  • Field Details

    • P_VISIBLE_MODEL_PROVIDER

      public static final String P_VISIBLE_MODEL_PROVIDER

      See Also:

    • ALL_MODEL_PROVIDERS_VISIBLE

      public static final String ALL_MODEL_PROVIDERS_VISIBLE
      Constant used with the P_ACTIVE_MODEL_PROVIDER property to indicate that all enabled model providers are active.
      See Also:

    • PROP_ENABLED_MODEL_PROVIDERS

      public static final String PROP_ENABLED_MODEL_PROVIDERS
      Property constant used during property change notification to indicate that the enabled model providers for this participant have changed.
      See Also:

    • PROP_ACTIVE_SAVEABLE

      public static final String PROP_ACTIVE_SAVEABLE

      Description copied from class: AbstractSynchronizeParticipant
      This method is invoked after a page configuration is created but before it is returned by the createPageConfiguration method. Subclasses can implement this method to tailor the configuration in ways appropriate to the participant.
      Specified by:
      initializeConfiguration in class AbstractSynchronizeParticipant
      Parameters:
      configuration - the newly create page configuration

    • createMergeActionGroup

      public final IPageBookViewPage createPage(ISynchronizePageConfiguration configuration)
      Description copied from interface: ISynchronizeParticipant

      Parameters:
      configuration - used to initialize the page
      Returns:
      a page book view page representation of this synchronize participant

    • run

      public void run(IWorkbenchPart part)
      Description copied from interface: ISynchronizeParticipant
      Runs the participants action. Typically this would be some action to refresh the synchronization state of the participant. This action is run from the global synchronize drop-down.
      Parameters:
      part - the part in which the action is run or null if the action is not being run in a workbench part.

    • refresh

      public final void refresh(IWorkbenchSite site, ResourceMapping[] mappings)
      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 participant's context with new changes detected on the server.
      Parameters:
      site - the workbench site the synchronize is running from. This can be used to notify the site that a job is running.
      mappings - the resource mappings to be refreshed

    • dispose

      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.

      Clients should not call this method (the synchronize manager calls this method at appropriate times).

    • initializeContext

      protected void initializeContext(SynchronizationContext context)

      Returns:
      a compare input for the model object or null

    • hasCompareInputFor

      public boolean hasCompareInputFor(Object object)
      Return whether their is a compare input associated with the given object. In other words, return true if asCompareInput(Object) would return a value and false if it would return null.

      whether their is a compare input associated with the given object

    • isMergingEnabled

    • setMergingEnabled

      public void setMergingEnabled(boolean mergingEnabled)

    • getShortTaskName

      protected String getShortTaskName()
      Returns the short task name (e.g. no more than 25 characters) to describe the behavior of the refresh operation to the user. This is typically shown in the status line when this participant is refreshed in the background. When refreshed in the foreground, only the long task name is shown.
      Returns:
      the short task name to show in the status line.

    • getLongTaskName

      protected String getLongTaskName(ResourceMapping[] mappings)

    • 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
