From 5c931588582025e983ef457b503a1d3c2e6d41b2 Mon Sep 17 00:00:00 2001 From: Johannes Dahlström Date: Thu, 10 Jul 2014 16:26:01 +0300 Subject: Generate type data for AbstractRendererConnector.createRenderer (#13334) The declared return type of the most-derived getRenderer method is stored to make the default createRenderer implementation work. This is identical to the way AbstractComponentConnector getWidget and createWidget work.
