That forces me to get/create the node first, and then perform the operation. It doesn't look very atomic. Would batches help here? Regarding generics, there are more types that could be parameterized (e.g. it is possible to make the coupling between DeltaAware and its Delta implementation more type-safe). The implementation classes of generic interfaces usually use raw types. And this TreeCache.getCache() thing :) I'm not a big fan of AtomicMapCache.getAtomicMap() either... BTW: How do I actually get a reference to AtomicMapCache? I haven't seen any API except for casting... -KS
