Detailed Description

template<typename T>
struct fsdk::Ref< T >

Smart pointer for reference counted objects.

Automatically calls retain/release and provides safety assertions.

Template Parameters

T	object interface (must be derived from IRefCounted)

Constructor & Destructor Documentation

template<typename T>

fsdk::Ref< T >::Ref ( T *  ptr )

inlineexplicitnoexcept

Initializes object pointer with ptr and retains a reference.

Note

this shares ownership.

Parameters

[in]

ptr

raw pointer to initialize with.

template<typename T>

fsdk::Ref< T >::Ref ( const Ref< T > &  other )

inline

Initializes object pointer with other and retains a reference.

Note

this shares ownership.

Parameters

[in]

other

pointer to initialize with.

template<typename T>

template<class D , typename = typename std::enable_if<std::is_convertible<D*, T*>::value>::type>

fsdk::Ref< T >::Ref ( const Ref< D > &  other )

inlineexplicit

Initializes object pointer with other and retains a reference.

Note

this shares ownership.

Parameters

[in]

other

pointer of derived template class to initialize with.

Member Function Documentation

template<typename T>

Ref& fsdk::Ref< T >::acquire ( T *  ptr )

inlinenoexcept

Template Parameters

S	target interface (must be relative to T)

template<typename T>

Ref& fsdk::Ref< T >::assign ( T *  ptr )

inlinenoexcept

Parameters

[in]

ptr

raw object pointer to assign.

template<typename T>

T** fsdk::Ref< T >::getInitReference ( )

inlinenoexcept
