From aeb4a51ef82c71c9a65d11f77aeedb53bea0e983 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Sat, 25 May 2013 11:08:08 +0200 Subject: object_array: add function object_array_filter() Add a function that allows unwanted entries in an object_array to be removed. This encapsulation is a step towards giving object_array ownership of its entries' name memory.
