Examples of java.io.DataInputStream.readFully()

java.io.DataInputStream.readFully()
See the general contract of the readFully method of DataInput.
Bytes for this operation are read from the contained input stream. @param b the buffer into which the data is read. @exception EOFException if this input stream reaches the end beforereading all the bytes. @exception IOException the stream has been closed and the containedinput stream does not support reading after close, or another I/O error occurs. @see java.io.FilterInputStream#in
