public class StructureDiffViewer extends DiffTreeViewer
IStructureCreator
to retrieve a hierarchical structure from the input object (an ICompareInput)
and perform a two-way or three-way compare on it.
This class may be instantiated; it is not intended to be subclassed outside this package.

|---|
StructureDiffViewer(Composite parent,
CompareConfiguration configuration)
Creates a new viewer under the given SWT parent with the specified configuration.
|
StructureDiffViewer(Tree tree,
CompareConfiguration configuration)
Creates a new viewer for the given SWT tree control with the specified configuration.
|
| Modifier and Type | Method and Description |
|---|---|
protected void |
compareInputChanged(ICompareInput input)
Recreates the comparable structures for the input sides.
|
protected void |
contentChanged(IContentChangeNotifier changed)
Calls
diff whenever the byte contents changes. |
protected void |
copySelected(boolean leftToRight)
Overridden to call the
save method on the structure creator after
nodes have been copied from one side to the other side of an input object. |
protected void |
diff()
Runs the difference engine and refreshes the tree.
|
protected Object |
getRoot()
Overridden because the input of this viewer is not identical to the root of the tree.
|
IStructureCreator |
getStructureCreator()
Returns the structure creator or
null if no
structure creator has been set with setStructureCreator. |
String |
getTitle()
Reimplemented to get the descriptive title for this viewer from the
IStructureCreator. |
protected void |
handleDispose(DisposeEvent event)
Called on the viewer disposal.
|
protected void |
initialSelection()
This hook method is called from within
inputChanged
after a new input has been set but before any controls are updated. |
protected void |
inputChanged(Object input,
Object oldInput)
Internal hook method called when the input to this viewer is
initially set or subsequently changed.
|
protected void |
postDiffHook(Differencer differencer,
IDiffContainer root)
This method is called from within
diff() after the difference
tree has been built. |
protected void |
preDiffHook(IStructureComparator ancestor,
IStructureComparator left,
IStructureComparator right)
This method is called from within
diff() before the difference
tree is being built. |
protected void |
propertyChange(PropertyChangeEvent event)
Tracks property changes of the configuration object.
|
void |
setStructureCreator(IStructureCreator structureCreator)
Configures the
StructureDiffViewer with a structure creator. |

StructureDiffViewer with a structure creator.
The structure creator is used to create a hierarchical structure

ViewerThe default implementation does nothing. Subclassers may override this method to do something when a viewer's input is set. A typical use is populate the viewer.

after a new input has been set but before any controls are updated.
This default implementation calls navigate(true)
to select and expand the first leaf node.

they want to call the inherited method.initialSelection in class DiffTreeViewerprotected void handleDispose(DisposeEvent event)
