042: * OMG definition: The WfResourceIterator interface specializes the WfBase::BaseIterator
043: * interface and adds specific process operations. The following attributes can be used in
044: * query expressions: key, name, priority, description, state.
045: * <p>
046: * We extended OMG's interface by duplicating methods, and adding additional parameter
047: * that represents transaction. If you use methods without SharkTransaction parameter, the
048: * transaction will be implicitly created, and if you use it with SharkTransaction
049: * parameter you must obey to some rules explained in HowTo documentation.
050: * <p>
051: * Also, look at our implementation API documentation of this interface to see which
052: * additional attributes can be used in query expressions.
