public class IsNull
extends UnaryExpression
implements org.jvnet.jaxb2_commons.lang.Equals2, org.jvnet.jaxb2_commons.lang.HashCode2, org.jvnet.jaxb2_commons.lang.ToString2

The IsNull operator determines whether or not its argument evaluates to null. If the argument evaluates to null, the result is true; otherwise, the result is false.
