TUniqueFunction

See the class definition for intended usage.

TUniqueFunction

Used like TFunction above, but is move-only. This allows non-copyable functors to be bound to it.

Example:

TUniquePtr Thing = MakeUnique();

TFunction CopyableFunc = Thing = Move(Thing){ Thing->DoSomething(); }; // error - lambda is not copyable TUniqueFunction MovableFunc = Thing = Move(Thing){ Thing->DoSomething(); }; // ok

void Foo(TUniqueFunction Func); Foo(MovableFunc); // error - TUniqueFunction is not copyable Foo(Move(MovableFunc)); // ok

	Type	Name	Description
		TUniqueFunction ( NullPtrType )	Default constructor.
		TUniqueFunction ( FunctorType&& InFunc )	Constructor which binds a TFunction to any function object.
		TUniqueFunction ( TFunction< FuncType >&& Other )	Constructor which takes ownership of a TFunction's functor.
		TUniqueFunction ( const TFunction< FuncType >& Other )	Constructor which takes ownership of a TFunction's functor.
		TUniqueFunction ( TUniqueFunction&& )
		TUniqueFunction ( const TUniqueFunction& Other )

	Type	Name	Description
		~TUniqueFunction ()

	Type	Name	Description
	void	Reset ()	Removes any bound callable from the TFunction, restoring it to the default 'empty' state.

Type	Name	Description
ULANG_FORCEINLINE	operator bool ()	Tests if the TUniqueFunction is callable.
TUniqueFunction &	operator= ( TUniqueFunction&& Other )	Copy/move assignment operator.
