Interface ReversibleLoadStoreFunc

All Superinterfaces:
LoadFunc, StoreFunc
All Known Implementing Classes:
BinStorage, PigStorage, RandomSampleLoader

public interface ReversibleLoadStoreFunc
extends LoadFunc, StoreFunc

This interface is used to implement classes that can perform both Load and Store functionalities in a symmetric fashion (thus reversible). The symmetry property of implementations is used in the optimization engine therefore violation of this property while implementing this interface is likely to result in unexpected output from executions.
