Detailed Description
class OgreNewt::_DestructorCallback< DerivedClass >
helper class: OgreNewt-classes can derive from this class to implement a destructor-callback
Consider the following example: You delete a body thats part of joint, so newton deletes the joint, then you could still have a pointer to that joint. Using this pointer will fail, thats why you need a way to get to know, when an object gets deleted...

typedef std::function<void(DerivedClass*)> OgreNewt::_DestructorCallback< DerivedClass >::DestructorCallbackFunction |
destructor callback
This function is called, when the object is destroyed. It's only argument is a pointer to the instance currently destroyed
- Warning
- the pointer to the destroyed class instance is already invalid (the class is already destroyed!)

set the destructor callback
This specifies a custom callback that's called when this class is destroyed. If you are using a standard non-member function, or a static member function, you can simply pass a pointer to the function here.. like this: setDestructorCallback( &myCallbackFunction );
If you want to bind to a class member, you also need to pass a pointer to the class itself, using the std::bind system, like so: setDestructorCallback( std::bind( &MyClass::myCallback, (MyClass*)classInstance, std::placeholders::_1 ) ); (from outside the class) or: setDestructorCallback( std::bind( &MyClass::myCallback, this, std::placeholders::_1 ) ); (from inside the class).
You can also use: setDestructorCallback<>( &MyClass::myCallback, (MyClass*)classInstance ); (from outside the class) or: setDestructorCallback<>( &MyClass::myCallback, this ); (from inside the class). Note: Notice the "<>" after the function name.
