Detailed Description

template<typename T>
struct o2::framework::LifetimeHolder< T >

Helper to allow framework managed objecs to have a callback when they go out of scope. For example, this could be used to serialize a message into a buffer before the end of the timeframe, hence eliminating the need for the intermediate buffers.
