Detailed Description

template<class TYPE>
class ObjectVector< TYPE >

ObjectVector is one of the basic Gaudi container classes capable of being registered in Data Stores.

It is based on Standard Library (STL) std::vector (see STL Programmer's Guide) ObjectVector has all functions of the std::vector interface, and in addition a number of Gaudi specific functions.

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.
