Method Detail

satisfy

boolean satisfy(Statistics statistics)

To examine whether the statistics is satisfied with the filter.

Parameters:

statistics - statistics with min time, max time, min value, max value.

satisfy

boolean satisfy(long time,
                Object value)

To examine whether the single point(with time and value) is satisfied with the filter.

Parameters:

time - single point time

value - single point value

satisfyStartEndTime

boolean satisfyStartEndTime(long startTime,
                            long endTime)

To examine whether the min time and max time are satisfied with the filter.

Parameters:

startTime - start time of a page, series or device

endTime - end time of a page, series or device

containStartEndTime

boolean containStartEndTime(long startTime,
                            long endTime)
