Hi! Recently I have to write a lot of code involving *ClusterGroup* manipulations. And found my self that I missed *isEmpty()* method on *ClusterGroup* class. Instead I forced to write *prj.nodes().isEmpty().*
Also I think that *isEmpty()* method could be implemented in more efficient (no need to iterate over all nodes) and optimized manner, without creating underlying collection for nodes. Thoughts? -- Alexey Kuznetsov GridGain Systems www.gridgain.com
