Example 6 with BucketCalculator

use of com.infiniteautomation.mango.quantize.BucketCalculator in project ma-core-public by infiniteautomation.

the class AggregateDao method aggregate.

/**
 * Aggregate a stream of raw point values into aggregate statistics. Mango statistics rely on knowing the initial
 * value of the point before the "from" time, you must include an initial start value in the stream (if one exists).
 * The timestamp of this start value should be less than the "from" time.
 *
 * @param point data point
 * @param from from time (inclusive)
 * @param to to time (exclusive)
 * @param pointValues stream of point values, must include a start value (at time < from) for accurate statistics
 * @param aggregationPeriod aggregation period (bucket/window size)
 * @return stream of aggregates
