All Implemented Interfaces:

java.rmi.Remote, RemoteIter, java.io.Serializable

public class FactoryIter

extends java.rmi.server.UnicastRemoteObject

implements RemoteIter

Iterate over the results from a factory query. Fairly simple. In fact it does not do much but it does mean the factories do not have to be remote objects themselves so it is worth doing. Otherwise we could just have Factory implement remoteIter.

Method Detail

hasNext

public boolean hasNext()
                throws ArchiveException,
                       java.rmi.RemoteException

Should be straight forward but actually not that simple. Dont no if there is a next until we get it !

next

public java.lang.Object next()
                      throws ArchiveException,
                             java.rmi.RemoteException

Return theNext and getthe next object of possible. Next is always running one object ahead so it can respond to hasNext().
