  • Constructor Details

    • TextFallbackMergeViewer

      public TextFallbackMergeViewer(org.eclipse.swt.widgets.Composite parent, EMFCompareConfiguration configuration)
      Creates an instance under the given parent using the given configuration.
      Parameters:
      parent - the parent composite under which to create this viewer.
      configuration - the EMF compare configuration used by this viewer.

  • Method Details

    • handleEditingDomainChange

      public void handleEditingDomainChange(ICompareEditingDomainChange event)
      Listens to editing domain changes on the event bus.
      Parameters:
      event - the editing domain change event.

    • addPropertyChangeListener

      public void addPropertyChangeListener(org.eclipse.jface.util.IPropertyChangeListener listener)

      This implementation subverts calls to super so that nothing can actually listen to underlying state changes to the dirty state of this viewer's source viewers. It manages its own listeners and informs listeners of the dirty state based on changes to command stack state.

      Specified by:
      addPropertyChangeListener in interface org.eclipse.compare.IPropertyChangeNotifier
      Overrides:
      addPropertyChangeListener in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.removePropertyChangeListener(IPropertyChangeListener)

    • removePropertyChangeListener

      public void removePropertyChangeListener(org.eclipse.jface.util.IPropertyChangeListener listener)

      This implementation subverts calls to super so that nothing can actually listen to underlying state changes to the dirty state of this viewer's source viewers. It manages its own listeners.

      Specified by:
      removePropertyChangeListener in interface org.eclipse.compare.IPropertyChangeNotifier
      Overrides:
      removePropertyChangeListener in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.removePropertyChangeListener(IPropertyChangeListener)

    • isLeftDirty

      protected boolean isLeftDirty()

      This implementation returns the state of the command stack when the command stack is updating the dirty state.

      Overrides:
      isLeftDirty in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.isLeftDirty()

    • setLeftDirty

      protected void setLeftDirty(boolean dirty)

      This implementation updates the header because the label includes a dirty state indication.

      Overrides:
      setLeftDirty in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.setLeftDirty(boolean)

    • isRightDirty

      protected boolean isRightDirty()

      This implementation returns the state of the command stack when the command stack is updating the dirty state.

      Overrides:
      isRightDirty in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.isRightDirty()

    • setRightDirty

      protected void setRightDirty(boolean dirty)

      This implementation updates the header because the label includes a dirty state indication.

      Overrides:
      setRightDirty in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.setRightDirty(boolean)

    • createToolItems

      protected void createToolItems(org.eclipse.jface.action.ToolBarManager tbm)

      This implementation also creates a preview action that's useful for showing the saved contents of resource in their current state of modification.

      Overrides:
      createToolItems in class org.eclipse.compare.contentmergeviewer.TextMergeViewer
      See Also:
      • TextMergeViewer.createToolItems(ToolBarManager)

    • updateToolItems

      protected void updateToolItems()

      This implementation also updates the preview action.

      Overrides:
      updateToolItems in class org.eclipse.compare.contentmergeviewer.TextMergeViewer
      See Also:
      • TextMergeViewer.updateToolItems()

    • getCompareConfiguration

      protected EMFCompareConfiguration getCompareConfiguration()

      This implementation assumes the configuration must be an EMFCompareConfiguration, returning it as such.

      Overrides:
      getCompareConfiguration in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.getCompareConfiguration()

    • setContentProvider

      public void setContentProvider(org.eclipse.jface.viewers.IContentProvider contentProvider)

      This specialized implementation ignores content provider changes except when explicitly set in the constructor and when this implementation is handling mirror changes.

      Overrides:
      setContentProvider in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.setContentProvider(IContentProvider)

    • setInput

      public void setInput(Object input)

      This implementation is specialized to adapt the input and to select the objects of the input.

      Overrides:
      setInput in class org.eclipse.jface.viewers.ContentViewer
      See Also:
      • ContentViewer.setInput(Object)

    • createSourceViewer

      protected org.eclipse.jface.text.source.SourceViewer createSourceViewer(org.eclipse.swt.widgets.Composite parent, int textOrientation)

      This implementation simply delegates to super but it is used to record the ancesorViewer, leftViewer, and rightViewer which are needed in setInput(Object) to select objects.

      Overrides:
      createSourceViewer in class org.eclipse.compare.contentmergeviewer.TextMergeViewer
      See Also:
      • TextMergeViewer.createSourceViewer(Composite, int)

    • getInput

      public Object getInput()

      This class' specialized setInput method transforms the real input, so it's important that we return the originalInput when that isn't null.

      Specified by:
      getInput in interface org.eclipse.jface.viewers.IInputProvider
      Overrides:
      getInput in class org.eclipse.jface.viewers.ContentViewer
      See Also:

    • handleDispose

      protected void handleDispose(org.eclipse.swt.events.DisposeEvent event)
      Overrides:
      handleDispose in class org.eclipse.compare.contentmergeviewer.TextMergeViewer
      See Also:
      • TextMergeViewer.handleDispose(org.eclipse.swt.events.DisposeEvent)

    • handlePropertyChangeEvent

      protected void handlePropertyChangeEvent(org.eclipse.jface.util.PropertyChangeEvent event)

      This implementation uses the mirror manager to subvert super's handling of mirror state changes so that it can handle the state change in a better way than does the base class.

      Overrides:
      handlePropertyChangeEvent in class org.eclipse.compare.contentmergeviewer.TextMergeViewer
      See Also:
      • TextMergeViewer.handlePropertyChangeEvent(PropertyChangeEvent)

    • getTitle

      public String getTitle()
      Overrides:
      getTitle in class org.eclipse.compare.contentmergeviewer.ContentMergeViewer
      See Also:
      • ContentMergeViewer.getTitle()

      public Object getOriginalInput()

    • getEffectiveInput

      public Object getEffectiveInput()
