| Public Member Functions inherited from ROOT::Internal::VecOps::SmallVectorBase | |
| size_t | capacity () const noexcept |
| bool | empty () const |
| void | set_size (size_t N) |
Set the array size to N, which the current array must have enough capacity for. | |
| size_t | size () const |
Protected Member Functions | |
| SmallVectorTemplateCommon (size_t Size) | |
| void | grow_pod (size_t MinSize, size_t TSize) |
| bool | isSmall () const |
| Return true if this is a smallvector which has not had dynamic memory allocated for it. | |
| void | resetToSmall () |
| Put this vector in a state of being small. | |
| Protected Member Functions inherited from ROOT::Internal::VecOps::SmallVectorBase | |
| SmallVectorBase ()=delete | |
| SmallVectorBase (void *FirstEl, size_t TotalCapacity) | |
| void | grow_pod (void *FirstEl, size_t MinSize, size_t TSize) |
| This is an implementation of the grow() method which only works on POD-like data types and is out of line to reduce code duplication. | |
| bool | Owns () const |
| If false, the RVec is in "memory adoption" mode, i.e. it is acting as a view on a memory buffer it does not own. | |
Private Types | |
| using | Base = SmallVectorBase |
Private Member Functions | |
| void * | getFirstEl () const |
| Find the address of the first element. | |
Additional Inherited Members | |
| Static Protected Member Functions inherited from ROOT::Internal::VecOps::SmallVectorBase | |
| static void | report_at_maximum_capacity () |
| Report that this vector is already at maximum capacity. | |
| static void | report_size_overflow (size_t MinSize) |
| Report that MinSize doesn't fit into this vector's size type. | |
| static constexpr size_t | SizeTypeMax () |
| The maximum value of the Size_T used. | |
| Protected Attributes inherited from ROOT::Internal::VecOps::SmallVectorBase | |
| void * | fBeginX |
| Size_T | fCapacity |
| Always >= -1. fCapacity == -1 indicates the RVec is in "memory adoption" mode. | |
| Size_T | fSize = 0 |
| Always >= 0. | |

Find the address of the first element.
For this pointer math to be valid with small-size of 0 for T with lots of alignment, it's important that SmallVectorStorage is properly-aligned even for small-size of 0.
