All Implemented Interfaces:

RemoteAdapterFactory

public class RemoteAdapterFactoryImpl
extends java.lang.Object
implements RemoteAdapterFactory

Default implementation of the RemoteAdapterFactory interface. This factory uses the server adapters defined in this package as the default adapter implementations. Subclasses can override or extend the default adapters by implementing the corresponding factory methods.

The bufferSize property can be used to configure the size of the buffer used by iterators to speed up iterator traversal over the network.

optimizeIterator

protected RemoteIterator optimizeIterator(RemoteIterator remote)
                                   throws java.rmi.RemoteException

Optimizes the given remote iterator for transmission across the network. This method retrieves the first set of elements from the iterator by calling RemoteIterator.nextObjects() and then asks for the total size of the iterator. If the size is unkown or greater than the length of the retrieved array, then the elements, the size, and the remote iterator reference are wrapped into a BufferIterator instance that gets passed over the network. If the retrieved array of elements contains all the elements in the iterator, then the iterator instance is discarded and just the elements are wrapped into a ArrayIterator instance to be passed to the client.

Subclasses can override this method to provide alternative optimizations.

Parameters:

remote - remote iterator

Returns:

optimized remote iterator

Throws:

java.rmi.RemoteException - on RMI errors
