NullArgumentException (Commons Math 2.2 API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.lang.RuntimeException
    - - java.lang.IllegalArgumentException
      - org.apache.commons.math.exception.MathIllegalArgumentException
        
        org.apache.commons.math.exception.NullArgumentException

All Implemented Interfaces:

java.io.Serializable, MathThrowable
```
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. Proagation of NullPointerException from within Commons-Math is construed to be a bug.

2.2
