我正在用 C# 实现状态机，但遇到了问题。我有一个事件日志，包含事件和时间戳。在处理这个时，我得到以下格式的输出：转换的时间戳，状态转换到，状态时间
我在这里遇到的问题是，在我运行事件日志并找到有效的转换之前，我还不知道状态时间。在我的实现中，我使用一些函数来处理事件的触发，并返回一个元组，其中包含一个带有一些数据（转换时间和新状态）的字符串，但是因为我不知道这个状态的时间是多少我还不能正确地写它。在处理完一个事件集（启动此事件的多种方法、步进函数、运行到断点函数）之后，元组中的字符串被写入一个列表，当整个事件日志被处理时，该列表被写入一个文件。
不要过多地看元组的扩展使用，这是因为我正在测试一些东西，那部分仍然可以优化，我只是在寻找一些好主意来解决我在状态部分的时间问题。
触发一个事件的函数：
/// <summary>
/// Trigger an event in the event log on the state machine
/// </summary>
/// <param name="ev">Event to be triggered</param>
/// <param name="oldDate">Initial date</param>
/// <param name="oldMs">Initial milliseconds</param>
/// <returns>Tuple containing output string for event log, new date and new milliseconds belonging to the date</returns>
public Tuple<Tuple<string, string, string>, DateTime, int> TriggerEvent(Event ev, DateTime oldDate, int oldMs)
{
string outputString;
int newMs = oldMs;
DateTime newDate = oldDate;
Tuple<string, string, string> outPut;
if (this.Fire(ev.Trigger))
{
int outputMs = ev.Milliseconds - oldMs;
TimeSpan outputTs = ev.Timestamp - oldDate;
if (outputMs < 0)
{
outputMs = Math.Abs(outputMs);
outputTs = outputTs.Add(TimeSpan.FromSeconds(-1));
}
string firstPart = ev.Timestamp + "." + ev.Milliseconds.ToString();
string secondPart = this.fsm.State;
string thirdPart = outputTs + "." + outputMs.ToString().PadRight(6, '0');
outputString = firstPart + "," + secondPart;// +"," + thirdPart;
newDate = ev.Timestamp;
newMs = ev.Milliseconds;
this.activeState = this.GetStateByTag(this.fsm.State);
outPut = new Tuple<string, string, string>(firstPart, secondPart, thirdPart);
}
else
{
outputString = string.Empty;
outPut = new Tuple<string, string, string>(string.Empty, string.Empty, string.Empty);
}
this.lastEvent = ev;
return new Tuple<Tuple<string, string, string>, DateTime, int>(outPut, newDate, newMs);
}
处理事件列表的函数：
/// <summary>
/// Process an event log
/// </summary>
/// <param name="list">Event list to process</param>
/// <returns>List containing the output for storage</returns>
public Tuple<List<string>, Event> ProcessEventSet(List<Event> list)
{
List<string> tmpObj = new List<string>();
Tuple<string, string, string> outPut;
if (this.initialDate == DateTime.MinValue)
{
this.initialDate = list.First().Timestamp;
this.initialMs = list.First().Milliseconds;
}
foreach (Event ev in list)
{
Tuple<Tuple<string, string, string>, DateTime, int> newData = this.TriggerEvent(ev, this.initialDate, this.initialMs);
outPut = newData.Item1;
if (!string.IsNullOrEmpty(newData.Item1.Item1))
{
string output;
if (outPut.Item3 == "00:00:00.000000")
{
output = outPut.Item1 + "," + outPut.Item2;
}
else
{
output = outPut.Item1 + "," + outPut.Item2 + "," + outPut.Item3;
}
tmpObj.Add(output);
this.initialDate = newData.Item2;
this.initialMs = newData.Item3;
}
}
return new Tuple<List<string>, Event>(tmpObj, list.Last());
}
我得到的输出：
