Modifier and Type	Class	Description
static class	Utils.Granularity	Standard supported aggregation Granularities.
static class	Utils.HistogramKey	Uniquely identifies a time-series - time-interval pair.
static class	Utils.HistogramKeyMarshaller	(For now, a rather trivial) encoding of Utils.HistogramKey the form short length and bytes Consider using chronicle-values or making this stateful with a local byte[] / Stringbuffers to be a little more efficient about encodings.

makeKey

public static Utils.HistogramKey makeKey(wavefront.report.ReportPoint point,
                                         Utils.Granularity granularity)

Generates a Utils.HistogramKey according a prototype ReportPoint and Utils.Granularity.

pointFromKeyAndDigest

public static wavefront.report.ReportPoint pointFromKeyAndDigest(Utils.HistogramKey histogramKey,
                                                                 AgentDigest agentDigest)

Creates a ReportPoint from a Utils.HistogramKey - AgentDigest pair

Parameters:

histogramKey - the key, defining metric, source, annotations, duration and start-time

agentDigest - the digest defining the centroids

Returns:

the corresponding point
