing only when the model has reached a somewhat stable state, i.e. when the user saves a file. Is there any recommended way of doing this? At the moment I cannot think of any.
Thanks!

without looking at the code at all. maybe you can examine the resourceset to figure out. or mark.
(e.g. there is CompilerPhases which is added by build, but also removed after indexing)
