Creating an operation redefinition

Redefining a standard operator

In C++, you can redefine standard operators, and for this, Objecteering C++ Developer lets you declare this construct. Coplien form defined on a newly created class contains such an example.

<<Cxx.Operator>> operator =(in value : OperatorRedefinition):OperationRedefinition

To redefine a standard equality operator, the following steps should be carried out:

· Create an operation.

· Add a <<Cxx.Operator>> stereotype to the operation.

· Set its name to "operator =".

· Add a <<Cxx.Name>> tagged value to the operation, and set "=" as its parameter.

Creating a cast operator

C++ also authorizes the creation of cast operators, to allow implicit conversion between types.

To define a cast operator, carry out the following steps:

· Create an operation.

· Add a <<Cxx.Name>> tagged value to the operation, and set the converted type as its parameter (like bool).

· Stereotype the operation using <<Cxx.Operator>>.

The generated code will be as follows:

operator bool();
