Interface ByteStoreAccess

All Known Implementing Classes:
NioByteStoreAccess
public interface ByteStoreAccess
Interface for random access reading for data that has been written into a byte store. This resembles DataInput, but omits some of the methods there, and adds seek(long) and skip(int) methods. A pointer is maintained, and is advanced appropriately by the various read methods.
