示例1: FileSegmenter
public FileSegmenter(IObservable<FileNotification> notifications,
int initialTail= 100000,
int segmentSize=25000000)
{
if (notifications == null) throw new ArgumentNullException(nameof(notifications));
_initialTail = initialTail;
_segmentSize = segmentSize;
//TODO: Re-segment as file grows + account for rollover
Segments = notifications
//.notifications()
.Scan((FileSegmentCollection) null, (previous, current) =>
{
if (previous == null || previous.FileLength == 0)
{
_info =(FileInfo) current;
var segments = LoadSegments().ToArray();
return new FileSegmentCollection(_info, segments, current.Size);
}
var newLength = _info.Length;
if (newLength < previous.FileLength)
{
var sizeDiff = newLength - previous.FileLength;
var segments = LoadSegments().ToArray();
return new FileSegmentCollection(_info, segments, sizeDiff);
}
return new FileSegmentCollection(newLength, previous);
}).Replay(1).RefCount();
}示例2: Filter

queue.Enqueue(f);
if (queue.Count > bufferSize)
queue.Dequeue();
return queue;
}).Select(q => q.Average());
}示例3: computeTeamBallPossessionFullGame
//this function computes the TeamBall Possession data for the entire game

.Scan<double, double>(0,
(acc, currentValue) =>
{
return agg.Aggregate(currentValue);
}).Subscribe((state) => act(state, Constants.REDIS_MVA_ROOM_PREFIX + symbolId));
