Please don't deprecate Node.getData()

[martinluene]

We use this method to get an iterator for the key-value-pairs of a TreeNode. The proposed alternative solution is to "Use get(Object key) instead.", but this requires to know all keys within this node.

We use this e.g. to remove only out-dated values from the cache. This is much faster than to remove all and recalculate all the values.

What if we provide an api for your to retrieve the keys (under a specific fqn) instead? If we expose Node.getData directly, the caller can bypass our tx/locking/replication interceptor semantics. So it is not a good practice.

I second what Ben says - exposing Node.getData() is certainly not a good idea.

Node.getDataKeys() already exists ...
