edmiGetScratchInstances

SdaiAggr edmiGetScratchInstances(void);

Returns the instances aggregate of the model contents instance in the scratch model. The scratch model can contain instances of any available type (any entity definition) in an EDMdatabase. All scratch instances in an EDMdatabase are located in the scratch model. The instances aggregates contains all scratch instances in an EDMserver session. The scratch model belongs to an EDMserver session, hence the scratch model (and all scratch instances are not persistent in an EDMdatabase. The scratch model will be deleted when the open EDMserver session is closed and a new empty scratch model will be created when a new EDMserver session is opened. All EDMinterface read access operations that are applicable on SET aggregates are applicable to the returned aggregate.
