How to get number of RR groups

[d.healey]

Is there a way to get the number of groups in the current sample map? I know we have getRRGroupsForMessage(); but I don't know if that can be used for this purpose, any ideas?

Sampler1.getAttribute(Sampler1.RRGroupAmount) should always return the current number of RR groups.

Oh duh of course! Thank you.
