Applications have the option to let particular artifacts abort the shutdown sequence and/or perform a task while the shutdown sequence is in process. Artifacts that desire to be part of the shutdown sequence should implement the griffon.core.ShutdownHandler
interface and register themselves with the application instance.The contract of a ShutdownHandler
is very simple
boolean canShutdown(GriffonApplication app)
- return false
to abort the shutdown sequence.
void onShutdown(GriffonApplication app)
- called if the shutdown sequence was not aborted.
There are no default ShutdownHandlers registered with an application.
