Description
Interface Summary | |
IContentChangeListener | An IContentChangeListener is informed about content changes of a
IContentChangeNotifier . |
IContentChangeNotifier | Interface common to all objects that provide a means for registering for content change notification. |
IEditableContent | Common interface for objects with editable contents. |
IModificationDate | Common interface for objects with a modification date. |
IPropertyChangeNotifier | Interface common to all objects that provide a means for registering for property change notification. |
IStreamContentAccessor | An IStreamContentAccessor object represents a set of bytes which can be
accessed by means of a stream. |
ITypedElement | Interface for getting the name, image, and type for an object. |
IViewerCreator | A factory object for Viewer . |
Class Summary | |
BufferedContent | Abstract implementation for a buffered IStreamContentAccessor . |
CompareConfiguration | A CompareConfiguration object
controls various UI aspects of compare/merge viewers like
title labels and images, or whether a side of a merge viewer is editable. |
CompareEditorInput | A compare operation which can present its results in a special editor. |
CompareUI | The class CompareUI defines the entry point to initiate a configurable
compare operation on arbitrary resources. |
CompareViewerPane | A CompareViewerPane is a convenience class which installs a
CLabel and a Toolbar in a ViewForm . |
CompareViewerSwitchingPane | A custom CompareViewerPane that supports dynamic viewer switching. |
EditionSelectionDialog | A dialog where one input element can be compared against a list of historic variants (editions) of the same input element. |
HistoryItem | A combination IFileState and ITypedElement that can be used as
an input to a compare viewer or other places where an IStreamContentAccessor
is needed. |
NavigationAction | A NavigationAction is used to navigate through the individual
differences of a CompareEditorInput . |
ResourceNode | A ResourceNode wrappers an IResources so that it can be used
as input for the differencing engine (interfaces IStructureComparator and ITypedElement )
and the ReplaceWithEditionDialog (interfaces ITypedElement and IModificationDate ). |
ZipFileStructureCreator | This implementation of the IStructureCreator interface
makes the contents of a zip archive available as a
hierarchical structure of IStructureComparator s. |
Provides support for performing structural and textual compare operations on arbitrary data and displaying the results.
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
org.eclipse.compare.structuremergeviewer.IStructureComparator.
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
interface in order to give the differencing engine access to its stream content.
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
JFace Viewer).
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.
