Class ElementGen<T>

java.lang.Object
  org.jcheck.generator.ElementGen<T>

All Implemented Interfaces:

Gen<T>

public class ElementGen<T>
extends java.lang.Object
implements Gen<T>

Generate a random object from the list of objects in the constructor. This generator should be subclassed. The following example will create a generator that will generate only 2, 4 and 6.

 public class TwoFourSixGen extends ElementGen<Integer>
 {
     public TwoFourSixGen()
     {
         super(2,4,6);
     }
 }

Method Detail

arbitrary

public T arbitrary(java.util.Random random,
                   long size)

Description copied from interface: Gen

Returns an arbitrary object of type T. The object should not have a size greater than size (or smaller than -size). What the size actually referrs to depends on the implementation, but it could be the number of nodes in a tree, pixels in an image etc.

The supplied random generator should be the only source of randomness used in the generator.

Specified by:

arbitrary in interface Gen<T>

Parameters:

random - the random generator that should be used when randomness is needed.

size - the limiting factor

Returns:

a random object
