Detailed Description

template<typename T>
class cppdb::ref_ptr< T >

This is a smart intrusive reference counting pointer that throws a error on empty access.

The T should follow these concepts:

   T::add_ref() // increases reference count
   IntegerType  T::del_ref() // decreases reference count and returns its current value
   static T::dispose(T *) // destroys the object

Constructor & Destructor Documentation

template<typename T>

cppdb::ref_ptr< T >::ref_ptr

(

T *

v = 0

)

[inline]

Default create a new object, if v is not null increases its reference count and stores it

template<typename T>

cppdb::ref_ptr< T >::~ref_ptr

(

)

[inline]

Dereference the object, if reference count goes to 0 destroys it calling T::dispose

template<typename T>

cppdb::ref_ptr< T >::ref_ptr

(

ref_ptr< T > const &

other

)

[inline]

Copy a pointer

Member Function Documentation

template<typename T>

T* cppdb::ref_ptr< T >::get

(

)

const [inline]

Get he pointer value, it may return NULL in case of empty pointer

template<typename T>

cppdb::ref_ptr< T >::operator bool

(

)

const [inline]

Cast to boolean type: check if the pointer is not empty in similar way as you check ordinary pointers.

template<typename T>

T& cppdb::ref_ptr< T >::operator*

(

)

const [inline]

Returns reference to object, throws cppdb_error if it is NULL

template<typename T>

T* cppdb::ref_ptr< T >::operator->

(

)

const [inline]

Returns pointer to object, throws cppdb_error if it is NULL

template<typename T>

ref_ptr const& cppdb::ref_ptr< T >::operator=

(

ref_ptr< T > const &

other

)

[inline]

Assign a pointer

template<typename T>

void cppdb::ref_ptr< T >::reset

(

T *

v = 0

)

[inline]

Reset the pointer with new value - old object is dereferenced new is added.
