=== 2.2.3.2 Object Deletion Mechanism === Java Card technology, version 2.2.2 offers an optional, object deletion mechanism. Applications designed to run on these implementations can use the facility by invoking the appropriate API. See **//Application Programming Interface, Java Card Platform, Version 2.2.2//**. But, the facility is best suited for updating large objects such as certificates and keys atomically. Therefore, application programmers should conserve on the allocation of objects.
