Typedef Documentation

PersistentVectorRegister4Double

using PersistentVectorRegister4Double = VectorRegister4Double

PersistentVectorRegister4Float

using PersistentVectorRegister4Float = VectorRegister4Float

TPersistentVectorRegisterType

template<typename T >

using TPersistentVectorRegisterType = std::conditional_t<std::is_same_v<T, float>, PersistentVectorRegister4Float, std::conditional_t<std::is_same_v<T, double>, PersistentVectorRegister4Double, void> >

Alias for VectorRegister type to be used as member variables of structs, when alignment should not be over 16 bytes. 32-byte alignment requires large allocations in some allocators, which we want to avoid. See PersistentVectorRegister4Double for more details.

Usage example: TPersistentVectorRegisterType<float> MyFloatRegister; TPersistentVectorRegisterType<double> MyDoubleRegister;

TVectorRegisterType

template<typename T >

using TVectorRegisterType = typename UE::Math::VectorRegisterPrivate::TVectorRegisterTypeHelper<T>::Type
