onAdd method

  1. @override
void onAdd (
  1. T event
)
override

An extension point for sub-classes. Perform any side-effect / state management you need to here, rather than overriding the add method directly.

Implementation

@override
void onAdd(T event) {
  if (_queue.length == _maxSize) {
    _queue.removeFirst();
  }

  _queue.add(event);
}
