code: public static <KeyIn, ValueIn, ValueOut> Supplier<KeyIn, ValueIn, ValueOut> all(
              PropertyExtractor<ValueIn, ValueOut> propertyExtractor) {
  
          return new AcceptAllSupplier(propertyExtractor);
      }
docs: The predefined Supplier selects all values and performs the given
  {@link com.hazelcast.mapreduce.aggregation.PropertyExtractor}s transformation to the
  input data. The returned value type of the transformation needs to match the expected
  value type of the aggregation.
  
  @param <KeyIn>    the input key type
  @param <ValueIn>  the input value type
  @param <ValueOut> the supplied value type
  @return all values from the underlying data structure transformed using the given PropertyExtractor
