Question
How do you achieve pointer (*) type modeling for argument types using JAVA API in IBM Rational Rhapsody?
Cause
You would like to use Java Application Programming Interfaces [API] code to automate the manual task to be performed with in Rational Rhapsody or to achieve something that is not possible through Rational Rhapsody GUI.
Answer
In order to achieve pointer (*) type modeling of argument types you can use the description field.
The following script leverages this idea of modeling argument types (using the description field) as pointer, constant, pointer pointer, etc and as per the modeling technique used specific argument properties are updated to generate the desired code.
The script understands the following modeling constructs (in the description field) for an argument:
- @Constant - constant type
- @Pointer - pointer type
- @*Pointer - pointer pointer type
- @*Constant - constant pointer type
- Absence of above constructs - default type
The workflow for achieving the desired code generation:
- Model the arguments in the model using the constructs as mentioned above
- Once the desired modeling technique is achieved run the java script
- Once the script execution is complete, generate the code
