Detailed Description

Manager for RAuxStore objects.

This class is used when connecting RAuxStore objects to the input ntuple as the auxiliary store of a DV container.

RAuxManager() [2/2]

xAOD::RAuxManager::RAuxManager

(

const RAuxManager &

       : m_store( parent.m_store ), m_storePtr( parent.m_storePtr ) {}

Member Function Documentation

create()

Bool_t xAOD::RAuxManager::create ( )

overridevirtual

Create the object for the current event.

There is no need for a default object.

Implements xAOD::TVirtualManager.

Definition at line 65 of file RAuxManager.cxx.

                              {
 
      return kTRUE;
   }

getConstStore()

const SG::IConstAuxStore * xAOD::RAuxManager::getConstStore

(

)

const

Get a convenience pointer to the managed object.

Definition at line 99 of file RAuxManager.cxx.

                                                            {
 
      return m_storePtr;
   }

getEntry()

Int_t xAOD::RAuxManager::getEntry ( ::Int_t  getall = 0 )

overridevirtual

Function for updating the object in memory if needed.

Implements xAOD::TVirtualManager.

Definition at line 38 of file RAuxManager.cxx.

                                             {
 
      return m_storePtr->getEntry( getall );
   }

getStore()

RAuxStore * xAOD::RAuxManager::getStore

(

)

Get a type-specific pointer to the managed object.

Definition at line 94 of file RAuxManager.cxx.

                                    {
 
      return m_storePtr;
   }

isSet()

Bool_t xAOD::RAuxManager::isSet ( ) const

overridevirtual

Check if the object was set for the current event.

The state of a RAuxStore object is always "set".

So this interface unfortunately doesn't make much sense for this manager class...

Implements xAOD::TVirtualManager.

Definition at line 74 of file RAuxManager.cxx.

                                   {
 
      return kTRUE;
   }

object() [1/2]

const void * xAOD::RAuxManager::object ( ) const

overridevirtual

Function getting a const pointer to the object being handled.

Implements xAOD::TVirtualManager.

Definition at line 43 of file RAuxManager.cxx.

                                         {
 
      return m_storePtr;
   }

object() [2/2]

void * xAOD::RAuxManager::object ( )

overridevirtual

Function getting a pointer to the object being handled.

Implements xAOD::TVirtualManager.

Definition at line 48 of file RAuxManager.cxx.

                             {
 
      return m_storePtr;
   }

operator=()

RAuxManager & xAOD::RAuxManager::operator=

(

const RAuxManager &

rhs

)

Assignment operator.

Definition at line 24 of file RAuxManager.cxx.

                                                               {
 
      // Check if anything needs to be done:
      if( this == &rhs ) {
         return *this;
      }
 
      // Do the assignment:
      m_store = rhs.m_store;
      m_storePtr = rhs.m_storePtr;
 
      return *this;
   }

reset()

void xAOD::RAuxManager::reset ( )

overridevirtual

Reset the object at the end of processing of an event.

Resetting an auxiliary store needs to be done in a smart way.

Container stores need to be emptied, while object stores don't need to be touched.

Implements xAOD::TVirtualManager.

Definition at line 83 of file RAuxManager.cxx.

                           {
 
      // Clear the store if it's a container store:
      if( m_storePtr->structMode() == RAuxStore::kContainerStore ) {
         m_storePtr->resize( 0 );
         m_storePtr->reset();
      }
 
      return;
   }

setObject()

void xAOD::RAuxManager::setObject ( void *  obj )

overridevirtual

Function replacing the object being handled.

Implements xAOD::TVirtualManager.

Definition at line 53 of file RAuxManager.cxx.

                                          {
 
      if( m_store.get() ) {
         m_store.reset( reinterpret_cast< RAuxStore* >( ptr ) );
      }
      m_storePtr = reinterpret_cast< RAuxStore* >( ptr );
 
      return;
   }
