PerformanceEntry class

The object encapsulates a single performance metric that is part of the performance timeline. A performance entry can be directly created by making a performance mark or measure (for example by calling the mark() method) at an explicit point in an application. Performance entries are also created in indirect ways such as loading a resource (such as an image). instances will always be one of the following subtypes:

PerformanceMark PerformanceMeasure PerformanceNavigationTiming PerformanceResourceTiming PerformancePaintTiming
