All Implemented Interfaces:

java.io.Serializable, ExceptionContextProvider

public class NullArgumentException
extends MathIllegalArgumentException

All conditions checks that fail due to a null argument must throw this exception. This class is meant to signal a precondition violation ("null is an illegal argument") and so does not extend the standard NullPointerException. Propagation of NullPointerException from within Commons-Math is construed to be a bug.
