fun getEntriesByName(name: String, type: EntryType = definedExternally): ReadonlyArray<PerformanceEntry>(source)

Returns a list of PerformanceEntry objects in chronological order with respect to performanceEntry.startTime whose performanceEntry.name is equal to name, and optionally, whose performanceEntry.entryType is equal totype.
