Package org.jclouds.compute.predicates.internal

Class RefreshNodeAndDoubleCheckOnFailUnlessStatusInvalid

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>>, 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.
