| | Set up the midphase based on the ShapesArrays of the two particles Only intended to be called once right after constructor. We don't do this work in the constructor so that we can reduce the time that the lock is held when allocating new MidPhases.

| | Whether the particle pair is sleeping and therefore contacts should not be culled (they will be reused on wake)
|
| |
| CHAOS_API void | SetIsSleeping (const bool bInIsSleeping, const int32 CurrentEpoch) |
| | Update the sleeping state If this switches the state to Awake, it will reactivate any collisions between the particle pair that were active when they went to sleep.

| CHAOS_API void | DetachParticle (FGeometryParticleHandle *Particle) |
| | Destroy all collisions and prevent this midphasae from being used any more. Called when one of its particles is destoyed. It will be culled at the next Prune in the CollisionConstraintAllocator. We don't delete it immediately so that we don't have to remove it from either Particle's ParticleCollisions array (which is O(N) and unnecessary when the particles are being destroyed)

| |
| CHAOS_API void | Reset () |

| CHAOS_API void | InjectCollision (const FPBDCollisionConstraint &Constraint, const FCollisionContext &Context) |
| | Copy a collision and activate it This is used by the Resim system to restore saved colisions. If there is already a matching constraint it will be overwritten, otherwise a new constraint will be added.

| ECollisionVisitorResult | VisitCollisions (const TLambda &Visitor, const ECollisionVisitorFlags VisitFlags=ECollisionVisitorFlags::VisitDefault) |

A midphase for a particle pair where one or both have a large number of collisions shapes, or a non-flat hierarchy of shapes. This is the general-purpose collision path and does not cache as much data as the FShapePairParticlePairMidPhase and must visit the geometry hierarchy on both shapes every time we detect collisions. It must also rerun the collision filters on overlapping pairs, among other things. It does, howver, take advantage of the BVH held in the root ImplicitObjectUnion if there is one, so it can be much faster the the FShapePairParticlePairMidPhase when the set of potentially colliding pairs is very large.
