# TimingDistributionData

`data class TimingDistributionData` [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/service/glean/src/main/java/mozilla/components/service/glean/storages/TimingDistributionsStorageEngine.kt#L132)

This class represents the structure of a timing distribution according to the pipeline schema. It
is meant to help serialize and deserialize data to the correct format for transport and storage,
as well as including a helper function to calculate the bucket sizes.

### Parameters

`category` - of the metric

`name` - of the metric

`bucketCount` - total number of buckets

`range` - an array always containing 2 elements: the minimum and maximum bucket values

`histogramType` - the [HistogramType](../../mozilla.components.service.glean.metrics/-histogram-type/index.md) representing the bucket layout

`values` - a map containing the bucket index mapped to the accumulated count

`sum` - the accumulated sum of all the samples in the timing distribution

`timeUnit` - the base [TimeUnit](../../mozilla.components.service.glean.metrics/-time-unit/index.md) of the bucket values
