DiscardInstance

This event is triggered after an "instance" (see below) has been discarded.

Parameters

Parameter	Description
instid	intValue, ID of the discarded instance.
classid	intValue, class ID of the discarded instance.
name	strValue, name of the discarded instance.
modelid (idValue, optional) -ue, model ID of the discarded instance.
realinstanceid	intValue, "Real" ID of the instance (core internal ID).
realclassid	intValue, "Real" ID of the class (core internal ID).

Exit value:

Remarks

Instances are modeling objects, record rows, attribute profiles.

Note that, as the instance does not exist any more, you cannot use instid for core access here.

Mind the difference between deleting and discarding. Discarding means removing from memory, but the discarded instance may still exist as a part of its model (in the database). Deleting means, that the instance is removed from its model. Deleting implies discarding.

	SETG id_InstId: (instid) 
	SETG id_ClassId: (classid) 
	SETG id_ModelId: (modelid)
	SETG str_InstanceName: (name)
	SETG id_RealInstId: (realinstanceid)
	SETg id_RealClassId: (realclassid)
	
	CC "AdoScript" INFOBOX ("Modelid:   " + STR(id_ModelId)  + "  ClassId:  " + STR(id_ClassId) + 
	"  InstanceId:   " + STR(id_InstId) + "  InstanceName:   " + (str_InstanceName)
	+ "  RealClassId:  " + STR(id_RealClassId) + "  RealInstId:  " + STR(id_RealInstId))
