Examples of java.io.RandomAccessFile.writeLong()

java.io.RandomAccessFile.writeLong()
Writes a 64-bit long to this output stream. The resulting output is the 8 bytes, highest order first, of val. @param val the long to be written. @throws IOException If an error occurs attempting to write to this DataOutputStream. @see DataInput#readLong()

            RandomAccessFile raf = getRandomAccessFile();


            // the first number in the file is the count
            m_countPosition = 0L;
            raf.seek(m_countPosition);
            raf.writeLong(m_count);


            // the second number in the file is the head pointer
            m_headPosition = raf.getFilePointer();
            raf.seek(m_headPosition);
            raf.writeLong(m_head);
