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()

  void write(FlumeEventQueue queue) throws IOException {
    LOG.info("Writing checkoint to " + file + ", size = " + queue.size());
    RandomAccessFile dataOutput = new RandomAccessFile(file, "rw");
    try {
      // write out a small number
      dataOutput.writeLong(Long.MIN_VALUE);
      // write a the queue itself
      dataOutput.writeInt(queue.getCapacity());
      queue.write(dataOutput);
      // force all changes to disk
      dataOutput.getChannel().force(true);
