Namespaces

What is translated > File layout > Namespaces

There is an option, to create a namespace for each unit. In C++ header files the scope expressions are put in front of types and constants from other units and in the C++ implementation files according uses clauses are inserted.

Example:

unit Namespace1;

interface

type

PInteger = ^integer;

...

unit Namespace2;

interface

uses Namespace1;

type

PInt = PInteger;

implementation

const

_pint1 : PInteger = Nil;

_pint2 : PInt = Nil;

end.

Namespace2 is translated to the header:

#ifndef Namespace2H

#define Namespace2H

#include "Namespace1.h"

namespace Namespace2

{

typedef Namespace1::PInteger PInt;

}  // namespace Namespace2

#endif //  Namespace2H

and the implementation:

#include <vcl.h>

#pragma hdrstop

#include "Namespace2.h"

using namespace Namespace1;

namespace Namespace2

{

PInteger _pint1 = NULL;

PInt _pint2 = NULL;

}  // namespace Namespace2

Remarks:

The hpp-headers from C++Builder have a using clause at their end. That's why Delphi2Cpp II doesn't insert namespace qualifiers and using clauses for that files. The other way round: If a file has the name of a VCL unit, an according uses clause is inserted.
