EdmiError edmiClassifyInstance(SdaiInstance id,
                                SdaiInteger *instanceClass)

This operation returns "classification information" about a given entity instance or a given aggregate instance. The "classification information" is:

persistent, scratch or vm (EDMexpressVM) instance.
in case of aggregate: the kind of aggregate
kind of model that locates the instance

The actual model that locates the aggregate instance or entity instance to classify must be open before this operation can be successfully performed.

Arguments

Type	Name	Comment
SdaiInstance	id	A numeric instanceID or aggregateID that uniquely identifies the entity instance or aggregate instance to classify.
SdaiInteger	instanceClass	Address of a variable that receives the result of the operation. The result will be a bitwise OR of the following: META_META_MODEL, DICTIONARY_MODEL, META_MODEL, SYSTEM_MODEL, SESSION_MODEL, DATA_MODEL, ARRAY_AGGREGATE, BAG_AGGREGATE, LIST_AGGREGATE, SET_AGGREGATE, PERSISTENT_INSTANCE, SCRATCH_INSTANCE, VM_INSTANCE, SUBTYPE_AGGREGATE, UNION_AGGREGATE Note: DICTIONARY_MODEL and META_MODEL are two different names of exactly the same, i.e., DICTIONARY_MODEL = META_MODEL

Return Value

Error rendering macro 'excerpt-include' : User 'null' does not have permission to view the page 'US:_r_EDMInterface'.
