Public class TChooseClass Chooses between two different classes based on a boolean.  
Public struct TContainerTraits    
Public struct TContainerTraitsBase Traits for containers.  
Public struct TDecay Returns the decayed type of T, meaning it removes all references, qualifiers and applies array-to-pointer and function-to-pointer conversions.

Public struct TGuardValue Exception-safe guard around saving/restoring a value.  
Public struct TIsArithmetic Traits class which tests if a type is arithmetic.  
Public struct TIsBitwiseConstructible Tests if a type T is bitwise-constructible from a given argument type U.  
Public struct TIsConstructible Determines if T is constructible from a set of arguments.  
Public struct TIsContiguousContainer Traits class which tests if a type is a contiguous container.  
Public struct TIsEnum    
Public struct TIsIntegral Traits class which tests if a type is integral.  
Public struct TIsInvocable Traits class which tests if an instance of CallableType can be invoked with a list of the arguments of the types provided.  
Public struct TIsInvocableImpl    
Public struct TIsLValueReferenceType TIsLValueReferenceType  
Public struct TIsMemberPointer Traits class which tests if a type is a pointer to member (data member or member function).  
Public struct TIsPODType Traits class which tests if a type is POD.  
Public struct TIsPointer Traits class which tests if a type is a pointer.  
Public struct TIsReferenceType TIsReferenceType

Public struct TIsZeroConstructType TIsZeroConstructType  
Public struct TLess Binary predicate class for sorting elements in order.  
Public struct TNot Does a boolean NOT of the Value static members of the type.  
Public struct TOr Does a boolean OR of the ::Value static members of each type, but short-circuits if any Type::Value == true.  
Public struct TOrValue    
Public struct TPointerIsConvertibleFromTo Tests if a From* is convertible to a To*  
Public class TPointerIsConvertibleFromTo_TestBase    
Public class TPointerIsConvertibleFromTo_TestDerived    
Public class TPointerIsConvertibleFromTo_Unrelated    
Public struct TPointerIsStaticCastableFromTo    
Public struct TRemoveCV TRemoveCV will remove any const/volatile qualifiers from a type.  
Public struct TRemovePointer Removes one level of pointer from a type, e.g.:  
Public struct TRemoveReference TRemoveReference will remove any references from a type.  
Public class TReversePredicate Helper class to reverse a predicate. Performs Predicate(B, A)  
Public struct TTypeCompatibleBytes An untyped array of data with compile-time alignment and size derived from another type.  
Public struct TTypeTraits Traits for types.  
Public struct TTypeTraitsBase Helper for array traits.

Functions

  Type Name Description
Public function ULANG_FORCEINLINE constexpr T

uLang::AlignUp ( T Val,
uint64_t Alignment
)

 Aligns a value to the nearest higher multiple of 'Alignment', which must be a power of two.
Public function ULANG_FORCEINLINE T &&

uLang::ForwardArg ( typename TRemoveReference< T >::Type&& Obj
)

  
Public function ULANG_FORCEINLINE T &&

uLang::ForwardArg ( typename TRemoveReference< T >::Type& Obj
)

 ForwardArg will cast a reference to an rvalue reference. This is UE's equivalent of std::forward.
Public function ULANG_FORCEINLINE auto

uLang::Invoke ( ReturnType ObjType::* pdm,
CallableType&& Callable
)

  
Public function ULANG_FORCEINLINE auto

uLang::Invoke ( FuncType&& Func,
ArgTypes&&... Args
)

 Invokes a callable with a set of arguments.
Public function ULANG_FORCEINLINE auto

uLang::Invoke ( ReturnType(ObjType::*)(PMFArgTypes...) PtrMemFun,
CallableType&& Callable,
ArgTypes&&... Args
)

  
Public function ULANG_FORCEINLINETRemoveReference< T >::Type &&

uLang::Move ( T&& Obj
)

 Move will cast a reference to an rvalue reference.
Public function ULANG_FORCEINLINETRemoveReference< T >::Type &&

uLang::MoveIfPossible ( T&& Obj
)

 MoveIfPossible will cast a reference to an rvalue reference.
Public function T &&  
Public function ULANG_FORCEINLINE auto

uLang::Private::DereferenceIfNecessary ( CallableType&& Callable
)

  
Public function TEnableIf< TUseBitwiseSwap< T >::Value >::Type

uLang::Swap ( T& A,
T& B
)

 Swap two values. Assumes the types are trivially relocatable.
Public function TEnableIfTUseBitwiseSwap< T >::Value >::Type

uLang::Swap ( T& A,
T& B
)

  
Public function  

uLang::TGuard ( Function&&
)

  
Public function decltype(Container.GetData())

uLang::ULangGetData ( T&& Container
)

 Generically gets the data pointer of a contiguous container Named differently from GetData() in UnrealTemplate.h to avoid ambiguous overload resolution.
Public function T *

uLang::ULangGetData ( T(&) Container
)

  
Public function T *

uLang::ULangGetData ( std::initializer_list< T > List
)

  
Public function FirstIterator

)

  
Public function size_t

uLang::ULangGetNum ( T&& Container
)

 Generically gets the number of items in a contiguous container Named differently from GetNum() in UnrealTemplate.h to avoid ambiguous overload resolution.
Public function size_t

uLang::ULangGetNum ( T(&) Container
)

  
Public function int32_t

uLang::ULangGetNum ( const TRangeView< FirstIterator, LastIterator >& View
)
