public final Class ConstraintUtilities

extends Object
Class Inheritance
Simple utility methods for enforcing various types of data constraints.

Some of the functionality here is reproduced in Spring (and in other 3rd party JARs), but we need this to work at the client-side too and may opt not to such 3rd party products there. Regardless, this is trivial anyway! (This is copied from ph-commons-util.)
