public class IsNullCondition

extends Condition

This class provides the implementation for creating a 'IS null' condition statement.

The following example demonstrates how to use this class:

 IsNullCondition nullCond = new IsNullCondition("urn:schemas:contacts:givenName");
 System.out.println(nullCond);
 

Calling toSQL() or toString() will return the SQL representation of this object. For example, the above example would yield:

 "urn:schemas:contacts:givenName" IS null
