Member Typedef Documentation

DataObjectVec

typedef std::vector<DataObject*> AthenaOutputStreamTool::DataObjectVec

Stream out a vector of objects Must convert to DataObject, e.g.

#include "AthenaKernel/StorableConversions.h" T* obj = xxx; DataObject* dataObject = SG::asStorable(obj);

Definition at line 76 of file AthenaOutputStreamTool.h.

TypeKeyPair

typedef std::pair<std::string, std::string> AthenaOutputStreamTool::TypeKeyPair

Stream out objects.

Provide vector of typeName/key pairs. If key is empty, assumes only one object and this will fail if there is more than one
