Interface RandomDataInput

All Known Subinterfaces:

Bytes<Underlying>, BytesStore<B,Underlying>

All Known Implementing Classes:

AbstractBytes, ExpectedBytesStore, HeapBytesStore, MappedBytes, MappedBytesStore, NativeBytes, NativeBytesStore, NoBytesStore, PointerBytesStore, UncheckedBytes, VanillaBytes

public interface RandomDataInput

This allows random access to the underling bytes. This instance can be used across threads as it is stateless. The thread safety of the underlying data depends on how the methods are used.
