addListener

void addListener(PipeletTrackerListener listener)

add a listener that will be notified about new or deactivated pipelet classes on bundle changes. This is also set as a service reference bind method in component descriptor, so the suggested way to use this is to register PipeletListener service instead of calling the method directly.

Parameters:

listener - a new listener for PipeletTracker events.

removeListener

void removeListener(PipeletTrackerListener listener)

remove a listener that will be notified about new or deactivated pipelet classes on bundle changes. This is also set as a service reference unbind method in component descriptor, so the suggested way to use this is to register PipeletListener service instead of calling the method directly.

Parameters:

listener - an obsolete listener for PipeletTracker events.
