isRegisteredType()

bool xAOD::details::isRegisteredType

(

SG::auxid_t

auxid

)

Check if the auxiliary variable has a registered type.

This function is used to test if a given auxiliary variable is known in the registry with a proper type.

Returns

true if the full type of the auxiliary property is known, false otherwise

                                       {
 
  // Cache some data:
  static SG::AuxTypeRegistry& registry ATLAS_THREAD_SAFE =
      SG::AuxTypeRegistry::instance();
  static const SG::auxid_t sauxid =
      registry.getAuxID<SG::AuxTypePlaceholder>("AuxTypePlaceholder");
  static const std::type_info* const sti = registry.getVecType(sauxid);
 
  // Check if the types match:
  return (*sti != *(registry.getVecType(auxid)));

lookupVectorType()

TClass * xAOD::details::lookupVectorType

(

TClass &

cl

)

Internal function used by xAOD::TAuxStore and xAOD::RAuxStore.

It looks for a typedef called vector_type on the type given to it.

Parameters

cl	The type that should be searched for the typedefed type

Returns

The dictionary for the vector type, if it exists

  if (typ) {
    return TClass::GetClass(typ->GetFullTypeName());
  }
