bool IsUsedSince ( const int32 Epoch
) const

 Have we run collision detection since this Epoch (inclusive) Chaos/Collision/ParticlePairMidPhase.h  

void SetCollision ( const FPBDCollisionConstraint& Constraint,
const FCollisionContext& Context
)

 Set the collision from the parameter and activate it This is used by the Resim restore functionality. Chaos/Collision/ParticlePairMidPhase.h  

void WakeCollision ( const int32 SleepEpoch,
const int32 CurrentEpoch
)

 Reactivate the constraint @parame SleepEpoch The tick on which the particle went to sleep. Only constraints that were active when the particle went to sleep should be reactivated. Chaos/Collision/ParticlePairMidPhase.h
