Authorization of joining of transformation chain instances

摘要

The authorizing of transformation chain instances of different transformation chain classes to join so as to act as a compound transformation chain instance. Class-level authorized dependencies are identified between transformation chain classes. Then, instance-level authorization is performed in accordance with one or more joining criteria, presuming that the instances are of appropriate classes that may be joined. The joining allows the instances to act as a single compound transformation chain whereby data is permitted to flow across the boundaries of the constituent transformation chain instances. New transformation chain instances may be joined to the compound transformation chain instances, and transformation chain instances may be removed from the compound transformation chain instance, thereby dynamically changing the compound application.
