Class TriggerSuccessFuture<T>
java.lang.Object
com.googlecode.objectify.cache.TriggerFuture<T>
com.googlecode.objectify.cache.TriggerSuccessFuture<T>
- All Implemented Interfaces:
- java.util.concurrent.Future<T>
public abstract class TriggerSuccessFuture<T>
- extends TriggerFuture<T>
Extends TriggerFuture so that it only gets triggered on successful (no exception)
completion of the Future. This prevents, for example, cache put()s
from firing when concurrency exceptions are thrown.
