Class SubscriberMergeContext

All Implemented Interfaces:
IAdaptable, IMergeContext, ISynchronizationContext

public abstract class SubscriberMergeContext extends MergeContext
A merge context that uses a subscriber to populate the diff tree used by the context. The population of the diff tree is performed by a handler that runs in a background job.

    • SubscriberMergeContext

      protected SubscriberMergeContext(Subscriber subscriber, ISynchronizationScopeManager manager)
      Create a merge context for the given subscriber
      subscriber - the subscriber
      manager - the scope manager
  • Method Details

    • initialize

      protected void initialize()
      Initialize the diff tree of this context. This method must be called before the context is given to clients.
    • getDiffFilter

      protected DiffFilter getDiffFilter()
      Return the diff filter used to filter the differences that the merge context will present to clients.
      the diff filter used to filter the differences that the merge context will present to clients
    • refresh

      public void refresh(ResourceTraversal[] traversals, int flags, IProgressMonitor monitor) throws CoreException
      Description copied from interface: ISynchronizationContext
      Refresh the context in order to update the diff tree returned by ISynchronizationContext.getDiffTree() to include the latest synchronization state for the resources. Any changes will be reported through the change listeners registered with the diff tree of this context.

      Changes to the diff tree may be triggered by a call to this method or by a refresh triggered by some other source. Hence, the callback from the diff tree to report changes may occur in the same thread as the refresh or asynchronously in a separate thread, regardless of who triggered the refresh.

      traversals - the resource traversals which indicate which resources are to be refreshed
      flags - additional refresh behavior. For instance, if RemoteResourceMappingContext.FILE_CONTENTS_REQUIRED is one of the flags, this indicates that the client will be accessing the contents of the files covered by the traversals. NONE should be used when no additional behavior is required
      monitor - a progress monitor, or null if progress reporting is not desired
      CoreException - if the refresh fails. Reasons include:
      • The server could not be contacted for some reason (e.g. the context in which the operation is being called must be short running). The status code will be SERVER_CONTACT_PROHIBITED.

    • dispose

      public void dispose()
      Description copied from interface: ISynchronizationContext
      Dispose of the synchronization context and the cache of the context. This method should be invoked by clients when the context is no longer needed.
      Specified by:
      dispose in interface ISynchronizationContext
      dispose in class SynchronizationContext
    • getSyncInfo

      protected SyncInfo getSyncInfo(IResource resource) throws CoreException
      Return the sync info for the given resource.
      resource - the resource
      the sync info for the resource obtained from the subscriber
      CoreException - if an error occurs
    • getSubscriber

      public Subscriber getSubscriber()
      Return the subscriber associated with this context.
      the subscriber associated with this context
    • runInBackground

      protected void runInBackground(IWorkspaceRunnable runnable)
      Run the given runnable when the background handler for this context is idle. The given runnable should not lock the workspace.
      runnable - the runnable
    • 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
      getAdapter in class MergeContext
      Type Parameters:
      T - the class type
      adapter - the class to adapt to
      the adapted object or null
