Record Management System
Overview
The most common mechanism for persistently storing data on a MIDP device is through
RMS. RMS provides the capability to store variable length records on the device. Those
records are accessible to any MIDlet in the MIDlet Suite, but not to MIDlets outside of the
MIDlet Suite. The RMS implementation of the Motorola C370, C450, and C550 series of
handsets is MIDP compliant, so there are no significant additions or changes to the MIDP
specification.
Class Description
