Package com.ccg.util Description

General Utility Classes.

Whenever libraries of software routines are created, there always seems to be a collection of general purpose utility routines. This package is intended to contain those type of utility classes.

The following example programs have been included to help illustrate usage of some of these classes:

TagLookupEx.java

This program shows how one can chain together several Lookup objects to create a heirarchy when looking up values. It allows one to search for settings first from the command line, then from an optional resource bundle, and finally from the default java system properties.
