Annotation Interface EnablePool

@Target(TYPE) @Retention(RUNTIME) @Inherited @Documented @Import(AddPoolConfiguration.class) public @interface EnablePool
The EnablePool annotation configures a Spring Configuration annotated class with a "named" GemFire client Pool bean in the application context. This annotation is used in conjunction with the ClientCacheApplication annotation to add an additional Pool to a GemFire cache client application configured with Spring (Data GemFire). To add more than 1 Pool to your application, this annotation can be nested in the EnablePools annotation.
