Detailed Description

template<typename FuncType>
class uLang::TUniqueFunction< FuncType >

TUniqueFunction<FuncType>

See the class definition for intended usage.

TUniqueFunction<FuncType>

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

Example:

TUniquePtr<FThing> Thing = MakeUnique<FThing>();

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

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

operator bool()

template<typename FuncType >

ULANG_FORCEINLINE uLang::TUniqueFunction< FuncType >::operator bool ( ) const

inlineexplicit

Tests if the TUniqueFunction is callable.

operator=() [1/2]
