JS.Class & Uniquity

[Maël Nison]

Hi,

Assuming this :

var C = new JS.Class( 'Foobar', {} );

var a = new C( );

var b = new C( );

Will this statement always be true ?

a.toString( ) != b.toString( )

Thanks,

Yes, if you don't override toString() or hash() -- the default toString() given by JS.Class includes the object's hash, which the default hash() implementation gives a different value for every object. However certain data structures override hash() to match up with the equals() contract -- see http://jsclass.jcoglan.com/equality.html
