svn commit: r1585800 - in /pivot:
branches/2.0.x/core/src/org/apache/pivot/util/ListenerList.java
trunk/core/src/org/apache/pivot/util/ListenerList.java
Author: rwhitcomb
Date: Tue Apr 8 18:08:49 2014
New Revision: 1585800
URL: http://svn.apache.org/r1585800
Log:
PIVOT-941: Allow random access to a ListenerList via a "get(int)" method. This is
easier in some situations than iterating through the list to find a particular
element.
