C++ namespaces generation with packages

[grand.titus]

Hi

I have a very simple project:
---Class Model [set as Namespace Root]
------Package1 [NOT set as Namespace Root]
---------Class1 with an attribute c2:Class2
------Package2 [NOT set as Namespace Root]
---------Class2

When I generate the C++ code, I expect to get a file Class1.h with something like:

Code: [Select]


using namespace Package2;

namespace Package1
{
  class Class1
  {
     public:
        Class1();
        virtual ~Class1();
     private:
        Class2 c2;
  };
}

But what I really get is:

Code: [Select]


#include "Class2.h"

class Class1
{
  public:
     Class1();
     virtual ~Class1();
  private:
     Class2 c2;
};


In fact, EA packages are not transformed into C++ namespaces.

Thanks in advance

PS: EA version : 6.5.797

Is Class Model really a Class?  If so, then that's likely to be the problem (although I can't see how you can set a Class to a Namespace Root).

Also check that both packages have the context menu item Set as Namespace Root (and not Clear Namespace Root).

Finally check the Settings|Namespaces... entries.

HTH,

Open the options dialog (Tools | Options) to the C++ page.

You'll find an option 'Generate Namespaces' that will be false.

Thanks, I've not seen this option. Now it works.

I get the code:

Code: [Select]


#include "Class2.h"
namespace Package1
{
class Class1
{
public:
Class1();
virtual ~Class1();
Package2::Class2 get();
private:
Package2::Class2 c2;
};
}

I am glad with that, but is it possible to use the instruction "using namespace ...;"?
In particular, can I put "using namespace std;" at the head of ech file?



I also wonder if it is possible to generate sources into a directory "src" rather than "Class Model"? In order to get this hierarchy:

Code: [Select]


-src
.+--Package1
.|..+--Class1.h
.|..+--Class1.cpp
.+--Package2
....+--Class2.h
....+--Class2.cpp

rather than:

Code: [Select]


-Class Diagram
.+--Package1
.|..+--Class1.h
.|..+--Class1.cpp
.+--Package2
....+--Class2.h
....+--Class2.cpp

Either add it to each class headers field, or add it to the Import Section template.

I guess you're doing a package generation, and auto-generating the files.  As the top level package is included in the path being generated you have two options.
Rename "Class Model" to "src" so that when generating you get that package, or generate each of the subpackages separately into the src directory.

Either add it to each class headers field, or add it to the Import Section template.

Finally, I have added:

• "using namespace std;" into the Import Section template
  
• "using namespace Package2;" into the headers and imports fields of the Generate Code dialog box of the class Class1.
  

These two instructions are added in the right place in *.h and *.cpp. But EA doesn't take care of "using namespace Package2;" and continues to add "Package2::" before "Class2". Is it possible to get round this problem?

[Eve]

Only by further modification of the templates.  They assume the need to include the namespace qualifier (as the using statement isn't generated by default) so you'll need to replace the %RESOLVE_QUALIFIED_TYPE("::", "int")% call with %attType% (or opReturnType etc)

Thanks for your answer.
Unfortunately manipulating template transformation code seem to be complex for me.
