How to use

if(console && console.log) alert = console.log;

var Example = new Class({
    Implements: [Clonable],
    text: 'This is the original object',
    log: function()
    {
        alert(this.text);
    },
    cloneInitialize: function() // see Notes
    {
        this.text = 'This is a clone';
    }
});

var object = new Example();
var clone = object.clone();

alert(object == clone); // false

object.log(); // 'This is the original object'
clone.log(); // 'This is a clone'

History

1.0.2 (2010-03-04)

• Better handling of the cloneInitialize method (see notes)

1.0.1 (2010-02-28)

• Bug fix release (self and cross-references handling)

1.0 (2010-02-28)

• First release

Notes

• One argument (boolean) can be passed to the method clone to indicate if all objects referenced in the cloned object should also be cloned (by default, they'll be passed by reference).
• If the class implements a method called cloneInitialize, it will be called on each clones [starting 1.0.2] once all objects have been cloned.
• [starting 1.0.2] The method 'cloneInitialize' gets two arguments : the original object and a boolean indicating if it was a deep clone (see above).
• Handles self-references and cross-references by using the property $clone.
