- aggregateInPlaceBy
  
  public <K, V> ImmutableMap<K,V> aggregateInPlaceBy(Function<? super T,? extends K> groupBy, Function0<? extends V> zeroValueFactory, Procedure2<? super V,? super T> mutatingAggregator)
  
  Description copied from interface: RichIterable
  
  Applies an aggregate procedure over the iterable grouping results into a Map based on the specific groupBy function. Aggregate results are required to be mutable as they will be changed in place by the procedure. A second function specifies the initial "zero" aggregate value to work with (i.e. new AtomicInteger(0)).
