Detailed Description

Manager for TAuxStore objects.

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

Member Function Documentation

◆ create()

Bool_t xAOD::TAuxManager::create ( )
overridevirtual

Create the object for the current event.

There is no need for a default object.

Implements xAOD::TVirtualManager.

Definition at line 70 of file TAuxManager.cxx.

70  {
71 
72  return kTRUE;
73  }

◆ getConstStore()

const SG::IConstAuxStore * xAOD::TAuxManager::getConstStore ( ) const

Get a convenience pointer to the managed object.

Definition at line 104 of file TAuxManager.cxx.

104  {
105 
106  return m_storePtr;
107  }

◆ getEntry()

Int_t xAOD::TAuxManager::getEntry ( ::Int_t  getall = 0)
overridevirtual

Function for updating the object in memory if needed.

Implements xAOD::TVirtualManager.

Definition at line 43 of file TAuxManager.cxx.

43  {
44 
45  return m_storePtr->getEntry( getall );
46  }

◆ getStore()

TAuxStore * xAOD::TAuxManager::getStore ( )

Get a type-specific pointer to the managed object.

Definition at line 99 of file TAuxManager.cxx.

99  {
100 
101  return m_storePtr;
102  }

◆ isSet()

Bool_t xAOD::TAuxManager::isSet ( ) const
overridevirtual

Check if the object was set for the current event.

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

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

Implements xAOD::TVirtualManager.

Definition at line 79 of file TAuxManager.cxx.

79  {
80 
81  return kTRUE;
82  }

◆ object() [1/2]

const void * xAOD::TAuxManager::object ( ) const
overridevirtual

Function getting a const pointer to the object being handled.

Implements xAOD::TVirtualManager.

Definition at line 48 of file TAuxManager.cxx.

48  {
49 
50  return m_storePtr;
51  }

◆ object() [2/2]

void * xAOD::TAuxManager::object ( )
overridevirtual

Function getting a pointer to the object being handled.

Implements xAOD::TVirtualManager.

Definition at line 53 of file TAuxManager.cxx.

53  {
54 
55  return m_storePtr;
56  }

◆ operator=()

TAuxManager & xAOD::TAuxManager::operator= ( const TAuxManager rhs)

Assignment operator.

Definition at line 29 of file TAuxManager.cxx.

29  {
30 
31  // Check if anything needs to be done:
32  if( this == &rhs ) {
33  return *this;
34  }
35 
36  // Do the assignment:
37  m_store = rhs.m_store;
38  m_storePtr = rhs.m_storePtr;
39 
40  return *this;
41  }

◆ reset()

void xAOD::TAuxManager::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 88 of file TAuxManager.cxx.

88  {
89 
90  // Clear the store if it's a container store:
92  m_storePtr->resize( 0 );
93  m_storePtr->reset();
94  }
95 
96  return;
97  }

◆ setObject()

void xAOD::TAuxManager::setObject ( void *  obj)
overridevirtual

Function replacing the object being handled.

Implements xAOD::TVirtualManager.

Definition at line 58 of file TAuxManager.cxx.

58  {
59 
60  if( m_store.get() ) {
61  m_store.reset( reinterpret_cast< TAuxStore* >( ptr ) );
62  }
63  m_storePtr = reinterpret_cast< TAuxStore* >( ptr );
64 
65  return;
66  }
