All C++ stereotypes are derived from «C++Element».

Constraints described in this chapter are for information only; syntax of these constraints must be checked with the Object Constraint Language interpreter.

Invisible stereotypes «C++Class», «C++Operation», «C++Parameter», «C++Attribute», «C++LiteralValue», «C++Include», «C++Generalization», and «C++TemplateParameter» are used only to store C++ language properties. These stereotypes and their tag definitions are used by the Domain Specific Language Customization framework.

 Here are the Stereotypes presented throughout the page:

C++ Stereotypes

C++Operation

«C++Operation» is an invisible stereotype used to include language properties for any C++ operation.

NameMeta ClassConstraints

C++Operation

Operation

Function Const

 void f() const;

Constraint: Only valid for member function (member functions are operators that are declared as members of a class)

 if isQuery then
 stereotype-
>select(name=’C++Global’)->isEmpty()
Tag definitionType and default valueDescriptions
inlineboolean[1]=false

Function Inline

      inline a();
throw exceptionC++ThrowType[1]=any

Exception specification:

If operation.raisedExpression is not empty, the expression throw

is generated.

 void f() throw(int); 

If operation.raisedExpression is empty and expression throw value

is none, then a expression throw without argument is generated.

 void f() throw () 

If operation.raisedExpression is empty and expression throw value

is any, it does not generate a Keyword throw.

 void f();
virtualboolean[1]=false

Function Virtual

 virtual a(); 

Constraint: Only valid for member function and non static

 stereotype-
