Public Member Functions
	SmartI ()
	Default constructor initializes to NULL interface.
	SmartI (TInterface *iInterface)
	Constructor won't do an extra AddRef() on construction but will Release() on destruction.
	SmartI (const TSelf &iOther)
	Copy constructor performs AddRef() on interface.
	SmartI (TSelf &&iOther) noexcept
	Move constructor.
	~SmartI ()
	Destructor performs Release() on interface.
void	reset ()
	Reinitialize to NULL interface.
void	reset (TInterface *iInterface)
	Reinitialize to an interface, performs no AddRef on new interface, but will Release() it in destructor.
TSelf &	operator= (const TSelf &iOther)
	assign the SmartI to another one, performing AddRef() on interface.
TSelf &	operator= (TSelf &&iOther) noexcept
	Move assignment.
TPointer	get () const
	return pointer to interface
TPointer	operator-> () const
	access pointee as a pointer
TAddress	address ()
	access address of interface pointer.
bool	isEmpty () const
	return true if pointer doesn't own any interface.
bool	operator! () const
	return true if pointer doesn't own any interface (same as isEmpty).
	operator bool () const
	evaluates to true if pointer owns an interface (only in boolean context)
void	swap (TSelf &iOther)
	exchange the pointees (and there reference counts) between two shared pointers

Detailed Description

template<typename I>
class lass::util::SmartI< I >

smart pointer to COM interfaces

Author

Bram de Greve [Bramz]

Requirements for COM interface

COM interface I must implement two methods AddRef() and Release():

• AddRef() should increase reference count to interface
• Release() should decrease reference count

Member Function Documentation

reset() [1/2]

template<typename I>

void lass::util::SmartI< I >::reset ( )

inline

Reinitialize to NULL interface.

Performs Release() on old interface.

Definition at line 127 of file smart_i.h.

References swap().

reset() [2/2]

template<typename I>

void lass::util::SmartI< I >::reset ( TInterface * iInterface )

inline

Reinitialize to an interface, performs no AddRef on new interface, but will Release() it in destructor.

Performs Release() on old interface.

Definition at line 137 of file smart_i.h.

References swap().

isEmpty()

template<typename I>

bool lass::util::SmartI< I >::isEmpty ( ) const

inline

return true if pointer doesn't own any interface.

Returns

this->get() == 0

Definition at line 186 of file smart_i.h.

operator!()

template<typename I>

bool lass::util::SmartI< I >::operator! ( ) const

inline

return true if pointer doesn't own any interface (same as isEmpty).

Returns

this->get() == 0.

Definition at line 194 of file smart_i.h.

operator bool()

template<typename I>

lass::util::SmartI< I >::operator bool ( ) const

inlineexplicit

evaluates to true if pointer owns an interface (only in boolean context)

Returns

this->get() != 0.
