[Insight-developers] testing modified times of process objects

[Josh Cates]

Hello folks,

How can I test a filter to see if it has been modified since its Execute()
method was last called?  

For example say I want to do something like:

 MyFilterClass::Execute()
 {
   if ( this->HasBeenModifiedSinceLastExecuteCall() )
   {
     this->RecalculateSomeFilterParameters();
   }

   Filter();
 }


Josh.
