Remarks

Default Modeling framework partition mapping service. This mapper is capable of mapping to two partitions, one for the model, and one for the diagram. The model partition is assumed to be fixed as the partition of the model root associated with the docdata. The diagram partition may vary, and the particular diagram to use is dynamically determined by looking for a target diagram id in the ElementGroupPrototype's target context. The standard DesignSurfaceElementOperations puts the target diagram over which a drag-over or drop operation occurs into the EGP target context. If the target diagram id is not present in the EGP target context, then this partition mapper assumes that the relevant diagram is the first diagram associated with the model. A limitation of this mapper is that it can only map any particular domain class to a single partition, based upon the first embedding defined for the class. Designers requiring a more sophisticated partition mapping service are free to subclass this partition mapper (it provides a couple of override points), or completely replace it, e.g. by overriding ModelingDocData.CreatePartitionMapper, or by providing it as an SElementPartitionMapper through the service provider provided to the Store at creation time.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
