Examples of com.db4o.ObjectContainer.deactivate()

com.db4o.ObjectContainer.deactivate()

deactivates a stored object by setting all members to NULL.
Primitive types will be set to their default values. Calls to this method save memory. The method has no effect, if the passed object is not stored in the ObjectContainer.

deactivate() triggers Deactivating and Deactivated callbacks.

Be aware that calling this method with a depth parameter greater than 1 sets members on member objects to null. This may have side effects in other places of the application.
