web.performance.Performance — clojure-interop/cljs-web-api 1.0.4

The Performance interface provides access to performance-related for the current page. It's part of the High Resolution Time API, is enhanced by the Performance Timeline API, the Navigation Timing the User Timing API, and the Resource Timing API.

clear-marks cljs

(clear-marks this & args)

Method.

The clearMarks() method removes the named mark from the browser's entry buffer. If the method is called with no arguments, all entrieswith anentry type` of "mark" will be removed from performance entry buffer.

performance.clearMarks(); performance.clearMarks(name);

clear-measures cljs

(clear-measures this & args)

Method.

The clearMeasures() method removes the named measure from the performance entry buffer. If the method is called with no arguments, performance entries with an entry type of "measure" will removed from the performance entry buffer.

performance.clearMeasures(); performance.clearMeasures(name);

clear-resource-timings cljs

(clear-resource-timings this)

Method.

The clearResourceTimings() method removes all performance entries an entryType of "resource" from the browser's performance buffer and sets the size of the performance data buffer to zero. set the size of the browser's performance data buffer, use the method.

performance.clearResourceTimings();

get-entries cljs

(get-entries this & args)

Method.

The getEntries() method returns a list of all web.performance.PerformanceEntry for the page. The list's members (entries) can be created by performance marks or measures (for example by calling the mark() at explicit points in time. If you are only interested in performance of certain types or that have certain names, see getEntriesByType() getEntriesByName().

`General syntax:

entries = window.performance.getEntries();`

get-entries-by-name cljs

(get-entries-by-name this name type)

Method.

The getEntriesByName() method returns a list of web.performance.PerformanceEntry for the given name and type. The list's members (entries) can created by making performance marks or measures (for example calling the mark() method) at explicit points in time.

entries = window.performance.getEntriesByName(name, type);

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/getEntriesByName

get-entries-by-type cljs

(get-entries-by-type this type)

Method.

The getEntriesByType() method returns a list of web.performance.PerformanceEntry for a given type. The list's members (entries) can be created making performance marks or measures (for example by calling mark() method) at explicit points in time.

entries = window.performance.getEntriesByType(type);

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/getEntriesByType

mark cljs

(mark this name)

Method.

The mark() method creates a timestamp in the browser's performance buffer with the given name. The application defined timestamp be retrieved by one of the web.performance.Performance interface's methods (getEntries(), getEntriesByName() or getEntriesByType()).

performance.mark(name);

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/mark

measure cljs

(measure this & args)

Method.

The measure() method creates a named timestamp in the browser's entry buffer between marks, the navigation start time, or the time. When measuring between two marks, there is a start mark end mark, respectively. The named timestamp is referred to as measure.

performance.measure(name); performance.measure(name, startMark); performance.measure(name, startMark, endMark); performance.measure(name, undefined, endMark);

navigation cljs

(navigation this)

Property.

The legacy Performance.navigation read-only property returns web.deprecated.PerformanceNavigation object representing the of navigation that occurs in the given browsing context, such the number of redirections needed to fetch the resource.

navObject = performance.navigation;

now cljs

(now this)

Method.

The performance.now() method returns a web.dom.DOMHighResTimeStamp, in milliseconds.

t = performance.now();

onresourcetimingbufferfull cljs

(onresourcetimingbufferfull this)

Property.

The onresourcetimingbufferfull property is an event handler that be called when the resourcetimingbufferfull event is fired. This is fired when the browser's resource timing performance buffer full.

callback = performance.onresourcetimingbufferfull = buffer_full_cb;

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/onresourcetimingbufferfull

set-onresourcetimingbufferfull! cljs

(set-onresourcetimingbufferfull! this val)

Property.

The onresourcetimingbufferfull property is an event handler that be called when the resourcetimingbufferfull event is fired. This is fired when the browser's resource timing performance buffer full.

callback = performance.onresourcetimingbufferfull = buffer_full_cb;

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/onresourcetimingbufferfull

set-resource-timing-buffer-size cljs

(set-resource-timing-buffer-size this max-size)

Method.

The setResourceTimingBufferSize() method sets the browser's resource buffer size to the specified number of "resource" performance type objects.

performance.setResourceTimingBufferSize(maxSize);

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/setResourceTimingBufferSize

set-time-origin! cljs

(set-time-origin! this val)

Property.

The timeOrigin read-only property of the web.performance.Performance returns the high resolution timestamp of the start time of the measurement.

var timeOrigin = performance.timeOrigin

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/timeOrigin

time-origin cljs

(time-origin this)

Property.

The timeOrigin read-only property of the web.performance.Performance returns the high resolution timestamp of the start time of the measurement.

var timeOrigin = performance.timeOrigin

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/timeOrigin

timing cljs

(timing this)

Property.

The legacy Performance.timing read-only property returns a web.deprecated.PerformanceTiming containing latency-related performance information.

timingInfo = performance.timing;

See also: https://developer.mozilla.org/en-US/docs/Web/API/Performance/timing

to-json cljs

(to-json this)

Method.

The toJSON() method of the web.performance.Performance interface a standard serializer: it returns a JSON representation of the object's properties.

myPerf = performance.toJSON()
