From 757222979bc02d0aaba1870eea36413383d15bde Mon Sep 17 00:00:00 2001 From: Maros Marsalek Date: Tue, 8 Nov 2016 10:13:36 +0100 Subject: HONEYCOMB-270 Add isPresent() to Readers/Customizers So that they can influence whether empty data is to be considered as present + Move registries implementations from util to impl + Introduce DelegatingReader trait + Extend GenericReader where possible to reduce duplication Change-Id: I5a416acd0c4eab1fbc30fcbe585719991dbe9215 Signed-off-by: Maros Marsalek --- .../fd/honeycomb/benchmark/util/StaticReader.java | 5 +
