Classes

class  ROOT::VecOps::RVec< T >
 A "std::vector"-like collection of values implementing handy operation to analyse them. More...
 
class  ROOT::Detail::VecOps::RVecImpl< T >
 This class consists of common code factored out of the SmallVector class to reduce code duplication based on the SmallVector 'N' template parameter. More...
 
struct  ROOT::Internal::VecOps::RVecInlineStorageSize< T >
 The size of the inline storage of an RVec. More...
 
class  ROOT::VecOps::RVecN< T, N >
 
struct  ROOT::Internal::VecOps::SmallVectorAlignmentAndSize< T >
 Used to figure out the offset of the first element of an RVec. More...
 
class  ROOT::Internal::VecOps::SmallVectorBase
 This is all the stuff common to all SmallVectors. More...
 
struct  ROOT::Internal::VecOps::SmallVectorStorage< T, N >
 Storage for the SmallVector elements. More...
 
struct  ROOT::Internal::VecOps::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  ROOT::Internal::VecOps::SmallVectorTemplateBase< T, bool >
 SmallVectorTemplateBase<TriviallyCopyable = false> - This is where we put method implementations that are designed to work with non-trivial T's. More...
 
class  ROOT::Internal::VecOps::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  ROOT::Internal::VecOps::SmallVectorTemplateCommon< T >
 This is the part of SmallVectorTemplateBase which does not depend on whether the type T is a POD. More...
 

Namespaces

namespace  ROOT
 tbb::task_arena is an alias of tbb::interface7::task_arena, which doesn't allow to forward declare tbb::task_arena without forward declaring tbb::interface7
 
namespace  ROOT::Detail
 Special implementation of ROOT::RRangeCast for TCollection, including a check that the cast target type inherits from TObject and a new constructor that takes the TCollection by pointer.
