Thank you Andrew. The unwrap() method works just fine. But I was wondering if JClouds has provision for something on the following guidelines:
The nodes/instances that we receive from the generic jclouds call populates the following fields private final Status status; private final String backendStatus; private final int loginPort; private final Set<String> publicAddresses; private final Set<String> privateAddresses; @Nullable private final LoginCredentials credentials; @Nullable private final String group; @Nullable private final String imageId; @Nullable private final Hardware hardware; @Nullable private final OperatingSystem os; @Nullable private final String hostname; Is there any provision in JClouds where the rest of the provider-specific attributes for a particular instance/node are stored in key value pair form? Going by the unwrap() way would require us to be provider-aware and hence losing out on having a generic code. On the other hand, having key-value pair would just require skimming through the map, irrespective of any provider. If only it exists :) On Wed, Aug 7, 2013 at 7:13 PM, Andrew Phillips <andr...@apache.org> wrote: > Here the nodes will be represented using NodeMetaData having standard >> attributes which hold true for all the cloud providers.
