Examples of net.timewalker.ffmq3.utils.RawDataBuffer

net.timewalker.ffmq3.utils.Settings

A RawDataBuffer is a dynamically growing byte array.

It implements {@link java.io.DataOutput} and {@link java.io.DataInput} to write or read data plus additional null-safe versions of the methods.

This class does not implement any synchronization nor bound checking for maximum performance.
Note that the UTF read/write methods are not compatible with the JDK implementation because they were modified to take advantage of the RawDataBuffer layout.

    public static AbstractMessage unserializeFrom( RawDataBuffer rawIn , boolean asInternalCopy )
    {
      int size = rawIn.readInt();
      
      // Extract a sub buffer
      RawDataBuffer rawMessage = new RawDataBuffer(rawIn.readBytes(size));
        byte type = rawMessage.readByte(); 
        AbstractMessage message = MessageType.createInstance(type);
        message.initializeFromRaw(rawMessage); 
        if (asInternalCopy)
            message.setInternalCopy(true);
