* The modes of operation the data set can be used in.
*
* FILE: The device data is held on disk and loaded into memory when needed.
* Caching is used to clear out stale items. Lowest memory use and slowest
* device detection.
*
* MEMORY: The device data is loaded into memory. Offers the fastest device
* detection in Java managed code, but a slower startup time.
*
* MEMORY_MAPPED: The device data is loaded into memory as a byte array.
* Java class instances are created when needed and then cleared from the cache.
*
* Objects of this class should not be created directly as they are part of the
* internal logic.

* For more information see:
