Method Summary

void	abort()
void	buildPlayField(java.lang.String positionID) later on make Engine and XiStratPanel extend s.th. and put that source code into 1 single place (or whatever design pattern (composition vs inheritance) might be used instead to avoid ugly copy/paste) clientCore calls this after loginAck by server does as well hashTables declaration and initialization
void	doMove(int from, int to) sync representation
void	doPass()
void	doPut(int to, int cont) dummy
void	doRemove(int loc, int cont) dummy
void	doUndo(int num)
int	evaluate(FigurData[] fastFigs, int atTurnOf) inside loop, we use an incremental procedure instead
void	handleNewGame(boolean ok, java.lang.String info) methods called by F4ClientCore, implemeting ClientUI
void	logout()
void	lose(java.lang.String winner)
int[]	multiEvaluate(FigurData[] fastFigs, int size)
void	run() for the moment we only do s.th. when it's our turn (no pondering, that is: no thinking on time of others so far)
void	setGameList(java.lang.String[] list, java.lang.String[] position) interface ClientUI
void	showErr(java.lang.String error)
void	showMsg(java.lang.String info)
void	waitForUserMove(boolean waitForMe)
void	waitForUserRemove(boolean wait)
void	waitForUserUndo(boolean undoForMe) after victory, engine is nice and makes undo of the last 2 elementar moves (plies)
