A MetaClassScope specifies the published meta data (MetaClass and MetaProperties) which should be accessible on the mobile device. Further, it is possible to configure the permissions granted on those objects on the mobile.

If an object is published to the client the Web Service tries to load the most accurate MetaClassScope corresponding to the object's MetaClass. If no MetaClass scope for exactely that MetaClass can be located the system looks up the inheritance hierarchy (regarding the data model) if it can find a suitable one.

Own Properties

Name Data type Optional Comment
METACLASS Guid no Reference to the according MetaClass
DELETE_CONFIG Integer no Possibility to configure the delete behavior when a instance of the defined MetaClass gets deleted via the ACM (Web Service)


Classifications

If a MetaClass implements a certain classification the MetaClassScope must publish all required MetaProperties as declared by the classification. Only then the classification is known on the mobile client.

Icons

For deploying MetaClass specific icons it is necessary to create an own MetaClassScope for each MetaClass. Otherwise, the system will always deliver the icon of the most suitable MetaClassScope fitting a parent's MetaClass.

Delete Configuration

The Delete Configuration gives the possibility to configure whether an instance of the configured MetaClass may be deleted via ACM.

Setting Description
NotDeleteable Deletion of an instance of the configured MetaClass via the WebService is not supported
RemoveFromOwner Deletion of an instance is possible via the WebService. The instance will be removed from its owner (the relation/reference will be deleted) but the instance itself will not be deleted from the database.
Deleteable Deletion of an instance of the configured MetaClass via the WebService is not supported and the deleted object will get totally be removed from Ubik (will get deleted in the database).
