Looks like the javadoc is incomplete.

This looks different from what is in Increment in 0.94:

> Increment is the only operation in the class of mutators that does not extend 
> Mutation. It mostly duplicates what Mutation provides, but not quite. The 
> signatures for setWriteToWAL and getFamilyMap are slightly different. This 
> can be inconvenient because it requires special case code and therefore could 
> be considered an API design nit. Unfortunately it is not a simple change: The 
> interface is marked stable and the internals of the family map are different 
> from other mutation types. The latter is why I suspect this was not addressed 
> when Mutation was introduced.
