Class XRLoaderHelper

XR Loader abstract subclass used as a base class for specific provider implementations. Class provides some helper logic that can be used to handle subsystem handling in a typesafe manner, reducing potential boilerplate code.

Syntax

public abstract class XRLoaderHelper : XRLoader

Fields

m_SubsystemInstanceMap

Map of loaded susbsystems. Used so we don't always have to fo to XRSubsystemManger and do a manual search to find the instance we loaded.

Declaration

protected Dictionary<Type, ISubsystem> m_SubsystemInstanceMap

Field Value

Type	Description
Dictionary<Type, ISubsystem>

Methods

CreateIntegratedSubsystem<TDescriptor, TSubsystem>(List<TDescriptor>, string)

Creates a native, integrated subsystem given a list of descriptors and a specific subsystem id. DEPRECATED: Please use the geenric CreateSubsystem method. This method is soley retained for backwards compatibility and will be removed in a future release.

Declaration

[Obsolete("This method is obsolete. Please use the geenric CreateSubsystem method.", false)]
protected void CreateIntegratedSubsystem<TDescriptor, TSubsystem>(List<TDescriptor> descriptors, string id) where TDescriptor : IntegratedSubsystemDescriptor where TSubsystem : IntegratedSubsystem

Parameters

Type	Name	Description
List<TDescriptor>	descriptors	List of TDescriptor instances to use for subsystem matching.
string	id	The identifier key of the particualr subsystem implementation being requested.

Type Parameters

Name	Description
TDescriptor	The descriptor type being passed in.
TSubsystem	The subsystem type being requested

CreateStandaloneSubsystem<TDescriptor, TSubsystem>(List<TDescriptor>, string)

Creates a managed, standalone subsystem given a list of descriptors and a specific subsystem id. DEPRECATED: Please use the geenric CreateSubsystem method. This method is soley retained for backwards compatibility and will be removed in a future release.

Declaration

[Obsolete("This method is obsolete. Please use the generic CreateSubsystem method.", false)]
protected void CreateStandaloneSubsystem<TDescriptor, TSubsystem>(List<TDescriptor> descriptors, string id) where TDescriptor : SubsystemDescriptor where TSubsystem : Subsystem

Parameters

Type	Name	Description
List<TDescriptor>	descriptors	List of TDescriptor instances to use for subsystem matching.
string	id	The identifier key of the particualr subsystem implementation being requested.

Type Parameters

Name	Description
TDescriptor	The descriptor type being passed in.
TSubsystem	The subsystem type being requested

CreateSubsystem<TDescriptor, TSubsystem>(List<TDescriptor>, string)

Creates a subsystem given a list of descriptors and a specific subsystem id.

You should make sure to destroy any subsystem that you created so that resources acquired by your subsystems are correctly cleaned up and released. This is especially important if you create them during initialization, but initialization fails. If that happens, you should clean up any subsystems created up to that point.

Declaration

protected void CreateSubsystem<TDescriptor, TSubsystem>(List<TDescriptor> descriptors, string id) where TDescriptor : ISubsystemDescriptor where TSubsystem : ISubsystem

Parameters

Type	Name	Description
List<TDescriptor>	descriptors	List of TDescriptor instances to use for subsystem matching.
string	id	The identifier key of the particualr subsystem implementation being requested.

Type Parameters

Name	Description
TDescriptor	The descriptor type being passed in.
TSubsystem	The subsystem type being requested

Deinitialize()

Override of Deinitialize() to provide for clearing the instance map.true

If you override this method in your subclass, you must call the base implementation to allow the instance map tp be cleaned up correctly.

Declaration

public override bool Deinitialize()

Returns

Type	Description
bool	True if de-initialization was successful.

Overrides

XRLoader.Deinitialize()

DestroySubsystem<T>()

Destroy a subsystem instance of a given type. Subsystem assumed to already be loaded from a previous call to CreateSubsystem

Declaration

protected void DestroySubsystem<T>() where T : class, ISubsystem

Type Parameters

Name	Description
T	A subclass of UnityEngine.ISubsystem

GetLoadedSubsystem<T>()

Gets the loaded subsystem of the specified type. Implementation dependent as only implemetnations know what they have loaded and how best to get it..

Declaration

public override T GetLoadedSubsystem<T>() where T : class, ISubsystem

Returns

Type	Description
T	The loaded subsystem or null if not found.

Type Parameters

Name	Description
T	Type of the subsystem to get.

Overrides

XRLoader.GetLoadedSubsystem<T>()

StartSubsystem<T>()

Start a subsystem instance of a given type. Subsystem assumed to already be loaded from a previous call to CreateSubsystem

Declaration

protected void StartSubsystem<T>() where T : class, ISubsystem

Type Parameters

Name	Description
T	A subclass of UnityEngine.ISubsystem

StopSubsystem<T>()

Stop a subsystem instance of a given type. Subsystem assumed to already be loaded from a previous call to CreateSubsystem

Declaration

protected void StopSubsystem<T>() where T : class, ISubsystem

Type Parameters

Name	Description
T	A subclass of UnityEngine.ISubsystem

WasAssignedToBuildTarget(BuildTargetGroup)

Parameters

Type	Name	Description

WasUnassignedFromBuildTarget(BuildTargetGroup)

Declaration

public virtual void WasUnassignedFromBuildTarget(BuildTargetGroup buildTargetGroup)

Parameters
