Overview ¶
Package aggregator is a utility package to create basic aggregators. Min/Max/Average aggregators are type specific, so an integerAvg() aggregator expects all elements to be integers. There is no conversion executed while accumulating on the server side, so if there is any other type met an exception will be thrown on the server side.
The attributePath given in the factory method allows the aggregator to operate on the value extracted by navigating to the given attributePath on each object that has been returned from a query. The attribute path may be simple, e.g. "name", or nested "address.city". The given attribute path should not be empty, otherwise an error will be returned from client side.
Server version should be at least 3.8.
