Interface RandomAccess

All Superinterfaces:

ArrayDataInput, AutoCloseable, Closeable, DataInput, FitsIO

All Known Implementing Classes:

BufferedFile

public interface RandomAccess
extends ArrayDataInput

These packages define the methods which indicate that an i/o stream may be accessed in arbitrary order. The method signatures are taken from RandomAccessFile though that class does not implement this interface.
