| − | The C++ code generation is available in the extra plugins of Papyrus. Make sure to unselect "Group features by category" and install "Papyrus C++ profile, view and code generation (Incubation)". C++ code generation is also automatically installed with [Papyrus_Qompass Qompass].

| − | The C++ code generation comes with the following elements
| + | |
| − | | + | |
| − | * A C++ specific profile and a view simplifying the edition
| + | |
| − | * The code generator itself (enriched with the C++ profile)
| + | |
| − | * A CDT editor integration, allowing you to edit the code of a class in a CDT editor
| + | |

| − | == C++ profile ==
| + | |
| − | | + | |
| − | The C++ profile defines a set of stereotypes that add C++ specific information to a UML model. For instance, a parameter of an operation might be passed by value, reference or as a pointer. The latter can be specified via the stereotypes C_Cpp::Ref and C_Cpp::Ptr respectively.
| + | |
| − | | + | |
| − | In the sequence, we shortly describe all stereotypes in alphabetical order:

| − | | Array
| + | |
| − | | Parameter or Property
| + | |
| − | | Indicate array with a given multiplicity. Unlike the multiplicities in UML, the array size can be an arbitrary expression, it must not be directly an integer.
| + | |
| − | |-
| + | |
| − | | Const
| + | |
| − | | Operation, Property or Parameter
| + | |
| − | | Declare that an operation, property or parameter is constant. Refer to the C++ semantics

| − | |-
| + | |
| − | | External
| + | |
| − | | Classifier
| + | |
| − | | Indicate that no code should be generated for this classifier. Other classifiers will import this classifier with the include path specified in the "definition" attribute

| − | | ExternLibrary
| + | |
| − | | Package
| + | |
| − | | Mark a package as External Library. If an element of this package is used, the associated CDT project will be configured accordingly (include and library paths)

| − | | Friend

| − | | Operation or Dependency

| − | | Include
| + | |
| − | | Class, Package or PackageImport
| + | |
| − | | An arbitrary string that is added to header and body file. Although primarily intended for manual #include directives, it can be used for arbitrary definitions. The contents of the attribute "preBody" is added to a C++ body file before automatic #include statements, "body" after these.

| + | |
| − | | + | |
| − | After installation, you can import the plugin org.eclipse.papyrus.cpp.test into your workspace. Within, you can find a sample model called "TestCDTintegration". Once opened, you should see the following screen.
| + | |
| − | | + | |
| − | [[File:cdt-editor.png]]
| + | |
| − | | + | |
| − | The CDT editor appears within a tab of Papyrus. This enables a side-by-side view of model and code. The editor can be invoked via the context menu of a class, operation or transition (within a statechart). Synchronisation is done, when the CDT editor looses focus. When model elements change, e.g. is you rename an operation, the code is regenerated and an update is done. It should not be possible to get conflicting changes, since a change in the model implies that the focus is no longer on the textual editor, i.e. changes in the texteditor should be already in the model.
