TeamEventHandler

public class TeamEventMessenger

Description copied from interface: TeamEventHandler

Callback for handling events related to teams.

NOTE: This is called in the context of the kernel so you must use the provided TeamReservation if you want to do anything in the team that caused the Event. The TeamEvent object is allocated in the kernel Team context.

NOTE: Do not modify the TeamEvent that is passed. You will confuse later receivers of the (same) event object. Do not store the TeamEvent object, as it will be modified for subsequent events.
