Class LoadBalancerPredicates

java.lang.Object
org.jclouds.rackspace.cloudloadbalancers.v1.predicates.LoadBalancerPredicates
public class LoadBalancerPredicates extends Object
Tests to see if loadBalancer has reached status. This class is most useful when paired with a RetryablePredicate as in the code below. This class can be used to block execution until the LoadBalancer status has reached a desired state. This is useful when your LoadBalancer needs to be 100% ready before you can continue with execution. 
 
 LoadBalancer loadBalancer = loadBalancerApi.create(loadBalancerRequest);

 RetryablePredicate<String> awaitAvailable = RetryablePredicate.create(
    LoadBalancerPredicates.available(loadBalancerApi), 600, 10, 10, TimeUnit.SECONDS);

 if (!awaitAvailable.apply(loadBalancer)) {
    throw new TimeoutException("Timeout on loadBalancer: " + loadBalancer);
 }
You can also use the static convenience methods as so. 
 
 LoadBalancer loadBalancer = loadBalancerApi.create(loadBalancerRequest);

 if (!LoadBalancerPredicates.awaitAvailable(loadBalancerApi).apply(loadBalancer)) {
    throw new TimeoutException("Timeout on loadBalancer: " + loadBalancer);
 }

    • awaitAvailable

      public static com.google.common.base.Predicate<LoadBalancer> awaitAvailable(LoadBalancerApi loadBalancerApi)
      Wait until a LoadBalancer is Available.
      Parameters:
      loadBalancerApi - The LoadBalancerApi in the region where your LoadBalancer resides.
      Returns:
      RetryablePredicate That will check the status every 3 seconds for a maxiumum of 5 minutes.

    • awaitDeleted

      public static com.google.common.base.Predicate<LoadBalancer> awaitDeleted(LoadBalancerApi loadBalancerApi)
      Wait until a LoadBalancer no longer exists.
      Parameters:
      loadBalancerApi - The LoadBalancerApi in the region where your LoadBalancer resides.
      Returns:
      RetryablePredicate That will check the whether the LoadBalancer exists every 3 seconds for a maxiumum of 5 minutes.

    • awaitStatus

      public static com.google.common.base.Predicate<LoadBalancer> awaitStatus(LoadBalancerApi loadBalancerApi, LoadBalancer.Status status, long maxWaitInSec, long periodInSec)
