Members

Classes

Name	Description
ComPtrRef Class	Represents a reference to an object of type ComPtr<T>.
ComPtrRefBase Class	Represents the base class for the ComPtrRef class.
DontUseNewUseMake Class	Prevents using operator `new` in `RuntimeClass`. Consequently, you must use the Make function instead.
EventTargetArray Class	Represents an array of event handlers.
MakeAllocator Class	Allocates memory for an activatable class, with or without weak reference support.
ModuleBase Class	Represents the base class of the Module classes.
RemoveIUnknown Class	Makes a type that is equivalent to an `IUnknown`-based type, but has non-virtual `QueryInterface`, `AddRef`, and `Release` methods.
WeakReference Class	Represents a weak reference that can be used with the Windows Runtime or classic COM. A weak reference represents an object that might or might not be accessible.

Structures

Name	Description
ArgTraits Structure	Declares a specified delegate interface and an anonymous member function that has a specified number of parameters.
ArgTraitsHelper Structure	Helps define common characteristics of delegate arguments.
BoolStruct Structure	Defines whether a `ComPtr` is managing the object lifetime of an interface. `BoolStruct` is used internally by the BoolType() operator.
CreatorMap Structure	Contains information about how to initialize, register, and unregister objects.
DerefHelper Structure	Represent a dereferenced pointer to the `T*` template parameter.
EnableIf Structure	Defines a data member of the type specified by the second template parameter if the first template parameter evaluates to `true`.
FactoryCache Structure	Contains the location of a class factory and a value that identifies a registered Windows Runtime or COM class object.
ImplementsBase Structure	Used to validate template parameter types in Implements Structure.
ImplementsHelper Structure	Helps implement the Implements structure.
InterfaceList Structure	Used to create a recursive list of interfaces.
InterfaceListHelper Structure	Builds an `InterfaceList` type by recursively applying the specified template parameter arguments.
InterfaceTraits Structure	Implements common characteristics of an interface.
InvokeHelper Structure	Provides an implementation of the `Invoke()` method based on the specified number and type of arguments.
IsBaseOfStrict Structure	Tests whether one type is the base of another.
IsSame Structure	Tests whether one specified type is the same as another specified type.
Nil Structure	Used to indicate an unspecified, optional template parameter.
RemoveReference Structure	Strips the reference or rvalue-reference trait from the specified class template parameter.
RuntimeClassBase Structure	Used to detect `RuntimeClass` in the Make function.
RuntimeClassBaseT Structure	Provides helper methods for `QueryInterface` operations and getting interface IDs.
VerifyInheritanceHelper Structure	Tests whether one interface is derived from another interface.
VerifyInterfaceHelper Structure	Verifies that the interface specified by the template parameter meets certain requirements.

Enumerations

Name	Description
AsyncStatusInternal Enumeration	Specifies a mapping between internal enumerations for the state of asynchronous operations and the `Windows::Foundation::AsyncStatus` enumeration.

Functions

Name	Description
ActivationFactoryCallback Function	Gets the activation factory for the specified activation ID.
Move Function	Moves the specified argument from one location to another.
RaiseException Function	Raises an exception in the calling thread.
Swap Function (WRL)	Exchanges the values of the two specified arguments.
TerminateMap Function	Shuts down the class factories in the specified module.
