Detailed Description

RemoteViz

Represents a client application instance using RemoteViz.

In the case of HTML5 applications, a client represents a single instance of a web browser for a single domain name. See RemoteVizRenderArea.

In the case of the SoRemoteVizClient node, a client represents a single instance of the application using the node.

When a client first connects to the RemoteViz service (e.g by calling the RemoteVizRenderArea method connectTo()), a Client object is automatically created and the ServiceListener method onConnectedClient() is called with the client id. The client object can be queried using Service::getClient(). A Connection object is also created. A RenderArea object is created if the requested render area does not already exist. In any case the Connection can be queried using the getConnection() method and the associated RenderArea can be queried using the Connection::getRenderArea() method.

A service has zero clients initially and may allow one client or multiple clients (see ServiceListener methods onPendingCreateRenderArea and onPendingShareRenderArea). While the service is running, you can get the current client(s) using the Service methods getNumClients() and getClient().

A client has at least one connection but may have multiple connections if the service allows that. See the methods getNumConnections() and getConnection().

When a client is disconnected, the ServiceListener method onDisconnectedClient() is called. Following this call, the client object will no longer be referenced by RemoteViz and will be disposed unless the application holds a reference.


Member Function Documentation

void RemoteViz::Rendering::Client::disconnect (  ) 

Disconnects the client.

A KICKED disconnect message will be sent to all connections of the client, then they will be disconnected.

const std::string& RemoteViz::Rendering::Client::getApplicationName (  )  const

HTML5 client: Returns the domain name of the web host to which the client is connected.


Specifically, RemoteVizClient.js uses the JavaScript command “window.location.host”. Note that this command returns an empty string when the URL is a file path (starting with “file://”). In this case, there is no domain name.

SoRemoteVizClient node: Returns the string "SoRemoteVizClient".

Returns:
the application name.
std::shared_ptr<Connection> RemoteViz::Rendering::Client::getConnection ( unsigned int  index  )  const

Gets a Connection of the client.

See getNumConnections().

Parameters:
index : index identifying the client
Returns:
a pointer to the connection if the index exists, otherwise returns nullptr.
std::shared_ptr<Connection> RemoteViz::Rendering::Client::getConnection ( const std::string &  id  )  const

Gets a Connection of the client.

Parameters:
id : ID identifying the connection.
Returns:
a pointer to the connection if the id exists, otherwise returns nullptr.
const std::string& RemoteViz::Rendering::Client::getEnvironment (  )  const

HTML5 client: Returns the value of the user-agent header sent by the client web browser.

SoRemoteVizClient node: Returns the operating system (OS) running the client application.

Returns:
the environment.
const std::string& RemoteViz::Rendering::Client::getId (  )  const

Gets the id of the client.

The client id is a Globally Unique Identifier (GUID) created by RemoteViz.

Returns:
the ID identifying the client
unsigned int RemoteViz::Rendering::Client::getNumConnections (  )  const

Gets the number of client connections.

Returns:
the number of connections
std::shared_ptr<ClientSettings> RemoteViz::Rendering::Client::getSettings (  )  const

Gets the client settings.

Returns:
a pointer to the client settings
bool RemoteViz::Rendering::Client::isConnected (  )  const

Gets the state of the Client: connected or disconnected.

Connected (true) means the Client has at least one active Connection. When a Client is being disconnected, the ServiceListener method onDisconnectedClient() is called. Just before this call, the Client state is set to "disconnected". Following this call, the Client object will no longer be referenced by RemoteViz and will be disposed unless the application holds a reference. RemoteViz will never reuse the object internally.

Returns:
true if the client is connected or false if the client is disconnected.
bool RemoteViz::Rendering::Client::isImageStreamingSupported (  )  const

Returns if the client supports image streaming.

Returns:
true if image streaming is supported.
bool RemoteViz::Rendering::Client::isVideoStreamingSupported (  )  const

Returns if the client supports video streaming.

Returns:
true if video streaming is supported.
bool RemoteViz::Rendering::Client::sendMessage ( const std::vector< unsigned char > &  buffer  ) 

Sends a binary message to all the connections of the client.

Parameters:
buffer : the binary buffer to be sent to all connections of the client
excludedConnections : optional - the connections that should not receive the message.
Returns:
true if the message has been successfully sent to all connections, otherwise returns false.
bool RemoteViz::Rendering::Client::sendMessage ( const std::string &  message  ) 

Sends a text message to all the connections of the client.

Parameters:
message : the message to be sent to all the connections of the client
excludedConnections : optional - the connections that should not receive the message.
Returns:
true if the message has been successfully sent to all connections, otherwise returns false.
