FUNCTION xpxGetEntityExtentBN (modelId     : GENERIC;
                               entityName   : STRING;
                               VAR extentId : SET OF GENERIC)

The xpxGetEntityExtentBN function returns the aggregateId of the specified entity_extent aggregate. The actual instance type is defined by the modelId and entityName arguments. The aggregateId of the actual entity_extent is returned in the extentId argument. An entity_extent aggregate is a SET that contains all instances of the same type in a model. The number of entity_extents in a model is equal to the number of possible instance types in the model.
