public class XRSession
extends EventTarget

The WebXR Device API's XRSession interface represents an ongoing XR session, providing methods and properties used to interact with and control the session. To open a WebXR session, use the XRSystem interface's requestSession() method.

Method Summary

Modifier and Type	Method and Description
void	cancelAnimationFrame(int handle) The cancelAnimationFrame() method of the XRSession interface cancels an animation frame which was previously requested by calling requestAnimationFrame.
@JsNonNull Promise<java.lang.Void>	end() The end() method shuts down the XRSession on which it's called, returning a promise which resolves once the session has fully shut down.
java.lang.Double	frameRate()
XRInputSourceArray	inputSources() The read-only inputSources property of the XRSession interface returns an XRInputSourceArray object which lists all controllers and input devices which are expressly associated with the XR device and are currently available.
XRRenderState	renderState() The read-only renderState property of an XRSession object indicates the returns a XRRenderState object describing how the user's environment which should be rendered.
int	requestAnimationFrame(XRFrameRequestCallback callback) The XRSession method requestAnimationFrame(), much like the Window method of the same name, schedules a callback to be executed the next time the browser is ready to paint the session's virtual environment to the XR display.
@JsNonNull Promise<XRReferenceSpace>	requestReferenceSpace(java.lang.String type) The requestReferenceSpace() method of the XRSession interface returns a promise that resolves with an instance of either XRReferenceSpace or XRBoundedReferenceSpace as appropriate given the type of reference space requested.
Float32Array	supportedFrameRates()
void	updateRenderState() The updateRenderState() method of the XRSession interface of WebXR API schedules changes to be applied to the active render state prior to rendering of the next frame.
void	updateRenderState(XRRenderStateInit state) The updateRenderState() method of the XRSession interface of WebXR API schedules changes to be applied to the active render state prior to rendering of the next frame.
@JsNonNull Promise<java.lang.Void>	updateTargetFrameRate(float rate)
java.lang.String	visibilityState() The read-only visibilityState property of the XRSession interface is a string indicating whether the WebXR content is currently visible to the user, and if it is, whether it's the primary focus.
