AudioVolumeManager service

Instanciating the service#

Load the following scripts:

<script src="http://127.0.0.1/api/v1/shared/core.js"></script>
<script src="http://127.0.0.1/api/v1/shared/session.js"></script>
<script src="http://127.0.0.1/api/v1/audiovolumemanager/service.js"></script>

You can then get an instance of the service with code similar to:

const session = new lib_session.Session();
const sessionstate = {};
let _audiovolumeManager = null;
sessionstate.onsessionconnected = function () {
  console.log(`AudioVolumeManager onsessionconnected`);
  lib_audiovolume.AudioVolumeManager.get(session).then((AudioVolumeManagerService) => {
  console.log(`Got AudioVolumeManager : #AudioVolumeManagerService.service_id}`);
  _audiovolumeManager = AudioVolumeManagerService;
}).catch((e) => {
  console.log(`Error calling AudioVolumeManager service${JSON.stringify(e)}`);
  _audiovolumeManager = null;
});
};

sessionstate.onsessiondisconnected = function () {
  console.log(`AudioVolumeManager onsessiondisconnected Daemon Crashed`);
};

// On desktop version, set ENV WS_RUNTIME_TOKEN=secrettoken
session.open('websocket', 'localhost', 'secrettoken', sessionstate, true);

Then the developer can use _audiovolumeManager as AudioVolumeManager service instance.

This service implements the AudioVolume interface.

_audiovolumeManager.addEventListener(_audiovolumeManager.AUDIO_VOLUME_CHANGED_EVENT, handleEvent);
_audiovolumeManager.removeEventListener(_audiovolumeManager.AUDIO_VOLUME_CHANGED_EVENT, handleEvent);
