| * The Exceptions QuickStart Example. |
| * |
| * This example takes the following steps: |
| * |
| * 1. Create CacheFactory using the user specified settings or from the gfcpp.properties file by default. |
| * 2. Create a Geode Cache. |
| * 3. Get the example generic Regions from the Cache. |
| * 4. Perform some operations which should cause exceptions. |
| * 5. Close the Cache. |
| * 6. Put an Entry into the Region when Cache is already closed. |
