public abstract class Assert

extends Object

Assists in validating arguments.

The class is based along the lines of JUnit. If an argument value is deemed invalid, an IllegalArgumentException is thrown. For example:

 Assert.isTrue( i > 0, "The value must be greater than zero: ", i);
 Assert.notNull( surname, "The surname must not be null");
