Subject svn commit: r1353386 - in /commons/proper/math/trunk/src/main/java/org/apache/commons/math3/util: Incrementor.java IterationManager.java
Date Mon, 25 Jun 2012 05:22:59 GMT
Author: celestin
Date: Mon Jun 25 05:22:58 2012
New Revision: 1353386

URL: http://svn.apache.org/viewvc?rev=1353386&view=rev
Log:
Reverted changes committed in r1353140. In o.a.c.m3.util.Incrementor, a NullPointerException
is now thrown if the call-back function specified at construction is null. o.a.c.m3.util.IterationManager
was updated accordingly (used to explicitely use the constructor with null argument).
