org.eclipse.ui.plugin.AbstractUIPlugin
AbstractUIPlugin
implementation of this Plugin
method refreshes the plug-in actions. Subclasses may extend this method,
but must send super first.
Starts up this plug-in.
This method should be overridden in subclasses that need to do something when this plug-in is started. Implementors should call the inherited method at the first possible point to ensure that any system requirements can be met.
If this method throws an exception, it is taken as an indication that plug-in initialization has failed; as a result, the plug-in will not be activated; moreover, the plug-in will be marked as disabled and ineligible for activation for the duration.
Note 1: This method is automatically invoked by the platform the first time any code in the plug-in is executed.
Note 2: This method is intended to perform simple initialization of the plug-in environment. The platform may terminate initializers that do not complete in a timely fashion.
Note 3: The class loader typically has monitors acquired during invocation of this method. It is strongly recommended that this method avoid synchronized blocks or other thread locking mechanisms, as this would lead to deadlock vulnerability.
Note 4: The supplied bundle context represents the plug-in to the OSGi framework. For security reasons, it is strongly recommended that this object should not be divulged.
Note 5: This method and the Plugin.stop(BundleContext)
may be called from separate threads,
but the OSGi framework ensures that both methods will not be called simultaneously.

AbstractUIPlugin
implementation of this Plugin
method saves this plug-in's preference and dialog stores and shuts down
its image registry (if they are in use). Subclasses may extend this
method, but must send super last. A try-finally statement should
be used where necessary to ensure that super.stop()
is
always done.
Stops this plug-in.
This method should be re-implemented in subclasses that need to do something when the plug-in is shut down. Implementors should call the inherited method as late as possible to ensure that any system requirements can be met.
Plug-in shutdown code should be robust. In particular, this method should always make an effort to shut down the plug-in. Furthermore, the code should not assume that the plug-in was started successfully.
Note 1: If a plug-in has been automatically started, this method will be automatically invoked by the platform when the platform is shut down.
Note 2: This method is intended to perform simple termination of the plug-in environment. The platform may terminate invocations that do not complete in a timely fashion.
Note 3: The supplied bundle context represents the plug-in to the OSGi framework. For security reasons, it is strongly recommended that this object should not be divulged.
Note 4: This method and the Plugin.start(BundleContext)
