EventArgs class abstract
An abstract representation of the (optional) arguments provided to handlers when an Event occurs.
This is intended to be extended with your own custom class, if you want to provide subscribers with some data relating to the Event. Alternatively, use one of the three supplied EventArgs derived classes: WhenWhy, Value or Values.
// example
class MyChangedValue extends EventArgs {
int changedValue;
MyChangedValue(this.changedValue);
}
