Package containings the elements of the BPDM M1 library User (M1) library capturing commonly needed aspects of behavioral happenings as instances of the class in the Happening and Change model. The library defines: Events to represent various behavior lifecycle events, such as starting and ending of individual Courses. A Courses called the Behavior Occurrence. It is a generalization of all M1 dynamic models (see the Composition Model). Event Parts of the Behavior Occurrence for the various behavioral changes, such as startPart and finishPart. These are typed by the various M1 changes, such as Start and End Behavioral Changes Successions between the Event Parts above for universal constraints, such as the End being after the Start. Abort Event is a Event that manifests that the the course of a Course is being interrupted. The source of the Abort Event can be internal or external to the Course. Error Event is a Event that manifests that an error has occurred that will lead to the End Event of the Course. The source of the Error Event is always internal to the Course. Normal End Event is a Event that manifests the normal End Event of a Course Course that produces common behavior lifecycle changes, such as as Start or End Event. Racing Behavior ensures that all the Behavior Steps connected by Race Connection start at the same time, and that the first one to finish aborts the others (see the Happening and Change Model). Race Behavior contains: - One Behavior Step, called the Racing Contestant which is bound to all the steps connected by the M1 race connection. This ensures that all the contestants are treated the same way. - Two Immediate Processing Successions connecting the Contestant to itself. One succession refers to the start part of the Contestant on both ends (see the Happening and Change Model), specifying that all the contestant behavioral happenings start at the same time. The other succession has the finish part on one end and the abort part on the other, specifying that any contestant happening that finishes will be accompanied by a simultaneous abort of the others. This succession has the Irreflexive condition applied (see the Composition Model), to prevent the finishing contestant from aborting itself. Behavior Step of the Racing Behavior is bound to all the steps connected by the M1 race connection to ensures that all the contestants are treated the same way.
