// This is a helper file for shared_ptr and should not be included directly.
// The main implementation detail in using this smart pointer of a type is to customise the code generated
// to use a pointer to the smart pointer of the type, rather than the usual pointer to the underlying type.
// So for some type T, shared_ptr
* is used rather than T *.
// Another key part of the implementation is the smartptr feature:
// %feature("smartptr") T { shared_ptr }
// This feature marks the class T as having a smartptr to it (the shared_ptr type). This is then used to
// support smart pointers and inheritance. Say class D derives from base B, then shared_ptr is marked
// with a fake inheritance from shared_ptr in the type system if the "smartptr" feature is used on both
// B and D. This is to emulate the conversion of shared_ptr to shared_ptr in the target language.
// shared_ptr namespaces could be boost or std or std::tr1
// For example for std::tr1, use:
// #define SWIG_SHARED_PTR_NAMESPACE std
// #define SWIG_SHARED_PTR_SUBNAMESPACE tr1
