.all_by_measure ⇒ Object

Finds all measures and groups the sub measures

Returns:

  • Array - This returns an Array of Hashes. Each Hash will represent a top level measure with an ID, name, and category. It will also have an array called subs containing hashes with an ID and name for each sub-measure.
