ROOT::Internal::VecOps Namespace Reference

Classes
struct	IsRVec
struct	IsRVec< ROOT::VecOps::RVec< T > >
struct	RVecInlineStorageSize
	The size of the inline storage of an RVec. More...
struct	SmallVectorAlignmentAndSize
	Used to figure out the offset of the first element of an RVec. More...
class	SmallVectorBase
	This is all the stuff common to all SmallVectors. More...
struct	SmallVectorStorage
	Storage for the SmallVector elements. More...
struct	SmallVectorStorage< T, 0 >
	We need the storage to be properly aligned even for small-size of 0 so that the pointer math in SmallVectorTemplateCommon::getFirstEl() is well-defined. More...
class	SmallVectorTemplateBase
	SmallVectorTemplateBase<TriviallyCopyable = false> - This is where we put method implementations that are designed to work with non-trivial T's. More...
class	SmallVectorTemplateBase< T, true >
	SmallVectorTemplateBase<TriviallyCopyable = true> - This is where we put method implementations that are designed to work with trivially copyable T's. More...
class	SmallVectorTemplateCommon
	This is the part of SmallVectorTemplateBase which does not depend on whether the type T is a POD. More...

constexpr bool ROOT::Internal::VecOps::All ( const bool *  vals, std::size_t  size  )

constexpr

GetVectorsSize()

template<typename... T>

std::size_t ROOT::Internal::VecOps::GetVectorsSize	(	const std::string &	id,
		const RVec< T > &...	vs
	)

		std::index_sequence< Is... >
	)		-> decltype(MapImpl(std::get<std::tuple_size<Tuple_t>::value - 1>(t), std::get<Is>(t)...))

MapImpl()

template<typename F , typename... RVecs>

auto ROOT::Internal::VecOps::MapImpl	(	F &&	f,

NextPowerOf2()

uint64_t ROOT::Internal::VecOps::NextPowerOf2 ( uint64_t  A )

inline

Return the next power of two (in 64-bits) that is strictly greater than A.

Return zero on overflow.

Definition at line 126 of file RVec.hxx.

ResetView()

template<typename T >

void ROOT::Internal::VecOps::ResetView	(	RVec< T > &	v,
		T *	addr,
		std::size_t	sz
	)

An unsafe function to reset the buffer for which this RVec is acting as a view.

Note

This is a low-level method that must be called on RVecs that are already non-owning:

• it does not put the RVec in "non-owning mode" (fCapacity == -1)
• it does not free any owned buffer

Definition at line 546 of file RVec.hxx.

		ForwardIt	last
