From 6a37af48d1db199a0f5a9e9c48f7c5f834a90d1b Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Thu, 30 Jul 2020 18:05:02 -0400 Subject: Add "special" Operation classes for new usecases Created place-holder for new "usecases" controller. Note: as of yet, this is still just a normal java project; it will be turned into a full-fledged kie-based controller in a later review. Added some Operation and a few other support classes that will be needed. Note: the detmTarget() method and it's various supporting methods, detmXxx(), found in GetTargetEntityOperation2 were cloned from the pre-existing ControlLoopOperationManager2 class, and modified to fit the strategy of the new controller. Likewise for the junit tests of those methods.
