Class SubscriberParticipant

  • All Implemented Interfaces:
    EventListener, IAdaptable, IExecutableExtension, IPropertyChangeListener, ISynchronizeParticipant
    public abstract class SubscriberParticipant
extends AbstractSynchronizeParticipant
implements IPropertyChangeListener
    A synchronize participant that displays synchronization information for local resources that are managed via a Subscriber. 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.
    This class is intended to be subclassed.

    Since:
    3.0

    • Constructor Detail

      • SubscriberParticipant

        public SubscriberParticipant()
        Constructor initializes the schedule. Subclasses must call this method.

      • SubscriberParticipant

        public SubscriberParticipant​(ISynchronizeScope scope)
        Constructor which should be called when creating a participant whose resources are to be scoped.
        Parameters:
        scope - a synchronize scope

    • Method Detail

      • getResources

        public IResource[] getResources()
        Returns the resources supervised by this participant. It will either be the roots of the subscriber or the resource scope provided when the subscriber was set.
        Returns:
        the resources supervised by this participant.

                          IWorkbenchSite site)
        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 the shortTaskName and longTaskName can be null in which case, the default values for these are returned by the methods getShortTaskName() and getLongTaskName(IResource[]) will be used.
        Parameters:
        resources - the resources to be refreshed.
        shortTaskName - the taskName of the background job that will run the synchronize or null if the default job name is desired.
        longTaskName - the taskName of the progress monitor running the synchronize or null if the default job name is desired.
        site - the workbench site the synchronize is running from. This can be used to notify the site that a job is running.

        public void dispose()
        Description copied from interface: ISynchronizeParticipant
        Disposes of this synchronize participant and is called to free the resources associated with a participant. When a participant is added to the ISynchronizeManager this method is called when the manager is shutdown or the participant is removed from the manager.

        Within this method a participant may release any resources, fonts, images, etc. held by this part. It is also very important to remove all listeners.

      • validateConfiguration

        protected void validateConfiguration​(ISynchronizePageConfiguration configuration)
        This method is invoked before the given configuration is used to create the page (see createPage(ISynchronizePageConfiguration)). The configuration would have been initialized by initializeConfiguration(ISynchronizePageConfiguration) but may have also been tailored further. This method gives the participant a chance to validate those changes before the page is created.
        Parameters:
        configuration - the page configuration that is about to be used to create a page.

      • setSubscriber

        protected void setSubscriber​(Subscriber subscriber)
        Subclasses must call this method to initialize the participant. Typically this method is called in init(String, IMemento). This method will initialize the sync info collector.
        Parameters:
        subscriber - the subscriber to associate with this participant.

      • setSyncInfoFilter

        protected void setSyncInfoFilter​(SyncInfoFilter filter)
        Provide a filter that is used to filter the contents of the sync info set for the participant. Normally, all out-of-sync resources from the subscriber will be included in the participant's set. However, a filter can be used to exclude some of these out-of-sync resources, if desired.

        Subclasses can invoke this method any time after setSubscriber has been invoked.

        Parameters:
        filter - a sync info filter

      • getAdapter

        public <T> T getAdapter​(Class<T> adapter)
        Description copied from class: PlatformObject
        Returns an object which is an instance of the given class associated with this object. Returns null if no such object can be found.

        This implementation of the method declared by IAdaptable passes the request along to the platform's adapter manager; roughly Platform.getAdapterManager().getAdapter(this, adapter). Subclasses may override this method (however, if they do so, they should invoke the method on their superclass to ensure that the Platform's adapter manager is consulted).

        Specified by:
        getAdapter in interface IAdaptable
        Overrides:
        getAdapter in class PlatformObject
        Type Parameters:
        T - the class type
        Parameters:
        adapter - the class to adapt to
        Returns:
        the adapted object or null
        See Also:
        IAdaptable.getAdapter(Class)
