Detailed Description

Interface for objects taking part in direct ROOT I/O.

   This interface needs to be implemented by classes that serve as
   auxiliary containers that we want to use in our EDM directly.
   It allows the I/O infrastructure to give a store object to the
   object implementing this interface. At that point the object given
   to this interface will be the one doing the ROOT I/O for the
   "dynamic" auxiliary variables.

   Currently there's a single implementation of this,
   "xAODCore/AuxContainerBase.h", but we may want to have other
   implementations later on as well.

Member Enumeration Documentation

AuxStoreType

enum SG::IAuxStoreHolder::AuxStoreType

Type of the auxiliary store.

In the xAOD EDM we use auxiliary store objects in some cases to describe a single object, and in most cases to describe a container of objects. This enumeration declares which type the object implementing this interface is.

Enumerator
AST_ObjectStore	The store describes a single object.
AST_ContainerStore	The store describes a container.

                        {
         AST_ObjectStore    = 0, 
         AST_ContainerStore = 1  
      };

Member Function Documentation

getStore() [1/2]

virtual const IAuxStore* SG::IAuxStoreHolder::getStore ( ) const

pure virtual

Implemented in xAOD::ShallowAuxContainer, xAOD::AuxContainerBase, xAOD::AuxInfoBase, and APRTest::AuxStore.

getStore() [2/2]

virtual IAuxStore* SG::IAuxStoreHolder::getStore ( )

pure virtual

Return the pointer to the store object currently in use.

There's not much use case for this function yet, but it makes the interface complete at least.

Implemented in xAOD::ShallowAuxContainer, xAOD::AuxContainerBase, xAOD::AuxInfoBase, and APRTest::AuxStore.

getStoreType()

virtual AuxStoreType SG::IAuxStoreHolder::getStoreType ( ) const

pure virtual

Return the type of the store object.

See also

AuxStoreType

Implemented in xAOD::ShallowAuxContainer, xAOD::AuxContainerBase, xAOD::AuxInfoBase, APRTest::AuxStore, and xAOD::ShallowAuxInfo.

setStore()

virtual void SG::IAuxStoreHolder::setStore ( IAuxStore *  store )

pure virtual

Give an auxiliary store object to the holder object.

The purpose of this function is to give an alternate store object to this object instead of the one it uses normally.

Parameters

store

Pointer to an object implementing direct ROOT I/O

Implemented in xAOD::ShallowAuxContainer, xAOD::AuxContainerBase, and xAOD::AuxInfoBase.
