/*
 * The RefIDExample QuickStart Example.
 * This example creates two pools through XML and sets region attributes using
 * refid.
 * This example takes the following steps:
 *
 * 1. Create a Geode Cache.
 * 2. Now it creates 2 Pools with the names poolName1, poolName2 respectively.
 * 3. Sets the region attribute using refid.
 * 4. Gets the region "root1" with poolName1, and region "root2" with poolName2.
 * 5. Check for the region attribute set through refid.
 * 6. Put Entries (Key and Value pairs) into both the Regions.
 * 7. Get Entries from the Regions.
 * 8. Invalidate an Entry in both the Regions.
 * 9. Destroy an Entry in both the Regions.
 * 10. Close the Cache.
