ExtendedEventArgs class abstract

An abstract representation of the (optional) arguments provided to handlers when an ExtendedEvent occurs.

This is intended to be extended with your own custom class, if you want to provide subscribers with some data relating to the ExtendedEvent. Alternatively, use one of the supplied EventArgs derived classes: StdEventArgs, GenericEventArgs1 or GenericEventArgs2.

// example
class ValueEventArgs extends EventArgs {
  int changedValue;
  ValueEventArgs(this.changedValue);
}
