| OMG definition: The WfProcessIterator interface specializes the WfBase::BaseIterator
interface and adds specific process operations. The following attributes can be used in
query expressions: key, name, priority, description, state.
We extended OMG's interface by duplicating methods, and adding additional parameter
that represents transaction. If you use methods without SharkTransaction parameter, the
transaction will be implicitly created, and if you use it with SharkTransaction
parameter you must obey to some rules explained in HowTo documentation.
Also, look at our implementation API documentation of this interface to see which
additional attributes can be used in query expressions.
