Interface ERXGuardedObjectInterface

All Known Implementing Classes:

ERXCustomObject, ERXGenericRecord

public interface ERXGuardedObjectInterface

The guarded object interface is used as a way to ensure that objects that are not supposed to be deleted or updated don't accidently get deleted or updated. Look at ERXGenericRecord for an implementation. This interface is also used within ERD2W applications to determine if the edit icon or the trash can icon should be displayed.
