Imported C++ registered package [message #1760974]

I imported the C++ STL registered package into a project and added a property, s, of type string to a class. Then I generated the code.

The generated .h file contains this:

class myHelloWorldClass {
public:
	/**
	 * 
	 */
	string s;

	/**
	 * 
	 */
	void run();

};

The problem is that the type should be "std::string" instead of just "string" so the code will not compile as is.

The workaround is to add "using namespace std;" to the header but this should not be necessary. Is there another way?

I understand that this library is still a work in progress and the bugzilla improvement issue https://bugs.eclipse.org/bugs/show_bug.cgi?id=496934 is still in the NEW state.

Also I would like to help fix this and work on the STL package if someone will point me in the right direction.

PS This is with version 2.0.3.201703080851.

The ExtLibrary stereotype already supports the use of qualified names via the "prefix" attribute. However, this attribute is not set to "std::" in the STL model library and there is an error in the evaluation of this attribute. I will correct this two problems asap.

Excellent. Do you think these fixes will be in the May release?

Yes, the fix should be in the latest build now and the release is planned for the beginning of next week.

I am a beginner about Papyrus.
I need to make a property with std::string type in a class.
But I can't find std::string in type dialog because there are UMLRT-RTS and AnsiCLibrary.
I guess that if I import C++ registered package, I will find std::string in type dialog.
Is it right?
If it is right, Can you show me where to find C++ registered Package and how to import C++ registered Package.

Hi,

Since you have the choice between the UMLRT-RTS and the Ansi-C library, you have probably Papyrus-RT installed.
The STL library (quite limited though). is part of Papyrus SW designer which you can install either via the market-place or its update-site (neon or oxygen): http://download.eclipse.org/modeling/mdt/papyrus/components/designer/
While Papyrus-RT targets a specific modeling approach dedicated for real-time systems, Papyrus SW Designer is a bit broader. After you installed SW designer, have a look at the installed examples (File->New->Example)

Since Papyrus-RT seems to be involved, I should mention that the STL is not supported by its code generatorand we therefore do not provide a type library for it.

We currently only support the ANSI C types and the UML primitive types, each having their own library that can be imported.

The UML type library does contain a "String" type that the code generator converts to "char *".

Please note that if you are using Papyrus-RT, there is a dedicated Papyrus-RT forum available.

Is this what you are looking for?

I have found the way to std::string as variable type of class attribute.
I applied AttributeProperties to the variable of a class and set std::string to type:String of AttributeProperties.
I don't have any problem until now.
Is it correct to use std::string like this?

Hi,

AttributeProperties is a stereotype of the Papyrus-RT C++ profile and is taken into account by the Papyrus-RT code generator. The use of the STL model library (coming with Papyrus-SW designer) in Papyrus-RT has not been intended, but seems to be ok - if you apply the additional stereotype.

If you use the code generation from Papyrus SW designer, you just type your class attribute with "string" from the STL model library, i.e. you don't need this stereotype.
