Detailed Description

Interface providing I/O for a generic auxiliary store.

   In order to read/write the properties stored in a generic
   auxiliary store object, this interface needs to be used.
   It allows the infrastructure code to inspect the contents
   of the object, and access it in a way that allows the
   information to be passed to the persistency system.

Member Function Documentation

getDynamicAuxIDs()

virtual const SG::auxid_set_t& SG::IAuxStoreIO::getDynamicAuxIDs ( ) const

pure virtual

Get the list of all dynamically created variables.

Implemented in SG::AuxStoreInternal, xAOD::TAuxStore, xAOD::AuxContainerBase, xAOD::ShallowAuxContainer, xAOD::AuxInfoBase, and xAOD::RAuxStore.

getIOData()

virtual const void* SG::IAuxStoreIO::getIOData ( SG::auxid_t  auxid ) const

pure virtual

Return a pointer to the data to be stored for one aux data item.

Parameters

auxid

The identifier of the desired aux data item.

This will usually be a pointer to a std::vector; however, it may be something different for a standalone object.

Returns 0 and reports an error if the requested aux data item does not exist.

Implemented in SG::AuxStoreInternal, RootAuxDynStore, xAOD::TAuxStore, xAOD::AuxContainerBase, xAOD::ShallowAuxContainer, xAOD::AuxInfoBase, and xAOD::RAuxStore.

getIOType()

virtual const std::type_info* SG::IAuxStoreIO::getIOType ( SG::auxid_t  auxid ) const

pure virtual

Return the type of the data to be stored for one aux data item.

Parameters

auxid

The identifier of the desired aux data item.

For an aux data item of type T, this will usually be std::vector<T>. For standalone objects, however, it will usually be T; and std::vector<char> will be used instead of std::vector<bool>.

Returns 0 if the requested aux data item does not exist.

Implemented in SG::AuxStoreInternal, xAOD::TAuxStore, xAOD::AuxContainerBase, xAOD::ShallowAuxContainer, xAOD::AuxInfoBase, and xAOD::RAuxStore.

getSelectedAuxIDs()

virtual SG::auxid_set_t SG::IAuxStoreIO::getSelectedAuxIDs ( ) const

inlinevirtual

Get a list of dynamic variables that need to be written out.

Reimplemented in xAOD::TAuxStore, xAOD::AuxContainerBase, xAOD::ShallowAuxContainer, xAOD::AuxInfoBase, and xAOD::RAuxStore.

Definition at line 86 of file IAuxStoreIO.h.

                                                  {
     // default all are selected
     return getDynamicAuxIDs();
  }
