Usage

From source file:org.jclouds.examples.rackspace.cloudblockstorage.DetachVolume.java

/**
 * @return Server The Server created in the CreateVolumeAndAttach example
 *///from   w w w . jav  a2s  .  c  om
private VolumeAttachment getVolumeAttachment() {
    FluentIterable<? extends Server> servers = serverApi.listInDetail().concat();

    for (Server server : servers) {
        if (server.getName().startsWith(NAME)) {
            FluentIterable<? extends VolumeAttachment> attachments = volumeAttachmentApi
                    .listAttachmentsOnServer(server.getId());

            return attachments.iterator().next();
        }
    }

    throw new RuntimeException(NAME + " not found. Run the CreateVolumeAndAttach example first.");
