| Object.constructor Property | Flash 5 |
| a reference to the class constructor function used to create the object | read/write |
The constructor property stores a reference to the constructor function that was used to create someObject. For example, the constructor property of a Date object is the Date constructor function:
now = new Date(); now.constructor = = Date; // Yields true
Note that in JavaScript, the constructor property is always read from someObject's constructor's prototype property (someObject._ _proto_ _.constructor). In Flash Player 6 and Flash Player 5, the constructor property is written directly to someObject so that it always faithfully refers to someObject's actual constructor function. For a complete discussion of this subtle deviation, see Section 12.7.3 in Chapter 12.
Overwriting an object's constructor property is not recommended, because it alters the natural structure of class inheritance.
