Inherit a class through smart pointer

[mce]

hi,

I am seeing a declaration something like this,

class MyTest: public boost::shared_ptr<SomeTest>
{


};

I am not sure why is it not

class MyTest: public SomeTest
{

};

What is the reason for the smart pointer here, we normally inherit a class, but why we need to inherit from a pointer to a class!?

without knowing more about what this is and does.... hard to tell.

the above simply derives a class from a shared_ptr of SomeTest...

possibly because mytest needs to refer to "no test" or needs to be able to dynamically indirectly bind to different tests.

note that because deriving from the smart pointer, mytest does NOT inherit the members of SomeTest, it inherits the members of the smart pointer class.

I am seeing a declaration something like this,

class MyTest: public boost::shared_ptr<SomeTest>
{
};

This is more straightforward and probably what was wanted to be achieved.

typedef boost::shared_ptr<SomeTest> MyTest;

Hi i got an error while i am building a dll library regarding the above:

class DLL_EXPORT MyTest: public boost::shared_ptr<SomeTest>
{
};

error C2562: 'boost::shared_ptr<T>:perator []' : 'void' function returning a value


if i remove the DLL_EXPORT, the compile error gone. How to solve this? I am exporting MyTest in a dll library.
