public abstract class SubscriberParticipant extends AbstractSynchronizeParticipant implements IPropertyChangeListener
A synchronize participant that displays synchronization information for local resources that are managed via aSubscriber
. It maintains a dynamic collection of all out-of-sync resources by listening to workspace resource changes and remote changes thus creating a live view of changes in the workspace.The subscriber can be configured to be synchronized in the background based on a schedule. This effectively refreshes the subscriber and updates the dynamic sync set.
Subclasses will typically want to override the following methods:
- initializeConfiguration: participants can add toolbar actions, configure the context menu, decorator.
- saveState and init: persist settings between sessions.
- Since:
- 3.0

Refresh a participant in the background the result of the refresh are shown in the progress view. Refreshing can also be considered synchronizing, or refreshing the synchronization state. Basically this is a long running operation that will update the participants sync info sets with new changes detected on the server. Either or both of theshortTaskName
andlongTaskName
can benull
in which case, the default values for these are returned by the methodsgetShortTaskName()
andgetLongTaskName(IResource[])
will be used.- Parameters:

setSubscriber
has been invoked.- Parameters:
