Class CompressedRamStorage<T>

java.lang.Object

org.nd4j.storage.CompressedRamStorage<T>

All Implemented Interfaces:

AbstractStorage<T>

public class CompressedRamStorage<T>
extends Object
implements AbstractStorage<T>

AbstractStorage implementation, with Integer as key. Primary goal is storage of individual rows/slices in system ram, even if working in GPU environment This implementation IS thread-safe, so it can be easily used together with ParallelWrapper
