NullArgumentException (VirtualDataSet API)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.lang.RuntimeException
    - - java.lang.NullPointerException
      - org.apache.commons.math4.exception.NullArgumentException

All Implemented Interfaces:

java.io.Serializable, ExceptionContextProvider
```
public class NullArgumentException
extends java.lang.NullPointerException
implements ExceptionContextProvider
```
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.
Note: from 4.0 onwards, this class extends NullPointerException instead of MathIllegalArgumentException.

Since:

2.2
