Detailed Description

template<typename T>
class Dali::IntrusivePtr< T >

Templated intrusive pointer class.

Uses the Dali:RefObject type with actual reference counting. The object is responsible for destroying itself.

Since:
2.4, DALi version 1.0.0

Member Typedef Documentation

template<typename T>
typedef void(IntrusivePtr::* Dali::IntrusivePtr< T >::BooleanType)() const

Pointer-to-member type.

Objects can be implicitly converted to this for validity checks.

Constructor & Destructor Documentation

template<typename T>
Dali::IntrusivePtr< T >::IntrusivePtr ( )

Standard constructor to unassigned object.

Since:
2.4, DALi version 1.0.0
template<typename T>
Dali::IntrusivePtr< T >::IntrusivePtr ( T *  p)

Constructor to attach existing object.

Since:
2.4, DALi version 1.0.0
Parameters:
[in]pPointer to object
template<typename T>
template<typename U >
Dali::IntrusivePtr< T >::IntrusivePtr ( IntrusivePtr< U > const &  rhs)

Copy constructor.

Since:
2.4, DALi version 1.0.0
Parameters:
[in]rhsConst reference to an IntrusivePtr
Template Parameters:
UReference counter object type

Member Function Documentation

template<typename T>
T* Dali::IntrusivePtr< T >::Detach ( )

Detaches pointer from intrusive ptr counting.

Use with care.

Since:
2.4, DALi version 1.0.0
Returns:
Pointer to reference counted object
template<typename T>
T* Dali::IntrusivePtr< T >::Get ( ) const

Gets pointer to reference counted object.
