Examples of ASTRewrite

Infrastructure for modifying code by describing changes to AST nodes. The AST rewriter collects descriptions of modifications to nodes and translates these descriptions into text edits that can then be applied to the original source. The key thing is that this is all done without actually modifying the original AST, which has the virtue of allowing one to entertain several alternate sets of changes on the same AST (e.g., for calculating quick fix proposals). The rewrite infrastructure tries to generate minimal text changes, preserve existing comments and indentation, and follow code formatter settings. If the freedom to explore multiple alternate changes is not required, consider using the AST's built-in rewriter (see {@link org.eclipse.php.core.ast.nodes.Program#rewrite(IDocument,Map)}).

The following code snippet illustrated usage of this class:

 Document document = new Document("<?php class X {} ?>"); ASTParser parser = ASTParser.newParser(AST.JLS3); parser.setSource(doc.get().toCharArray()); Program cu = (Program) parser.createAST(null); AST ast = cu.getAST(); MethodDeclaration md = ast.newMethodDeclaration(); md.setName(ast.newName("foo")); ASTRewrite rewriter = ASTRewrite.create(ast); ClassDeclaration td = (ClassDeclaration) cu.statements().get(0); ITrackedNodePosition tdLocation = rewriter.track(td); ListRewrite lrw = rewriter.getListRewrite(cu, Program.METHODS_PROPERTY); lrw.insertLast(md, null); TextEdit edits = rewriter.rewriteAST(document, null); UndoEdit undo = edits.apply(document); assert "<?php class X {\n function foo() { } \n } ?>".equals(doc.get().toCharArray());

This class is not intended to be subclassed.
