RefreshNodeAndDoubleCheckOnFailUnlessStatusInvalid (Apache jclouds 1.9.3 API)

java.lang.Object
- org.jclouds.compute.predicates.internal.RefreshAndDoubleCheckOnFailUnlessStatusInvalid<NodeMetadata.Status,NodeMetadata>
- - org.jclouds.compute.predicates.internal.RefreshNodeAndDoubleCheckOnFailUnlessStatusInvalid

All Implemented Interfaces:

com.google.common.base.Predicate<AtomicReference<NodeMetadata>>

Direct Known Subclasses:

AtomicNodeRunning, AtomicNodeSuspended
```
@Singleton
public class RefreshNodeAndDoubleCheckOnFailUnlessStatusInvalid
extends RefreshAndDoubleCheckOnFailUnlessStatusInvalid<NodeMetadata.Status,NodeMetadata>
```
The point of RefreshAndDoubleCheckOnFailUnlessStateInvalid is to keep an atomic reference to a node, so as to eliminate a redundant ComputeService#getNodeMetadata call after the predicate passes.
