C++ API UniginePtr bool() operator

[ggris]

It is pretty common for smart pointers nowadays to implement bool() operator. (See std:: for instance)
 
Maybe you could add to UniginePtr.h something like

/**
 * Test if the pointer object owns a resource
 */
UNIGINE_INLINE explicit operator bool() const {
    return (this->get() != nullptr);
}

With this you can use safe patterns like :

if (Unigine::Ptr<Something> ptr = methodToGetPtr())
{
    // ptr is guaranteed not to be nullptr here
    // Do something with ptr
    ...
}
// ptr is not defined here so cannot be misused.

Hi Guillaume,

 

Great suggestion! Added it to our internal TODO list.

 

Thanks!
