class PerformanceObserverEntryList
Usage in Deno
```typescript import { PerformanceObserverEntryList } from "node:node__perf_hooks.d.ts"; ```Returns a list of `PerformanceEntry` objects in chronological order
with respect to `performanceEntry.startTime`.
```js
import {
performance,
PerformanceObserver,
} from 'node:perf_hooks';
const obs = new PerformanceObserver((perfObserverList, observer) => {
console.log(perfObserverList.getEntries());
* [
* PerformanceEntry {
* name: 'test',
* entryType: 'mark',
* startTime: 81.465639,
* duration: 0,
* detail: null
* },
* PerformanceEntry {
* name: 'meow',
* entryType: 'mark',
* startTime: 81.860064,
* duration: 0,
* detail: null
* }
* ]
performance.clearMarks();
performance.clearMeasures();
observer.disconnect();
});
obs.observe({ type: 'mark' });
performance.mark('test');
performance.mark('meow');
```
getEntriesByName(name: string,type?: EntryType,): PerformanceEntry[]
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 to`type`.
```js
import {
performance,
PerformanceObserver,
} from 'node:perf_hooks';
const obs = new PerformanceObserver((perfObserverList, observer) => {
console.log(perfObserverList.getEntriesByName('meow'));
* [
* PerformanceEntry {
* name: 'meow',
* entryType: 'mark',
* startTime: 98.545991,
* duration: 0,
* detail: null
* }
* ]
console.log(perfObserverList.getEntriesByName('nope')); // []
console.log(perfObserverList.getEntriesByName('test', 'mark'));
* [
* PerformanceEntry {
* name: 'test',
* entryType: 'mark',
* startTime: 63.518931,
* duration: 0,
* detail: null
* }
* ]
console.log(perfObserverList.getEntriesByName('test', 'measure')); // []
performance.clearMarks();
performance.clearMeasures();
observer.disconnect();
});
obs.observe({ entryTypes: ['mark', 'measure'] });
performance.mark('test');
performance.mark('meow');
```
getEntriesByType(type: EntryType): PerformanceEntry[]
Returns a list of `PerformanceEntry` objects in chronological order
with respect to `performanceEntry.startTime` whose `performanceEntry.entryType` is equal to `type`.
```js
import {
performance,
PerformanceObserver,
} from 'node:perf_hooks';
const obs = new PerformanceObserver((perfObserverList, observer) => {
console.log(perfObserverList.getEntriesByType('mark'));
* [
* PerformanceEntry {

* duration: 0,
* detail: null
* }
* ]
performance.clearMarks();
performance.clearMeasures();
observer.disconnect();
});
obs.observe({ type: 'mark' });
performance.mark('test');
performance.mark('meow');
