virtual |
BlackBoard interface created notification.
This is called whenever an interface is created for a type that you registered for.
type | type of the interface. If you want to store this make a copy as it is not guaranteed that the supplied string exists for longer than the duration of the method call |
id | ID of the newly created interface. If you want to store this make a copy as it is not guaranteed that the supplied string exists for longer than the duration of the method call |

virtual |
BlackBoard data changed notification.
This is called whenever the data in an interface that you registered for is modified. This happens if a writer calls the Interface::write() method.
interface | interface instance that you supplied to bbil_add_data_interface() |

A reading instance has been closed for a watched interface.
This is called whenever a reading instance of an interface you are watching is closed.
interface | interface instance that you supplied to bbil_add_reader_interface() |
instance_serial | the instance serial of the reading instance that has just been removed. |
