Syntax

class IIdentifiableXRDevice : public IXRSystemIdentifier

Remarks

Generic device identifier interface

This class is meant to provide a way to identify and distinguish XR devices across various XR systems in a platform-agnostic way.

Additionally, it can be used to tie various IModularFeature device interfaces together. For example, if you have separate IXRTrackingSystem and IXRSystemAssets interfaces which both reference the same devices, then this base class gives you a way to communicate between the two.

Functions

		Name	Description
	int32	GetSystemDeviceId()	Returns a unique identifier that can be used to reference this device within the system is belongs to.
