Class Validate

java.lang.Object

com.twelvemonkeys.lang.Validate

public final class Validate
extends Object

Kind of like org.apache.commons.lang.Validate. Just smarter. ;-)

Uses type parameterized return values, thus making it possible to check constructor arguments before they are passed on to super or this type constructors.
