## [Programming Language Information for Project]

In JUDE, programming language information including Java and C# is set in stereotypes, tagged values and attributes in models.

#### Programming language information

Project model (IModel) has tagged value to set the language information.

Language | Item | Tagged Value | Stereotype | Model Attribute | Model
Java | Java Project | [Key]jude.profile.java [Value]true/false | - | - | Project Model(IModel)
C# | C# Project | [Key]jude.profile.c_sharp [Value]true/false | - | - | Project Model(IModel)
C++ | C++ Project | [Key]jude.profile.c_plus [Value]true/false | - | - | Project Model(IModel)

#### How to recognize Java or C# (Class, Attribute, Operation)

Use the checkboxes in the language tab of the property view for class, attribute and operation. For example, Java checkbox is set to ON for class, A stereotype, "Java Class", will be set. (However, it will not displayed in the property view or diagram editor.)

Language | Model | Stereotype
Java | Class (IClass) | Java Class
Java | Attribute (IAttribute) | Java Attribute
Java | Operation (IOperation) | Java Method
C# | Class (IClass) | C# Class
C# | Attribute (IAttribute) | C# Attribute
C# | Operation (IOperation) | C# Method
C++ | Class (IClass) | C++ Class
C++ | Attribute (IAttribute) | C++ Attribute
C++ | Operation (IOperation) | C++ Method

#### Programming language information for Class, Attribute and Operation

In JUDE, programming language information including Java and C# is set in stereotypes, tagged values and attributes in models. In the language tab of the property view for class, attribute or operation, values for setup items are set to either tagged value, stereotype, model attribute.

#### How to get language information for project

Get project language information

        public void getLanguageInfomataion() {
            BasicModelEditor bme = ModelEditorFactory.getBasicModelEditor();
            IModel project = ProjectAccessorFactory.getProjectAccessor().getProject();

            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        private boolean isJavaProject(IModel project) {
            ITaggedValue[] tags = project.getTaggedValues();
            for (int i = 0; i < tags.length; i++) {
                ITaggedValue tag = tags[i];
                String key = tag.getKey();
                if ("jude.profile.java".eqauls(key) {
                    if ("true".equals(tag.getValue()) {
                        return true;

                }
            }
            return false;
        }

#### How to set language information for project

Set project language information

        public void testSetLanguageCSharp() throws ClassNotFoundException,
        InvalidEditingException, ProjectNotFoundException {
            BasicModelEditor bme = ModelEditorFactory.getBasicModelEditor();

            try {
                TransactionManager.beginTransaction();

                //Java:OFF
                bme.setLanguageJava(project, false);
                //C#:OFF
                bme.setLanguageCSharp(project, false);
                //Java:ON
                bme.setLanguageJava(project, true);
                //C#:ON
                bme.setLanguageCSharp(project, true);

                e.printStackTrace();
                fail();
            }
        }

#### Check if Java language information is set to class, or class is strictfp

        public void testGetJavaClassStrictfp() {
            BasicModelEditor bme = ModelEditorFactory.getBasicModelEditor();
            IModel project = ProjectAccessorFactory.getProjectAccessor().getProject();
            try {
                IElement element = getElement(project.getOwnedElements(), "Class0");
                if (isJavaClass(element)) {
                    System.out.println("Class0 has \"Java Class\" stereotype");
                    if (isJavaClassStrictfp(element)) {
                        System.out.println("Class0 has \"jude.java.strictfp\" TaggedValue");
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
                fail();
            }
        }

        protected INamedElement getElement(INamedElement[] elements, String elementName) {
            for (int i = 0; i < elements.length; i++) {
                if (elements[i].getName().equals(elementName)) {
                    return elements[i];
                }
            }
            return null;
        }

        private boolean isJavaClass(IElement element) {
            String[] sterotyopes = element.getStereotypes();
            for (int i =0 ; i < sterotyopes.length; i++) {
                if ("Java Class".equals(sterotyopes[i])) {
                    return true;

        }

        private boolean isJavaClassStrictfp(IElement element) {

                if ("jude.java.strictfp".equals(tag.getKey())) {
                    if ("true".equals(tag.getValue())) {
                        return true;
                    }
                }
            }
            return false;
        }

#### Set Java language information to project and class, then set strictfp to class

Set project language information

        public void testJavaAttributeStereotypeInClass() throws InvalidEditingException, ClassNotFoundException {
            BasicModelEditor bme = ModelEditorFactory.getBasicModelEditor();
            try {
                TransactionManager.beginTransaction();

                bme.setLanguageJava(project, true);
                IElement element = getElement(project.getOwnedElements(), "Class0");
                element.addStereotype("Java Class");
                bme.createTaggedValue(element, "jude.java.strictfp", "true");

                TransactionManager.endTransaction();

            } catch (InvalidEditingException e) {
                TransactionManager.abortTransaction();
                fail();
            }
        }
