Class managing concrete persistent variables
This class is used internally by the "special" auxiliary store objects to manage the auxiliary variables handled by them. User code probably doesn't want to touch it directly...
| virtual const std::type_info* xAOD::AuxPersInfo< T >::objType | ( | ) | const [inline, virtual] |
Return the type of the complete object to be saved.
For example, if the object is a std::vector, then we return the type_info of the vector. But if we're holding a PackedContainer, then we return the type_info of the PackedContainer.
Can return null if the operation is not supported. In that case, I/O will use the type found from the variable registry.
Reimplemented from SG::IAuxTypeVector.
| virtual void xAOD::AuxPersInfo< T >::reserve | ( | size_t | sz | ) | [inline, virtual] |
Change the capacity of the vector.
| sz | The new vector capacity. |
Implements SG::IAuxTypeVector.
| virtual void xAOD::AuxPersInfo< T >::resize | ( | size_t | sz | ) | [inline, virtual] |
| virtual void xAOD::AuxPersInfo< T >::shift | ( | size_t | pos, | |
| ptrdiff_t | offs | |||
| ) | [inline, virtual] |
Shift the elements of the vector.
| pos | The starting index for the shift. | |
| offs | The (signed) amount of the shift. |
This operation shifts the elements in the vectors for all aux data items, to implement an insertion or deletion. offs may be either positive or negative.
If offs is positive, then the container is growing. The container size should be increased by offs, the element at pos moved to pos + offs, and similarly for following elements. The elements between pos and pos + offs should be default-initialized.
If offs is negative, then the container is shrinking. The element at pos should be moved to pos + offs, and similarly for following elements. The container should then be shrunk by -offs elements (running destructors as appropriate).
Implements SG::IAuxTypeVector.
