GeodeEmbeddedPolicy.RefCountPolicy (Calcite 1.18.0 Test API)

java.lang.Object
- org.junit.rules.ExternalResource
- - org.apache.calcite.adapter.geode.rel.GeodeEmbeddedPolicy
  - - org.apache.calcite.adapter.geode.rel.GeodeEmbeddedPolicy.RefCountPolicy

All Implemented Interfaces:

org.junit.rules.TestRule

Enclosing class:

GeodeEmbeddedPolicy
```
private static class GeodeEmbeddedPolicy.RefCountPolicy
extends GeodeEmbeddedPolicy
```
Calls before() and after() methods only once (for first and last subscriber respectively). The implementation counts number of times before() was called which determines number of "clients". Delegate after() is called when that count reaches zero again (when last "client" called that method).

    Description copied from class: GeodeEmbeddedPolicy
    
    Allows this instance to be shared by multiple test classes (in parallel). Guarantees that before() and after() methods will be called only once. This setup is useful for maven (surefire) plugin which executes tests in parallel (including @ClassRule methods) and may initialize (or destroy) same resource multiple times.
