virtualinherited

Type-safe wrapper for get.

Parameters

Return the object as a pointer to the ti type. Return 0 if the get fails or if the pointer can't be converted.

getUntyped()

virtual const void * D3PD::SGCollectionGetterTool< CaloCalibrationHitContainer >::getUntyped ( bool allowMissing = false )

virtualinherited

Return the target object.

Parameters

allowMissing

If true, then we should not generate errors if the requested object is missing.

Reimplemented from D3PD::SGGetterImpl.

initialize()

virtual StatusCode D3PD::SGCollectionGetterTool< CaloCalibrationHitContainer >::initialize ( )

virtualinherited

Standard Gaudi initialize method.

initializeImpl()

StatusCode D3PD::SGGetterImpl::initializeImpl ( )

protectedinherited

Initialize this mixin class.

Call this from initialize.

{
  CHECK( m_clidsvc.retrieve() );
 
  CHECK( nameToCLID (m_typename, m_clid, this->name(), m_clidsvc) );

  return StatusCode::SUCCESS;
}

nextTypeinfo()

const void * D3PD::CollectionGetterToolImpl::nextTypeinfo ( const std::type_info & ti )

inherited

Return the next object cast to a different pointer type.

Return the next element from the collection as a pointer to the ti type. Return 0 if the pointer can't be converted or at the end of the iteration.

Definition at line 68 of file CollectionGetterToolImpl.cxx.

{
  // Configure the converter.
  if (!this->m_converter.isValid() ||
      this->m_converter.dstTypeinfo() != ti)
  {
    if (this->configureElementTypeinfo(ti).isFailure())
      return 0;
  }
 
  // Get the next object.  If the conversion fails, loop until we get
  // a good one.
  while (true) {
    const void* p = this->nextUntyped();
    if (!p) return 0;
    const void* pconv = this->m_converter.convertUntyped (p);

    REPORT_MESSAGE (MSG::WARNING)
      << "Pointer conversion from " << m_converter.srcName() << " to "

  }
}

nextUntyped()

virtual const void * D3PD::CollectionGetterTool< CaloCalibrationHitContainer >::nextUntyped ( )

virtualinherited

Return a pointer to the next element in the collection.

Return 0 when the collection has been exhausted.

releaseElementTypeinfo()

void D3PD::CollectionGetterToolImpl::releaseElementTypeinfo ( const void * p, const std::type_info & ti )

inherited

Release an element retrieved from the getter.

Parameters

p	The element to release.
ti	The type of p.

Call this when you are done with the element returned by nextUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

Definition at line 104 of file CollectionGetterToolImpl.cxx.

{
  if (!p)
    return;
 
  // Configure the converter if needed.
  if (!this->m_backConverter.isValid() ||
      this->m_backConverter.srcTypeinfo() != ti)
  {
    if (this->m_backConverter.init (ti, this->typeinfo()).isFailure()) {
      REPORT_MESSAGE (MSG::WARNING)
        << "Can't configure pointer conversion from "
        << System::typeinfoName (ti) << " to "

releaseObject() [1/2]

virtual void D3PD::CollectionGetterTool< CaloCalibrationHitContainer >::releaseObject ( const CaloCalibrationHitContainer * p )

virtualinherited

Release an object retrieved from the getter.

Parameters

p	The object to release.

Call this when you are done with the object returned by get(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

releaseObject() [2/2]

template<class T>

void D3PD::IObjGetterTool::releaseObject ( const T * p )

inherited

Type-safe wrapper for releaseObjectUntyped.

Parameters

p	The object to release.

Call this when you are done with the object returned by get(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

This is implemented in terms of releaseObjectTypeinfo().

releaseObjectTypeinfo()

void D3PD::IObjGetterTool::releaseObjectTypeinfo ( const void * p, const std::type_info & ti )

inherited

Release an object retrieved from the getter.

Parameters

p	The object to release.
ti	The type of p.

Call this when you are done with the object returned by getUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

releaseObjectUntyped() [1/2]

virtual void D3PD::CollectionGetterTool< CaloCalibrationHitContainer >::releaseObjectUntyped ( const void * p )

virtualinherited

Release an object retrieved from the getter.

Parameters

p	The object to release.

Call this when you are done with the object returned by getUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

releaseObjectUntyped() [2/2]

virtual void D3PD::IObjGetterTool::releaseObjectUntyped ( const void * p )

virtualinherited

Release an object retrieved from the getter.

Parameters

p	The object to release.

Call this when you are done with the object returned by getUntyped(). The default implementation is a no-op, but if the getter dynamically allocated the object which it returned, this gives it a chance to free it.

reset()

virtual StatusCode D3PD::CollectionGetterTool< CaloCalibrationHitContainer >::reset ( bool allowMissing = false )

virtualinherited

Reset the iteration to the start of the collection.

Parameters

allowMissing

If true, then we should not generate errors if the requested object is missing.

Return failure if the container cannot be retrieved.

sizeHint()

virtual size_t D3PD::CollectionGetterTool< CaloCalibrationHitContainer >::sizeHint ( bool allowMissing = false )

virtualinherited

Return an estimate of the number of elements in the iteration.

Parameters

allowMissing

If true, then we should not generate errors if the requested object is missing.

This can be used to pre-allocate memory. (It's possible that this isn't known in advance of iterating over the entire collection, for example if a selection is being applied, so this is only a hint.)

typeinfo()

virtual const std::type_info & D3PD::SGCollectionGetterTool< CaloCalibrationHitContainer >::typeinfo ( ) const

virtualinherited

Return the type of object retrieved by this tool.

Reimplemented from D3PD::SGGetterImpl.
