Class QRCodeMiniManager

The QRCodeMiniManager is a simple wrapper around the Microsoft.MixedReality.QR.QRCodeWatcher, to reissue qr code events on the main thread, where they can be acted on safely.

Inheritance

Object

QRCodeMiniManager

Namespace: Microsoft.MixedReality.WorldLocking.Samples.Advanced.QRSpacePins

Assembly: cs.temp.dll.dll

Syntax

public class QRCodeMiniManager : MonoBehaviour

Remarks

The events are slightly simplified to the uniform pattern of the void QRCodeFunction(qrCode) defined here. No other interpretation or processing of the events is done. Events are received (on another thread) from the QRCodeWatcher, then reissued on the main thread in the next Update loop. Note that since they are received asynchronously, no exact guarantees can be made about the order in which they are called on the main thread. But in general (and in best effort) they will be called in the order in which the asynchronous events are dispatched, and on the next Update after the events are originally invoked.
