Detailed Description

FConstraintsInteractionCache is designed to minimize the number of requests made to the ConstraintManager and thus improve performance. it is particularly useful for interface components that need to be updated frequently. note that PerHandleConstraints and PerTargetConstraints are reset when the constraint graph is updated, to keep it synchronized.
