Example

String md5Hash = stringMD5("my password");

Date Parse

Another way to generate a unique ID.

This class uses reflection to locate option setters. Client class must contains methods setFile (to receive file names from the command line) and setOption### (to receive option ###).

Implementation-independent XML builder.

A handy class I use all the time to encapsulate the idea of whether two events coincide. For example, given a time period representing a shift, and a list of time periods representing transactions or sessions or whatever, find which ones are either totally or partially within the time period. This class make it a bit easier.

if you use the same buildfiles on your local codebase and your continuous integration buildserver, the if-attribute for ant's targets comes in handy...
