smash::OutputInterface Class Reference

#include <outputinterface.h>

Abstraction of generic output.

Any output should inherit this class. It provides virtual methods that will be called at predefined moments: 1) At event start and event end: at_eventstart, at_eventend 2) After every fixed time period: at_intermediate_time, thermodynamics_output 3) At each interaction: at_interaction
