PerformanceMeasure is an abstract interface for PerformanceEntry objects with an entryType of "measure". Entries of this type are created by calling performance.measure() to add a named DOMHighResTimeStamp (the measure) between two marks to the browser's performance timeline.

Properties

This interface has no properties but it extends the following PerformanceEntry properties by qualifying/constrainting the properties as follows:

PerformanceEntry.entryType
Returns "measure".
PerformanceEntry.name
Returns the name given to the measure when it was created via a call to performance.measure().
PerformanceEntry.startTime
Returns a timestamp given to the measure when performance.measure() was called.
PerformanceEntry.duration
Returns a DOMHighResTimeStamp that is the duration of the measure (typically, the measure's end mark timestamp minus its start mark timestamp).

Methods

This interface has no methods.

Example

See the example in Using the User Timing API.
