Detailed Description

template<class T>
class SG::PackedContainer< T >

Container to hold aux data to be stored in a packed form.

This class acts as a std::vector<T> (in fact, it derives from that type). However, we set up a special ROOT streamer for this type so that when it is saved, it is written in a packed format. The details of the packing are given by the PackedParameters (which see) instance that we hold.

User code should generally not interact with this class directly.

PackedContainer may be used as a static auxiliary variable by using it instead of the corresponding vector class in the auxiliary store class. Packing parameters may then be set by calling setOption from the constructor for the aux store object.

For dynamic auxiliary variables, the stored vector is automatically converted to a PackedContainer when setOption is called for the variable.
