BMessageRunnerΒΆ
The BMessageRunner class provides a handy mechanism for automatically sending an arbitrary message to a BMessenger at specified intervals. The application that creates the BMessageRunner can specify the message, the BMessenger to send the message to, how often to send the message, and how many times it should be sent.
The system roster handles actually dispatching the messages to the appropriate BMessengers at the desired time intervals; this class simply acts as an intermediary through which your application asks the roster to schedule sending the messages.
