From 68c77592f25f9173d2166fa01fb34b4155f4cfcb Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Mon, 20 Nov 2017 20:27:43 +0000 Subject: Remove {Set|Get|Try}Object methods The CJX_Node::{Set|Get|Try}Object methods are used to set CXFA_WidgetData and CXFA_Node objects into the CJX_Node. This is stored in the node as void* data and custom delete methods are passed when needed. Instead, this CL just stores the two types of things we need on the CJX_Node and returns the correct types. This uses a bit more space on the CJX_Node, but it makes the code a lot clearer and simpler.
