I am attempting to programmatically create an operation on an interface in my model. I have been successful adding the operation to the interface, and adding parameters to the operation, but I am having difficulty setting the parameter type. I am kind of new at this, so please forgive me if I am missing something basic.

For example, the operation I was trying to create on the interface has the signature:

bool recordExists( int recordId );

I was hoping to be able to do something like this (using a Package in a model named 'aPackage'):

// add an interface to the package
Interface iRecordManager = (Interface)aPackage.createOwnedInterface("recordManager");

// add an operation to the interface
Operation recordExists = (Operation)iRecordManager.createOwnedOperation("recordExists ", null, null, null);

Now I would like to add the parameter and the return value to the operation, doing something like this:

Parameter param = (Parameter)recordExists.createOwnedParameter("recordId", null);
param.setVisibility(VisibilityKind.PRIVATE_LITERAL);
param.setType(null);
Parameter retParam = (Parameter)recordExists.createReturnResult("ret", null);

How do I specify the type to param.setType(Type) and recordExists.createReturnResult(String, Type)? I've done a lot of searching on how to do this, but I haven't been able to find anything.

Hope someone could point me in the right direction.

Thanks, all --

Ian

You can create the types you will need, or import them from a different model.

For creating your own types, createOwnedPrimitiveType, createOwnedClass, createdOwnedEnumeration etc. In your case, I guess you want them to be primitive types.

For the Type hierarchy, see:

http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse. uml2.doc/references/javadoc/org/eclipse/uml2/uml/class-use/T ype.html

For an example in TextUML, see:

package UML2Example;

primitive int;
primitive bool;

interface RecordManager 
    operation recordExists(recordId : int) : bool;
end;
        
end.

Hope it helps,

Thank you very much for pointing me to the Type hierarchy, I was able to use getOwnedType(String) to get the type reference I needed.

I'm also going to check out TextUML, looks very interesting.

Thanks again,

Ian
