@DependentInitialisation(value=ch.sahits.game.openpatrician.util.StartNewGameBean.class)
public class SeaFightService
extends Object

The sea fight service helps calculating the winner of a sea fight based on two sets of ships. The central method is calculateOutcome(INavigableVessel, INavigableVessel, SeaFightContext). There are helper methods explodeShipList to convert the IShips to the required List of ships. There are further helper methods to collect the ships lists again after the fight.
The only case the must be handled without the help of a helper method is if a single ship (not a group or convoy) of a player (AI or human) is attacked or defends and is victorious. This might result in a list of ships that should then all travel to the same destination as single ships.
