Object.zHashCode
zHashCode() -> string
Description
Return the unique hash code assigned to this object.
This can be used to determine if two objects are identical.
This logic can be overridden by defining an onHashCode hook method for the object.
$o = { a: 123 }
$o.hashCode() //= 'd4ef024362f6db5554cce08d77f9fc5f'
