Prototype COOSYSTEM@1.1:AttrGetPrototype

The prototype for actions that read a property value. These actions are specified in the property attractget of a property definition. These actions are called by the kernel, when a property value is actually read. For volatile properties these actions are called for each access, otherwise the kernel caches the result of that action until the object is changed or ObjectRefresh is called on the object. Such an action can be used to change the value of the property before it leaves the kernel.
