[news.eclipse.tools.jdt] Re: Using the ASTParser for parsing an expressi

[judith.wiesinger@xxxxxxxxxxxxxxx (Judith Wiesinger)]

Problem solved:
I forgot that further things had to be set in order that the source is 
treated as compilation unit.
- setProject
- setCompilerOptions
- setUnitName
not to forget to setKind to ASTParser.K_COMPILATION_UNIT.


   public void testASTParsing() throws JavaModelException {
       ASTParser parser = ASTParser.newParser(AST.JLS3);
       // set source
       String source = 
           "import java.util.ArrayList;"
           + "import java.util.List;"
           + "class MyClass {\n" 
           + "public void myMethod() { \n"
           + "  List<Object> myList = new ArrayList<Object>(); \n"
           + "  String s; \n"
           + "  s = myList.get(0).toString(); \n"
           + "}"
           + "}"
       ;     
       parser.setSource(source.toCharArray());
       // set project
       IProject project = 
ResourcesPlugin.getWorkspace().getRoot().getProject(MY_PROJECT_NAME);
       IJavaProject javaProject = JavaCore.create(project);
       boolean exists = javaProject.exists();
       parser.setProject(javaProject);
       
       parser.setCompilerOptions(javaProject.getOptions(true));
       parser.setUnitName("MyClass");
       parser.setKind(ASTParser.K_COMPILATION_UNIT);
       
       parser.setResolveBindings(true);
       
       ASTNode node = parser.createAST(null);
       CompilationUnit cu = (CompilationUnit) node;
       TypeDeclaration type = (TypeDeclaration) cu.types().get(0);
       MethodDeclaration method = type.getMethods()[0];
       
       Block block = method.getBody();
       List<Statement> statements = block.statements();
       for (Statement stmt : statements) {
           if (stmt instanceof ExpressionStatement) {
               ExpressionStatement exprStmt = (ExpressionStatement) stmt;
               ITypeBinding typeBind = 
                    exprStmt.getExpression().resolveTypeBinding();
               String typeName = typeBind.getQualifiedName();
           }
       }
   }
