Detailed Description

Base class for importing objects to the database.

Note that the object is NOT parked at DBStore, but allocated internally.

Definition at line 23 of file DBImportBase.h.

Constructor & Destructor Documentation

DBImportBase() [1/2]

DBImportBase ( const std::string &  name )

inlineexplicit

Constructor.

Parameters

name	Name under which the object will be stored in the database

Definition at line 30 of file DBImportBase.h.

: m_name(name) {}

~DBImportBase()

~DBImportBase ( )

virtual

Destructor.

Definition at line 76 of file DBImportBase.cc.

{
  for (auto& object : m_objects) delete object;
}

DBImportBase() [2/2]

DBImportBase ( const DBImportBase &  )

private

Hidden copy constructor.

To prevent making copies, since the class contains pointer to allocated memory.

Parameters

iov	interval of validity

Definition at line 114 of file DBImportBase.h.

    {
      if (m_objects.empty()) return false;
      IntraRun intraRun(m_objects[0], false); // IntraRun must not own the objects

iov	interval of validity

Definition at line 71 of file DBImportBase.cc.

{
  return Database::Instance().storeData(m_name, intraRun, iov);
