Config -- A Java class for dealing with configuration options.

Overview

Config is a Java class that allows you to deal with configuration options from a variety of sources such as a properties file, command line or programmatically assigned.

Building

Most of the code is in the Config.java file. A sample application is provided in TestConfig.java. To build the sample application, just run:

javac *.java

Running

The sample application supports a number of options whose values are read from a Java properties file (config.prop). You can dump these values with:

java TestConfig

To change any of these configuration options from the command line, try something like:

java TestConfig -host foo.com -port 1111 -debug true

You should see the modified values in the resulting dump. Option values can be checked and validated in various ways. For example, if you used a nonsense value like xyz for the debug option above, you'll see an exception.
