Detailed Description

template<typename T>
class tervel::containers::wf::RingBuffer< T >::Value

RingBuffer value class, values stored in the class must extend it.

This class is necessary to provide the FIFO property. It adds a sequence identifier to each value stored. Using this identifier, we are apply generate FIFO valid sequential history from a concurrent history.
