Interface MetaDataListener

public interface MetaDataListener

MetaDataListeners are registered in the MetaDataManager using the MetaDataManager.addMetaDataListener(MetaDataListener, String[]) method. They are called when a metatype, for which they registered to receive events, has been added, removed or modified.

When a listener is no more to receive metatype events it may be unregistered through the MetaDataManager.removeMetaDataListener(MetaDataListener) method.

static int	SOURCE_XML Source type which specifies that the corresponding metatype is provided by a XML resource.

Method Summary

void	metaDataChanged(int event, long bundleId, java.lang.String type, java.lang.String pid, java.lang.String version, int sourceType) When meta data changes the MetaDataManager service should notify the interested MetaDataListener instances by calling this method.
