From 8aa365e5d7d7f14ac4e0002be30968df77b08b56 Mon Sep 17 00:00:00 2001
From: Magesh Umasankar <umagesh@apache.org>
Date: Sat, 16 Feb 2002 02:29:34 +0000
Subject: [PATCH] 1.  Change Parameterizable interface's setParameters method
 signature such that it takes in an array of type Parameter instead of
 Hashtable. 2.  Introduce "type" as an attribute to nested param.
