Subject svn commit: r627987 - in /commons/proper/math/trunk/src/java/org/apache/commons/math/estimation: AbstractEstimator.java GaussNewtonEstimator.java
Date Fri, 15 Feb 2008 10:01:28 GMT
Author: luc

New Revision: 627987

URL: http://svn.apache.org/viewvc?rev=627987&view=rev
Log:
improved SOC between AbstractEstimator and its derived classes
(changed fields from protected to private, changed methods to final,
added counter incrementation final method)
