A compare container is used to represent any UI that can contain compare viewers.
A filter that can be applied during the comparison of documents that can be used to customize the detection of text differences via the compareFilter extension point.
A label provider that provides the label and image for the left, right and ancestor sides for a compare input being shown in compare/merge viewers.
Interface common to all objects that provide a means for registering for content change notification.
Common interface for objects with editable contents.
Common interface for objects with a modification date.
Interface that allow clients to navigate through the changes shown in a compare pane.
Interface common to all objects that provide a means for registering for property change notification.
Clients should use
Interface for getting the name, image, and type for an object.

A compare operation must be implemented as a subclass of CompareEditorInput. A CompareEditorInput runs a (potentially lengthy) compare operation under progress monitor control, creates a UI for drilling-down into the compare results, tracks the dirty state of the result in case of merge, and saves any changes that occured during a merge.
The NavigationAction is used to navigate (step) through the individual differences of a CompareEditorInput.
An instance of CompareConfiguration configures various UI aspects of compare/merge viewers like title labels and images, or whether a side of a merge viewer is editable. It is passed to the CompareEditorInput on creation.
When implementing a hierarchical compare operation as a subclass of
CompareEditorInput clients have to provide a tree of objects where each
node implements the interface
This interface is used by the hierarchical differencing engine
(org.eclipse.compare.structuremergeviewer.Differencer) to walk the tree.
In addition every leaf of the tree must implement the IStreamContentAccessor or IEncodedStreamContentAccessor interfaces in order to give the differencing engine access to its stream content and to its encoding (with IEncodedStreamContentAccessor).
The abstract class BufferedContent provides a default implementation for the IStreamContentAccessor and IContentChangeNotifier interfaces. Its subclass ResourceNode adds an implementation for the IStructureComparator and ITypedElement interfaces based on Eclipse workbench resources (org.eclipse.core.resources.IResource). It can be used without modification as the input to the differencing engine.
The ZipFileStructureCreator is an implementation of the org.eclipse.compare.structuremergeviewer.IStructureCreator interface and makes the contents of a zip archive available as a hierarchical structure of IStructureComparators which can be easily compared by the differencing engine (org.eclipse.compare.structuremergeviewer.Differencer). It is a good example for how to make structured files available to the hierarchical compare functionality of the Compare plugin.
The EditionSelectionDialog is a simple selection dialog where one input element can be compared against a list of historic variants (editions) of the same input element. The dialog can be used to implement functions like "Replace with Version" or "Replace with Edition" on workbench resources.
In addition it is possible to specify a subsection of the input element (e.g. a method in a Java source file) by means of a path. In this case the dialog compares only the subsection (as specified by the path) with the corresponding subsection in the list of editions. This functionality can be used to implement "Replace with Method Edition" for the Java language.
The EditionSelectionDialog requires that the editions implement the IStreamContentAccessor and IModificationDate interfaces. The HistoryItem is a convenience class that implements these interfaces for IFileState objects.
The CompareViewerPane is a convenience class which provides
a label and local toolbar for a compare viewer (or any other subclass of a
Its abstract subclass CompareViewerSwitchingPane supports dynamic viewer switching, that is the viewer installed in the pane is dynamically determined by the pane's input object. Both classes are useful if you want to use compare viewers outside the context of a compare editor, for example in a dialog or wizard.
A Splitter is an extension of a SashForm that supports nesting, maximizing of panes, and propagating the visibility state of panes.
The interface IStreamMerger defines a single operation for performing a three-way merge on three
input streams. The merged result is written to an output stream.
Clients must implement this interface when contributing new mergers to the
org.eclipse.compare.streamMergers extension point.
New IStreamMergers can be created for registered types with the createStreamMerger methods of CompareUI.
