emf4cpp's Issues

Generate java doc like documentation headers

Is there a way to generate default documentation that is generated in the .ecore -> java process?

unable to resolve the reference

using basic company example during deserializing created UMU.xmi file unable to get reference from one of the fields:

Company_ptr umu (::ecore::as< Company >(eobj));
const auto& lDepartments = umu->getDepartments();
std::cout<<lDepartments.size()<<std::endl;
const auto& manager = lDepartments[0]->getManager();

getManager() return NULL ptr;

UMU.xmi:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<company:Company xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:company="http:///com.example.company.ecore" name="UMU">
<departments number="8515" manager="//@departments.0/@employees.1">
<employees name="Andres Senac">
<phonebookEntry/>
</employees>
<employees name="Diego Sevilla"/>
</departments>
</company:Company>

edited for parsing basic example:

int main(int argc, char* argv[])

    CompanyPackage_ptr companyPackage = CompanyPackage::_instance();
    CompanyFactory_ptr companyFactory = CompanyFactory::_instance();

    {
		Company_ptr umu ( companyFactory->createCompany());

        Department_ptr catedraSAES = companyFactory->createDepartment();
        catedraSAES->setNumber(8515);

        Employee_ptr asenac = companyFactory->createEmployee();
        asenac->setName("Andres Senac");

		/* Check if a containment relation properly sets the eContainer() attribute. */
        catedraSAES->getEmployees().push_back(asenac);
		assert( asenac->eContainer() == catedraSAES );

		catedraSAES->getEmployees().remove(asenac);
		assert( asenac->eContainer() == nullptr );

        catedraSAES->getEmployees().push_back(asenac);

Ambiguous operations String getFQN(EClassifier this,String separator) and String getFQN(EOperation this,String separator) for param types [Void, String]

Hi,

when trying to generate C++ files for the Xbase.ecore meta model, I'm getting the following exception:

I use the following command to generate the C++ classes:

java -jar "org.csu.emf4cpp.generator_2.0.0.jar" -o ../../src/ecore Xbase.ecore

Has anyone an idea why this exception occurs? The causing call should be this one: https://github.com/catedrasaes-umu/emf4cpp/blob/master/org.csu.emf4cpp.generator/src/template/EClassHPP.xpt#L52

I'm not sure if there's a problem with the Xbase meta-model or if I configured the emf4cpp-generator the wrong way.

Thanks in advance for your help!

Mario

cannot convert ‘ecore::EClass’ to ‘ecore::EObject’ for argument ‘1’ to ‘void ecore::intrusive_ptr_release(ecore::EObject*)’

I have tried creating a simple model then generated using the generator available with the "Downloads" section of your project.

But I end up always with this error:

cannot convert ‘ecore::EClass*’ to ‘ecore::EObject*’ for argument ‘1’ to ‘void ecore::intrusive_ptr_release(ecore::EObject*)’

Trying to get the library running with Visual Studio 2019

Hi there,
I was successfully compiling the library with VS2019.
But I'm getting runtime problems during the initialization of EcorePackage and EcoreFactory.
(Please note the change in line 179, which was Object_ptr ... casting between intrusive pointers can be problematic for derived classes right?

I also noticed that the generated classes do not contain any code for _inverseAdd and _inverseRemove.
Is there any known problem with this 'reverse setup' which Ecore is using. I know from the Java implementation
these two way references between two objects.

This is the function in my Ecore beeing generated:

PS) I have already fixed some missing code for handling more complex ecores (with inheritance over multiple ecores).
however I would wait for a running version before I'm sure this is the fix...

Issues with merged pull request #5

Dear Team,

after some time with no response from @qvitech we suggest to revert pull request #5 completely for the following reasons:

The emf4cpp generator cannot be built: org.csu.emf4cpp.generator/src/template/PackageImpl.xpt, line 51 calls the undefined function getFQN2(). Hence the jar file of the generator cannot be built.
Code was added to the ecore implementation outside of a PROTECTED REGION. The ecore implementation itself will be generated during the bootstrap process of the library. Any code outside of PROTECTED_REGIONs will be removed automatically.
The changes in org.csu.emf4cpp.generator/src/template/EClassImplCPP.xpt may seem like an innocent optimization, but it removes the possibility to set/get attributes of base classes via the generic eSet()/eGet() methods of derived instances. Actually we do not see how serialization or deserialization of class hierarchies continues to work at all after this change.

Regards,
Matthias.

Emf4Cpp support XMI

Does EMF4CPP support XMI? Since I only found XMLResourceFactory but not a XMIResourceFactory.

Custom EDatatype not supported

Hello Team,

In the ecore I had created one EDatatype of Input stream with instanceTypeName = java.io.stream which is working in Java generated code but with equivalent C++ instanceTypeName it is not working. Can you provide a solution?

JAVA:
<eClassifiers xsi:type="ecore:EDataType" name="InputStream" instanceTypeName="java.io.stream"/>

C++:
<eClassifiers xsi:type="ecore:EDataType" name="InputStream" instanceTypeName="std::istream"/>

Resolving "xmi" namespace

Hi,

I'm trying to parse a XMI file which has a xmi:XMI root node (like shown in the example at https://www.euclideanspace.com/software/information/xml/xmi/index.htm):

<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:types="http://www.eclipse.org/xtext/common/JavaVMTypes" xmlns:xbase="http://www.eclipse.org/xtext/xbase/Xbase">
...
</xmi:XMI>

If I try to parse this file, I get the following error:

terminate called after throwing an instance of 'std::logic_error'
what(): missing package: xmi
Aborted (core dumped)

I think that the reason is that there's no meta model found in the MetaModelRepository for the namespace xmi.

This is the code I'm using to register the meta models in the repository:

::ecorecpp::MetaModelRepository_ptr repository = ::ecorecpp::MetaModelRepository::_instance();

::ecore::EcorePackage_ptr ecorePackage = ::ecore::EcorePackage::_instance();
repository->load(ecorePackage);

::types::TypesPackage_ptr typesPackage = ::types::TypesPackage::_instance();
repository->load(typesPackage);

::xbase::XbasePackage_ptr xbasePackage = ::xbase::XbasePackage::_instance();
repository->load(xbasePackage);

Do I have to add another package to the registry to be able to parse XMI files with a xml:XMI root node?

Thank you in advance!

Best regards,
Mario

read model file based on created meta-model

I created a meta-model, generated the corresponding cpp code, created an xml file corresponding to my meta-model with the extension ".test_meta_model" and want to read this file. What are the steps?
