LifecycleManager

protected LifecycleManager()

Subclass constructor.

Method Detail

getDefault

public static LifecycleManager getDefault()

Get the default lifecycle manager. Normally this is found in Lookup.getDefault() but if no instance is found there, a fallback instance is returned which behaves as follows:

1. LifecycleManager.saveAll() does nothing
2. LifecycleManager.exit() calls System.exit(int) with an exit code of 0

This is useful for unit tests and perhaps standalone library usage.

Returns:

the default instance (never null)

saveAll

public abstract void saveAll()

Save all opened objects.

exit

public abstract void exit()

Exit NetBeans. This method will return only if System.exit(int) fails, or if at least one component of the system refuses to exit (because it cannot be properly shut down).

exit

public void exit(int status)

Exit NetBeans with the given exit code. This method will return only if System.exit(int) fails, or if at least one component of the system refuses to exit (because it cannot be properly shut down). The default implementation calls LifecycleManager.exit() for compatibility reasons, but subclasses are encouraged to provide better implementation.

Parameters:

status - the exit code of the application

8.23

markForRestart

public void markForRestart()
                    throws UnsupportedOperationException

Request that the application restart immediately after next being shut down. You may want to then call LifecycleManager.exit() to go ahead and restart now.

Throws:

UnsupportedOperationException - if this request cannot be honored
