Detailed Description

ObjectList is one of the basic Gaudi container classes capable of being registered in Data Stores. It is based on Standard Library (STL) std::list (see STL Programmer's Guide) ObjectList has all functions of the std::list interface,

Each object is allowed to belong into a single container only. After inserting the object into the container, it takes over all responsibilities for the object. E.g. erasing the object from its container causes removing the object's pointer from the container and deleting the object itself.
