isObjectFrozen
isObjectFrozen(object: Object): Boolean;
The isObjectFrozen method of the Object class returns true if the volatility state of the object specified in the object parameter is frozen (that is, cannot be updated).
A frozen object can be updated only by first changing its volatility to Volatility_Stable or Volatility_Volatile.
The Schema Inspector displays class and object volatility by default, which enables you to check whether objects and collections are set to stable or frozen without having to write code to determine the volatility state of an object or collection.
