When a developer subscribes to a public event, he processes the public event in the onReceiveEvent() callback function and writes the following code.

EventRunner runner = EventRunner.create();

MyEventHandler myHandler = new

MyEventHandler(rurner);

@Override public void onReceiveEvent(CommonEventData commonEventData){

final AsyncCommonEventResult result=goAsyncCommonEvent Runnable task = new

Runnable(){

@override pub1ic void run {

......

The action to be performed, defined by the developer result.finishCommonEvent();

}

};

myHandler.postTask(task);

}

Gives subscribers permissions
implements asynchronous operations, which solves the problem that time-consuming operations cannot be performed on onReceiveEvent
sets the priority of ordered public events
The publisher has the permission to publish sticky public events
