Detailed Description

Remote access to VirtualFile service that resides in kanziconnect server.

Constructor & Destructor Documentation

VirtualFileRemoteClient()

kanzi::connect::VirtualFileRemoteClient::VirtualFileRemoteClient ( ClientSharedPtr  client )

protected

c++ constructor - initializes the object

Parameters

client

Member Function Documentation

create()

static VirtualFileRemoteClientSharedPtr kanzi::connect::VirtualFileRemoteClient::create ( ClientSharedPtr  client )

static

Factory method to create object.

Parameters

client

pointer to client

Returns

newly allocated remote client instance.

getPath()

string kanzi::connect::VirtualFileRemoteClient::getPath ( RegistrationToken  token ) const

virtual

Retrieve the path associated with the registration.

Parameters

token

The token that identifies the registration.

Returns

full path in form: http://<server>:8080/somepath/ empty string is returned if registration has failed, or it is still in progress.

Implements kanzi::connect::VirtualFileClient.

onConnectionStateChanged()

void kanzi::connect::VirtualFileRemoteClient::onConnectionStateChanged ( Connection::State  state )

protected

Invoked when ever connection state changes.

Parameters

state

new state.

registerPath()

RegistrationToken kanzi::connect::VirtualFileRemoteClient::registerPath ( const string &  scheme, const string &  pathProposal, VirtualFileProvider *  provider  )

virtual

Registers a path to HTTP Server.

Registration is an asynchronous operation for remote clients.

Parameters

scheme	Requested protocol. Either HTTP or HTTPS expected. If you do not set a value, uses HTTP.
pathProposal	clients proposal of the path where the serving is to be done.
provider	pointer to callback interface that is, if successfully registered, invoked for every file request made under the registered path. Caller must guarantee that the provided callback interface remains valid until corresponding unregisterPath call is made.

Returns

Opaque token that identifies this registration.

Implements kanzi::connect::VirtualFileClient.

registerRegistrationStatusChangeCallback()

void kanzi::connect::VirtualFileRemoteClient::registerRegistrationStatusChangeCallback ( RegistrationToken  token, RegistrationStatusChangeCallback *  callback  )

virtual

Register registration status change callback.

Registration is meaningful only for remote clients since status does not change for local clients.

Parameters

token	identification token.
callback	interface to be invoked when registration status changes.

Reimplemented from kanzi::connect::VirtualFileClient.

registrationStatus()

RegistrationStatus kanzi::connect::VirtualFileRemoteClient::registrationStatus ( RegistrationToken  token )

virtual

Checks the registration status.

For remote operations registration is asynchronous and thus it is not complete until this method returns either Registered or RegistrationFailed. Also, if for example connection is lost, then the registration status changes even if it has been completed earlier.

Parameters

token

The token that identifies the registration.

Returns

enumerated status.

Implements kanzi::connect::VirtualFileClient.

unregisterPath()

void kanzi::connect::VirtualFileRemoteClient::unregisterPath ( RegistrationToken  token )

virtual

Unregisters previously registered path.

Parameters

token

opaque handle got using the registerPath

Implements kanzi::connect::VirtualFileClient.

unregisterRegistrationStatusChangeCallback()

void kanzi::connect::VirtualFileRemoteClient::unregisterRegistrationStatusChangeCallback ( RegistrationToken  token )

virtual

Clears previously registered status change callback.

Parameters

token

path registration token.

Reimplemented from kanzi::connect::VirtualFileClient.
