Name	Remarks	Include Path
virtual TUniquePtr< FNetworkPhysicsDataHelper > Clone()		Physics/NetworkPhysicsComponent.h
virtual bool CopyAlteredData ( const Chaos::FBaseRewindHistory* From, FNetworkPhysicsDataCollection& To )	Copy data from the rewind history to the networked data collection and only copy data that has been altered since it was created (i.e. the client created an input that the server later altered)	Physics/NetworkPhysicsComponent.h
virtual void CopyData ( const FNetworkPhysicsDataCollection& From, Chaos::FBaseRewindHistory* To )	Copy data from the networked data collection to the rewind history	Physics/NetworkPhysicsComponent.h
virtual void CopyData ( const Chaos::FBaseRewindHistory* From, FNetworkPhysicsDataCollection& To )	Copy data from the rewind history to the networked data collection	Physics/NetworkPhysicsComponent.h
virtual void CopyDataGrowingOrdered ( const FNetworkPhysicsDataCollection& From, Chaos::FBaseRewindHistory* To )	Copy data from the networked data collection to the rewind history and store the data ordered instead of circular and grow the history to fit all unique data	Physics/NetworkPhysicsComponent.h
virtual void CopyIncrementalData ( const Chaos::FBaseRewindHistory* From, FNetworkPhysicsDataCollection& To )	Copy data from the rewind history to the networked data collection and only copy data that is newer than the already existing data in the data collection	Physics/NetworkPhysicsComponent.h
virtual TUniquePtr< FNetworkPhysicsPayload > CreateUniqueData()		Physics/NetworkPhysicsComponent.h
virtual TUniquePtr< Chaos::FBaseRewindHistory > CreateUniqueRewindHistory ( const int32 Size ) const		Physics/NetworkPhysicsComponent.h
virtual bool IsUsingLegacyData()		Physics/NetworkPhysicsComponent.h
virtual void ValidateData ( Chaos::FBaseRewindHistory* History, INetworkPhysicsInputState_External& Interface )	Call the ValidateData callback on the external implementation interface for data in the provided rewind history	Physics/NetworkPhysicsComponent.h
virtual void ValidateData ( Chaos::FBaseRewindHistory* History, INetworkPhysicsInputState_Internal& Interface )	Call the ValidateData callback on the internal implementation interface for data in the provided rewind history	Physics/NetworkPhysicsComponent.h
