Steinberg::FUnknownImpl Namespace Reference

Namespaces
namespace	Detail

Classes
struct	Destroyer
	Common destroyer policy for ski object instances. More...
struct	Directly
	This struct is used to group a list of interfaces from which should be inherited and which should be available via the queryInterface method. More...
struct	HideIIDBase
	A base class which hides the FUnknown::iid static var. More...
class	ImplementsImpl
class	ImplementsImpl< Base, Indirectly< IndirectInterfaces... >, Directly< DirectInterfaces... > >
class	ImplementsImpl< BaseClass, Directly< I, DirectIFs... >, Indirectly< IndirectIFs... > >
	This class implements the required virtual methods for the U::Unknown class. More...
struct	Indirectly
	This struct is used to group a list of interfaces from which should not be inherited but which should be available via the queryInterface method. More...
struct	UID
	This class provides a compile-time uid and enables interfaces to specify a UID as a simple typedef. More...

Typedefs
using	Unknown = FUnknown
	Typedef to keep everything in this namespace. More...
template<typename BaseClass , typename D , typename I = Indirectly<>>
using	Extends = ImplementsImpl< BaseClass, D, I >
	This typedef enables using a custom base class with the interface implementation. More...
template<typename D , typename I = Indirectly<>>
using	Implements = ImplementsImpl< Detail::QueryInterfaceEnd< Detail::RefCounted >, D, I >
	This typedef provides the interface implementation. More...
template<typename D , typename I = Indirectly<>>
using	ImplementsNonDestroyable = ImplementsImpl< Detail::QueryInterfaceEnd< Detail::NonDestroyable >, D, I >
	This typedef provides the interface implementation for objects which should not be destroyed via FUnknown::release (like singletons). More...

Functions
template<typename T >
const TUID &	getTUID ()
template<typename I >
IPtr< I >	cast (Unknown *u)
	Checks if the given Unknown can provide the specified interface and returns it in an IPtr. More...
template<typename I , typename S , typename T , typename U >
IPtr< I >	cast (ImplementsImpl< S, T, U > *u)
	Casts to Unknown* and then to the specified interface. More...
template<typename I , typename T >
IPtr< I >	cast (const IPtr< T > &u)
	Casts to Unknown* and then to the specified interface. More...

Typedef Documentation

Unknown

using Unknown = FUnknown

Typedef to keep everything in this namespace.

Extends

using Extends = ImplementsImpl<BaseClass, D, I>

This typedef enables using a custom base class with the interface implementation.

Implements

using Implements = ImplementsImpl<Detail::QueryInterfaceEnd<Detail::RefCounted>, D, I>

This typedef provides the interface implementation.

ImplementsNonDestroyable

using ImplementsNonDestroyable = ImplementsImpl<Detail::QueryInterfaceEnd<Detail::NonDestroyable>, D, I>

This typedef provides the interface implementation for objects which should not be destroyed via FUnknown::release (like singletons).

Function Documentation

getTUID()

const TUID & Steinberg::FUnknownImpl::getTUID

(

)

Returns

the TUID for an interface.

cast() [1/3]

IPtr< I > Steinberg::FUnknownImpl::cast

(

Unknown *

u

)

Checks if the given Unknown can provide the specified interface and returns it in an IPtr.

Returns

an IPtr pointing to an instance of the requested interface or nullptr in case the object does not provide the interface.

cast() [2/3]

IPtr< I > Steinberg::FUnknownImpl::cast

(

ImplementsImpl< S, T, U > *

u

)

Casts to Unknown* and then to the specified interface.

cast() [3/3]

IPtr< I > Steinberg::FUnknownImpl::cast

(

const IPtr< T > &

u

)

Casts to Unknown* and then to the specified interface.
