# TimespanMetricType

`data class TimespanMetricType : `[`CommonMetricData`](../-common-metric-data/index.md) [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/service/glean/src/main/java/mozilla/components/service/glean/metrics/TimespanMetricType.kt#L19)

This implements the developer facing API for recording timespans.

Instances of this class type are automatically generated by the parsers at build time,
allowing developers to record values that were previously registered in the metrics.yaml file.

The timespans API exposes the [start](start.md), [stopAndSum](stop-and-sum.md) and [cancel](cancel.md) methods.

### Properties

| Name | Summary |
|---|---|
| [category](category.md) | `val category: `[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html) |
| [defaultStorageDestinations](default-storage-destinations.md) | `val defaultStorageDestinations: `[`List`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-list/index.html)`<`[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`>`<br>Defines the names of the storages the metric defaults to when "default" is used as the destination storage. Note that every metric type will need to override this. |
| [disabled](disabled.md) | `val disabled: `[`Boolean`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) |
| [lifetime](lifetime.md) | `val lifetime: `[`Lifetime`](../-lifetime/index.md) |

### Functions

| Name | Summary |
|---|---|
| [cancel](cancel.md) | `fun cancel(): `[`Unit`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html)<br>Abort a previous [start](start.md) call. No error is recorded if no [start](start.md) was called. |
| [start](start.md) | `fun start(): `[`Unit`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html)<br>Start tracking time for the provided metric. This records an error if it’s already tracking time (i.e. start was already called with no corresponding [stopAndSum](stop-and-sum.md)): in that case the original start time will be preserved. |
| [stopAndSum](stop-and-sum.md) | `fun stopAndSum(): `[`Unit`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html)<br>Stop tracking time for the provided metric. Add the elapsed time to the time currently stored in the metric. This will record an error if no [start](start.md) was called. |
| [testGetValue](test-get-value.md) | `fun testGetValue(pingName: `[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)` = getStorageNames().first()): `[`Long`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html)<br>Returns the stored value for testing purposes only |
| [testHasValue](test-has-value.md) | `fun testHasValue(pingName: `[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)` = getStorageNames().first()): `[`Boolean`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)<br>Tests whether a value is stored for the metric for testing purposes only |

### Inherited Functions

| Name | Summary |
|---|---|
| [getStorageNames](../-common-metric-data/get-storage-names.md) | `open fun getStorageNames(): `[`List`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-list/index.html)`<`[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)`>`<br>Get the list of storage names the metric will record to. This automatically expands [DEFAULT_STORAGE_NAME](#) to the list of default storages for the metric. |
| [shouldRecord](../-common-metric-data/should-record.md) | `open fun shouldRecord(logger: `[`Logger`](../../mozilla.components.support.base.log.logger/-logger/index.md)`): `[`Boolean`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) |
