VolumePredicates (Apache jclouds 2.0.0 API)

java.lang.Object
- org.jclouds.openstack.cinder.v1.predicates.VolumePredicates

public class VolumePredicates
extends Object

Tests to see if volume 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 Volume status has reached a desired state. This is useful when your Volume needs to be 100% ready before you can continue with execution.

 Volume volume = volumeApi.create(100);

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

 if (!awaitAvailable.apply(volume.getId())) {
    throw new TimeoutException("Timeout on volume: " + volume);
 }

You can also use the static convenience methods as so.

 Volume volume = volumeApi.create(100);

 if (!VolumePredicates.awaitAvailable(volumeApi).apply(volume.getId())) {
    throw new TimeoutException("Timeout on volume: " + volume);
 }
