Detailed Description

template<class DCP>
class famouso::mw::afp::defrag::OutOfOrderEventDataReconstructor< DCP >

Policy: Reconstruct event data from fragments that may arrive out of order. Does not support forward error correction.

Using this policy automatically selects NoFECHeaderSupport as FEC header policy.

Alternative policies: InOrderEventDataReconstructor, FECEventDataReconstructor
