// 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<T> * is used rather than T *.
|
|
|
|
// Another key part of the implementation is the smartptr feature:
|
|
// %feature("smartptr") T { shared_ptr<T> }
|
|
// This feature marks the class T as having a smartptr to it (the shared_ptr<T> type). This is then used to
|
|
// support smart pointers and inheritance. Say class D derives from base B, then shared_ptr<D> is marked
|
|
// with a fake inheritance from shared_ptr<B> in the type system if the "smartptr" feature is used on both
|
|
// B and D. This is to emulate the conversion of shared_ptr<D> to shared_ptr<B> 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
