endUpdates

public static void endUpdates()

waitFinished

public static void waitFinished()

Allows tests to wait while processing of events is finished.

add

public static void add(ManifestSection.LoaderSection s)
                throws Exception

Adds new loader when previous and following are specified. An attempt will be made to (re-)order the loader pool according to specified dependencies.

If a loader of the same class already existed in the pool, that will be removed and replaced with the new one.

Parameters:

s - adds loader section

Throws:

Exception

store

public static void store()
                  throws IOException

Throws:

IOException

load

public static void load()
                 throws IOException

Throws:

IOException

remove

public static boolean remove(DataLoader dl,
                             NbLoaderPool pool)

Removes the loader. It is only removed from the list but if an DataObject instance created exists it will be still valid.

So the only difference is that when a DataObject is searched for a FileObject this loader will not be taken into account.

The loader pool may be resorted.

Parameters:

dl - data loader to remove

Returns:

true if the loader was registered and false if not

getNbLoaderPool

public static NbLoaderPool getNbLoaderPool()

Returns the only instance of the loader pool in our system. There's no other way to get an instance of this class, loader pool is singleton too.

Returns:

loader pool instance

taskFinished

public void taskFinished(Task task)

Specified by:

taskFinished in interface TaskListener

loaders

protected Enumeration<DataLoader> loaders()

Enumerates all loaders. Loaders are taken from children structure of NbLoaderPool.

Specified by:

loaders in class DataLoaderPool

propertyChange

public void propertyChange(PropertyChangeEvent ev)

Listener to property changes.

Specified by:

propertyChange in interface PropertyChangeListener

run

public void run()

Called from the request task

Specified by:

run in interface Runnable

resultChanged

public void resultChanged(LookupEvent ev)

Specified by:

resultChanged in interface LookupListener
