- * A CompareEditorInput defines methods for the following sequence steps: - *

- * The Compare plug-in's openCompareEditor method takes an ICompareEditorInput - * and starts sequencing through the above steps. If the compare result is not empty a new compare editor - * is opened and takes over the sequence until eventually closed. - *

- * The prepareInput method should contain the - * code of the compare operation. It is executed under control of a progress monitor - * and can be canceled. If the result of the compare is not empty, that is if there are differences - * that needs to be presented, the ICompareEditorInput should hold onto them and return them with - * the getCompareResult method. - * If the value returned from getCompareResult is not null - * a compare editor is opened on the ICompareEditorInput with title and title image initialized by the - * corresponding methods of the ICompareEditorInput. - *

- * Creation of the editor's SWT controls is delegated to the createContents method. - * Here the SWT controls must be created and initialized with the result of the compare operation. - *

- * If merging is allowed, the modification state of the compared constituents must be tracked and the dirty - * state returned from method isSaveNeeded. The value true triggers a subsequent call - * to save where the modified resources can be saved. - *

- * The most important part of this implementation is the setup of the compare/merge UI. - * The UI uses a simple browser metaphor to present compare results. - * The top half of the layout shows the structural compare results (e.g. added, deleted, and changed files), - * the bottom half the content compare results (e.g. textual differences between two files). - * A selection in the top pane is fed to the bottom pane.

- * In the three-way compare case ranges of differing lines are highlighted and framed - * with different colors to show whether the difference is an incoming, outgoing, or conflicting change. - * The TextMergeViewer supports the notion of a current "differing range" - * and provides toolbar buttons to navigate from one range to the next (or previous). - *

- * If there is a current "differing range" and the underlying document is editable - * the TextMergeViewer enables actions in context menu and toolbar to - * copy a range from one side to the other side, thereby performing a merge operation. - *

- * In addition to a line-by-line comparison the TextMergeViewer - * uses a token based compare on differing lines. - * The token compare is activated when navigating into - * a range of differing lines. At first the lines are selected as a block. - * When navigating into this block the token compare shows for every line - * the differing token by selecting them. - *

- * The TextMergeViewer's default token compare works on characters separated - * by whitespace. If a different strategy is needed (for example, Java tokens in - * a Java-aware merge viewer), clients can create their own token - * comparators by implementing the ITokenComparator interface and overriding the - * TextMergeViewer.createTokenComparator factory method). - *

- * Access to the TextMergeViewer's model is by means of an - * IMergeViewerContentProvider. Its getXContent methods must return - * either an IDocument, an IDocumentRange, or an IStreamContentAccessor. - * In the IDocumentRange case the TextMergeViewer - * works on a subrange of a document. In the IStreamContentAccessor case - * a document is created internally and initialized from the stream. - *

- * A TextMergeViewer can be used as is. However clients may subclass - * to customize the behavior. For example a MergeTextViewer for Java would override - * the configureTextViewer method to configure the TextViewer for Java source code, - * the createTokenComparator method to create a Java specific tokenizer. - * - * @see org.eclipse.compare.rangedifferencer.RangeDifferencer - * @see org.eclipse.jface.text.TextViewer - * @see ITokenComparator - * @see IDocumentRange - * @see org.eclipse.compare.IStreamContentAccessor - */ -public class TextMergeViewer extends ContentMergeViewer { - - private static final boolean DEBUG= false;

-Package Specification

- -The ContentMergeViewer is an abstract compare and merge viewer -with two side-by-side content areas and an optional content area for a -common ancestor (for three-way compare). Because the implementation makes -no assumptions about the content type it is a subclass responsibility to -deal with a specific type. Its subclass ImageMergeViewer in -package org.eclipse.compare.internal shows how to base a simple -mergeviewer for images on ContentMergeViewer. -

- -A ContentMergeViewer accesses its model by means of a content -provider which must implement the IMergeViewerContentProvider interface. -

- -The TextMergeViewer is the standard concrete subclass of -ContentMergeViewer for comparing and merging text content. -
-A text merge viewer uses the org.eclipse.compare.rangedifferencer.RangeDifferencer -to perform a textual, line-by-line comparison of two (or three) input documents. -For text lines that differ the TextMergeViewer uses an ITokenComparator -to find longest sequences of matching and non-matching tokens. -The TextMergeViewer's -default token compare works on characters separated by whitespace. If a -different strategy is needed (for example, Java tokens in a Java-aware -merge viewer), clients can create their own token comparators by implementing -the ITokenComparator interface. -

The TextMergeViewer not only works on whole documents but on -subranges of documents too. In this case the viewer's input must be an -IDocumentRange instead of an IDocument. - - - diff --git a/bundles/org.eclipse.compare/compare/org/eclipse/compare/internal/AbstractViewer.java b/bundles/org.eclipse.compare/compare/org/eclipse/compare/internal/AbstractViewer.java deleted file mode 100644 index 84e8f945c..000000000 --- a/bundles/org.eclipse.compare/compare/org/eclipse/compare/internal/AbstractViewer.java +++ /dev/null @@ -1,38 +0,0 @@ -/******************************************************************************* - * Copyright (c) 2000, 2003 IBM Corporation and others. - * All rights reserved.

-Package Specification

- -The class CompareUI defines the entry point to initiate a configurable -compare operation on arbitrary resources. The result of the compare is -opened into a compare editor where the details can be browsed and edited -in dynamically selected structure and content viewers. -

- -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 -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 -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. -

- -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. - - - - diff --git a/bundles/org.eclipse.compare/compare/org/eclipse/compare/rangedifferencer/DifferencesIterator.java b/bundles/org.eclipse.compare/compare/org/eclipse/compare/rangedifferencer/DifferencesIterator.java deleted file mode 100644 index 0ad70b4f4..000000000 --- a/bundles/org.eclipse.compare/compare/org/eclipse/compare/rangedifferencer/DifferencesIterator.java +++ /dev/null @@ -1,77 +0,0 @@ -/******************************************************************************* - * Copyright (c) 2000, 2004 IBM Corporation and others. - * All rights reserved.

-Package Specification

- -The class RangeDifferencer finds longest sequences of matching and -non-matching comparable entities. Its implementation is based on -an objectified version of the algorithm described in: -A File Comparison Program, by Webb Miller and Eugene W. Myers, -Software Practice and Experience, Vol. 15, Nov. 1985. -

- -Clients must supply the input to the differencer as an implementation -of the IRangeComparator interface. -An IRangeComparator breaks the input data into a sequence -of entities and provides a method for comparing -one entity with the entity in another IRangeComparator. -

- -For example, to compare two text documents and find longest common -sequences of matching and non-matching lines, -the implementation of IRangeComparator -must break the document into lines and provide a method for testing -whether two lines are considered equal. -See org.eclipse.compare.internal.DocLineComparator for how this can be done. -

- -The differencer returns the differences among these sequences as an -array of RangeDifference objects. -Every single RangeDifference describes the kind of difference -(no change, change, addition, deletion) and the corresponding ranges -of the underlying comparable entities in the two or three inputs. - - - diff --git a/bundles/org.eclipse.compare/compare/org/eclipse/compare/structuremergeviewer/DiffContainer.java b/bundles/org.eclipse.compare/compare/org/eclipse/compare/structuremergeviewer/DiffContainer.java deleted file mode 100644 index b74d36e1b..000000000 --- a/bundles/org.eclipse.compare/compare/org/eclipse/compare/structuremergeviewer/DiffContainer.java +++ /dev/null @@ -1,107 +0,0 @@ -/******************************************************************************* - * Copyright (c) 2000, 2004 IBM Corporation and others. - * All rights reserved.

-Package Specification

- -The class Differencer is a differencing engine for hierarchically -structured data. It takes two or three inputs and performs a two-way or -three-way compare on them. -

- -If the input elements to the differencing engine implement the IStructureComparator -interface the engine recursively applies itself to the children of -the input element. Leaf elements must implement the org.eclipse.compare.IStreamContentAccessor -interface so that the differencer can perform a bytewise comparison on their contents. -

- -One good example for this is org.eclipse.compare.ResourceNode which implements both interfaces -(and more) for Eclipse workspace resources (org.eclipse.core.resources.IResource). -

- -Another example is the DocumentRangeNode which can be used to compare hierarchical structures -that are superimposed on a document, that is where nodes and leafs correspond to ranges in a document -(org.eclipse.compare.contentmergeviewer.IDocumentRange). -
-Typically DocumentRangeNodes are created while parsing a document and they represent -the semantic entities of the document (e.g. a Java class, method or field). -The two subclasses JavaNode (in org.eclipse.jdt.internal.ui.compare) -and PropertyNode (in org.eclipse.jdt.internal.ui.compare) are good examples for this. -

- -By default the differencing engine returns the result of the compare operation -as a tree of DiffNode objects. However, this can be changed by overriding -a single method of the engine. -

- -Every DiffNode describes the changes among the two or three inputs. -

- -A tree of DiffNodes can be displayed in a DiffTreeViewer. -The DiffTreeViewer requires that inner nodes of the tree implement -the IDiffContainer interface and leafs the IDiffElement interface. -

- -The typical steps to compare hierarchically structured data and to display -the differences would be to: -

    -
  • -map the input data into a tree of IStructureComparator and IStreamContentAccessors,
    • - -
  • -perform the compare operation by means of the Differencer, and
    • - -
  • -feed the differencing result into the DiffTreeViewer.
    • - -
- -The StructureDiffViewer is a specialized DiffTreeViewer -that automates the three steps from above. It takes a single input object -of type ICompareInput from which it retrieves the two or three -input elements to compare. Then it uses a IStructureCreator to -extract a tree of IStructureComparator and IStreamContentAccessor -from them. These trees are then compared with the differencing engine and -the result is displayed in the tree viewer. -
