This is a forked repository. Have a look at
apache’s commons-lang wiki
for more information.

This fork is for extending commons.lang.Validate with ellipsis notation functions.

An example:

Validate.isTrue(argInt1.intValue > argInt2.intValue, 
                "param2 actually is {1} but must larger than param1 {0} !", argInt1, argInt2);

The benefit of this approach is that all the really time consuming string operations will be postponed and only been done if and only if the validation fails!

I did a few performance tests, and the same function with using ellipsis only needs 5% of the time of the ‘old’ way of doing string concatenations all the time (regardless if the error will be shown or not) in the callers code.
