Examples of java.io.DataInputStream.readShort()

java.io.DataInputStream.readShort()
See the general contract of the readShort method of DataInput.
Bytes for this operation are read from the contained input stream. @return the next two bytes of this input stream, interpreted as asigned 16-bit number. @exception EOFException if this input stream reaches the end beforereading two 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

            DataInputStream in=new DataInputStream(new ByteArrayInputStream(buf));
            byte type=in.readByte();
            if(type == NULL)
                return null;
            if(type == METHOD_CALL) {
                short id=in.readShort();
                short length=in.readShort();
                Object[] args=length > 0? new Object[length] : null;
                if(args != null) {
                    for(int i=0; i < args.length; i++)
                        args[i]=Util.objectFromStream(in);
