::This is essentially a JavaScript version of [https://developer.mozilla.org/En/SpiderMonkey/JSAPI_Reference/JSPropertyOp JSClass.addProperty], and is called immediately after a new property has been added to ''wrappee''. ''name'' is the name of the property being accessed, and ''defaultValue'' is the value that JavaScript would ordinarily set the initial value of the property to. This function should return the initial value to set the property to, which may be ''defaultValue'' or something different. Alternatively, the method may also throw an exception. | |||

''name'' is the name of the property being deleted. This function should return <code>true</code> if the property can be deleted, and <code>false</code> if not. | |||
