[Exercise] AST Transformations

AST Transformations

We looking at a lot of AST Transformations in this section. 

Now I want you to go through the documentation and 

find one that we didn't look at and see if you can get it to work on

 your own.

//Person.groovy

package clone

import groovy.transform.AutoClone

@AutoClone

class Person {

    String first

    String last

    List favItems

    Date since

}

//clonedemo.groovy

package clone

def p = new Person(first:'John', last:'Smith', favItems:['ipod', 'shiraz'], since:new Date())

def p2 = p.clone()

assert p instanceof Cloneable

assert p.favItems instanceof Cloneable

assert p.since instanceof Cloneable

assert !(p.first instanceof Cloneable)

assert !p.is(p2)

assert !p.favItems.is(p2.favItems)

assert !p.since.is(p2.since)

assert p.first.is(p2.first)
