Can I prevent nested deprecated method calls from warnings?
I have some library code that has legacy code that I would like to move away with. For this, I began to mark deprecated methods as deprecated. Where these methods call each other, I get deprecation warnings that I would rather not see (new functionality means you only need one call since there are fewer internals for how the classes work).
Is there a way to suppress the rejection warning for a call from OldMethod
to OldMethodHelper
? .. or a better way to do it at all?
For example (in MyClass.h
):
public ref class MyClass
{
public:
[Obsolete]
void OldMethodHelper();
[Obsolete]
void OldMethod();
void NewMethod();
};
In MyClass.cpp
:
void MyClass::OldMethodHelper()
{
// Some old helper method that called both from within this class and externally.
}
void MyClass::OldMethod()
{
OldMethodHelper(); // I don't want this call to raise a deprecation warning.
}
void MyClass::NewMethod()
{
// A new method which replaces the calls to both of the previous methods.
}
The code is called like this:
int main(array<System::String ^> ^args)
{
Console::WriteLine(L"Hello World");
MyClass m;
m.OldMethodHelper(); // This should raise a deprecation warning.
m.OldMethod(); // This should raise a deprecation warning.
m.NewMethod();
return 0;
}
Edit . I found another SO post that suggested using #pragma warning(disable: 4996)
, but this seems like a bit of a clumsy way to approach me:
void MyClass::OldMethod()
{
#pragma warning(push)
#pragma warning(disable: 4996) //4996 for _CRT_SECURE_NO_WARNINGS equivalent
OldMethodHelper(); // I don't want this call to raise a deprecation warning.
#pragma warning(pop)
}
Edit2 . Made some fixes / clarifications to the sample code.

Without proof, perhaps a macro can help here. Easier to show than to explain:
MyClass.h
---------
#ifndef MYCLASS_DEPRECATE
#define MYCLASS_DEPRECATE [Obsolete]
#endif
class MyClass
{
MYCLASS_DEPRECATE void OldMethodHelper();
...
}
MyClass.cpp
-----------
#define MYCLASS_DEPRECATE
#include "MyClass.h"
// The rest of the code
