Abstract
The cache control unit 15 of the mobile terminal 10 receives an access request for an instance of an object that specifies data to which applications 13 refers, and in the case that an instance of the object does not exist, creates an instance of the object and a counter. In addition, an instance of a reference setting class is created, the reference that refers to the instance of the requested object is set and the result is returned to the application 13, and the counter is incremented by 1. In the case that a release notification for the instance of the reference setting class is received, the counter is decremented by 1, and when the counter has reached 0, the instance of the object is released.
