5.6.3. Classes

class AudioEncodePipeline

A wrapper for an avs::AudioEncoder and an avs::Pipeline.

class AudioEncoder : public avs::AudioEncoderBackendInterface

Implementation of the default audio encoding.

struct ClientNetworkContext

Wrapper for the network pipeline objects for a given client. //

class ClientData

Data object for a connected client.

Public Functions

void reparentNode(avs::uid nodeID)

Called after reparenting to inform the client of the new parent.

class ClientManager

Container for the client-specific data objects.

class ClientMessaging : public avs::GenericTargetInterface

Per-client messaging handler.

Public Functions

void streamNode(avs::uid nodeID)

Mark this node as being needed by the client.

void unstreamNode(avs::uid nodeID)

Mark this node as being NOT needed by the client.

class SignalingService

Signaling service for establishing connections with clients.

class GeometryEncoder : public avs::GeometryEncoderBackendInterface

Backend implementation of the geometry encoder.

class GeometryStore

Singleton for storing geometry data and managing the geometry file cache. The definitive geometry store is the file structure pointed to by SetCachePath(). The structure in GeometryStore is the session structure, using uid’s for quick reference.

Public Functions

bool CheckForErrors()

Check for errors - these should be resolved before using this store in a server.

avs::uid GetOrGenerateUid(const std::string &path)

Get or generate a uid. If the path already corresponds to an id, that will be returned. Otherwise a new one will be added.

avs::uid PathToUid(std::string p) const

Get the current session uid corresponding to the given resource/asset path.

std::string UidToPath(avs::uid u) const

Get the resource/asset path corresponding to the current session uid.

class GeometryStreamingService : public avs::GeometryRequesterBackendInterface

This per-client class tracks the resources and nodes that the client needs, and returns them via GeometryRequesterBackendInterface to the encoder.

Subclassed by teleport::server::PluginGeometryStreamingService

Public Functions

virtual avs::RenderingFeatures getClientRenderingFeatures() const override

Returns the rendering features the client supports.

class HTTPService

Interface for http services.

Subclassed by teleport::server::DefaultHTTPService

class DefaultHTTPService : public teleport::server::HTTPService

Default service for HTTP download of resources from the Teleport server.

class NetworkPipeline

Network pipeline.

struct ServerSettings

Settings specific to the server state, shared across all clients.

class SourceNetworkPipeline
class VideoEncodePipeline

Wrapper for the video encoding pipeline objects.
