One form of batching optimization is to combine multiple messages into one message. For the examples we’ve examined so far, this is easily illustrated. Simply add a method to access all attributes of the server object in one access:^[83]

class ServerObjectDataCopy
{
  public boolean bool;
  public int number;
  public String string;
}

public class ServerObjectImpl
{
  public ServerObjectDataCopy getAll( );
  ...

Using this method to batch the three access methods into one access makes the combined (uncached) access of all the attributes three times faster.
