/**
 * Allows programmatic querying of {@link Deployment}s.
 * 
 * Note that it is impossible to retrieve the deployment resources through the
 * results of this operation, since that would cause a huge transfer of
 * (possibly) unneeded bytes over the wire.
 * 
 * To retrieve the actual bytes of a deployment resource use the operations on
 * the {@link RepositoryService#getDeploymentResourceNames(String)} and
 * {@link RepositoryService#getResourceAsStream(String, String)}
