/*
 * The BasicOperations QuickStart Example.
 *
 * This example takes the following steps:
 *
 * 1. Create a Geode Cache.
 * 2. Create the example Region Programmatically.
 * 3.a. Put Entries (Key and Value pairs) into the Region.
 * 3.b. If in 64 bit mode put over 4 GB data to demonstrate capacity.
 * 4. Get Entries from the Region.
 * 5. Invalidate an Entry in the Region.
 * 6. Destroy an Entry in the Region.
 * 7. Close the Cache.
