From 66ebac4959f0ee48340159354bbb21578573ef5b Mon Sep 17 00:00:00 2001
From: abobrov <abobrov@localhost>
Date: Mon, 20 Aug 2007 13:46:51 +0000
Subject: [PATCH] - remove toVerboseString method from the public EntryCache API. - make toVerboseString method private in implementation classes. - make toVerboseString use StringBuilder instead of string concat. - make toVerboseString use ServerConstants.EOL where required.
