    public class RandomAccessByteProvider
    extends java.lang.Object
    implements ByteProvider
    Deprecated, for removal: This API element is subject to removal in a future version.
    See FileByteProvider as replacement ByteProvider.
    An implementation of ByteProvider where the underlying bytes are supplied by a random access file.

    Note: this implementation is not thread-safe, and using an instance of this class from multiple threads will result in reading incorrect data and/or ArrayIndexOutOfBoundsExceptions.

    See SynchronizedByteProvider as a solution.
