Constructor Detail

BeaconSender

public BeaconSender(Logger logger,
                    HTTPClientConfiguration httpClientConfiguration,
                    HTTPClientProvider clientProvider,
                    TimingProvider timingProvider)

Create a new BeaconSender.

To start the beacon sending the initialize() method must be called.

Parameters:

logger - Logger for logging messages

httpClientConfiguration - Initial HTTP client configuration.

clientProvider - Used for retrieving an HTTPClient instance.

timingProvider - Used for some timing related things.

Method Detail

initialize

public void initialize()

Start beacon sender thread.

Note: The beacon sender has to perform some initialization code, which is done in the background, before it actually starts sending beacons. If it's necessary to have OpenKit fully initialized use the waitForInit() method to wait until initialized.

waitForInit

public boolean waitForInit()

Wait until OpenKit is fully initialized or a shutdown request has been made.

This method might hang forever.

Returns:

true if OpenKit is fully initialized, or false if shutdown has been requested during init phase.

waitForInit

public boolean waitForInit(long timeoutMillis)

Wait until OpenKit is fully initialized or a shutdown request has been made or given timeout expired.

Parameters:

timeoutMillis - The maximum number of milliseconds to wait for initialization being completed.

Returns:

true if OpenKit is fully initialized, or false if shutdown has been requested during init phase.

isInitialized

public boolean isInitialized()

Get a boolean indicating whether OpenKit has been initialized or not.

Returns:

true if OpenKit has been initialized, false otherwise.

shutdown

public void shutdown()

Shutdown the BeaconSender and wait until it's shutdown (at most SHUTDOWN_TIMEOUT milliseconds.

getLastServerConfiguration

public ServerConfiguration getLastServerConfiguration()

Returns the last known server configuration.

getCurrentServerId

public int getCurrentServerId()

Returns the current server ID to be used for creating new sessions

addSession

public void addSession(SessionImpl session)

Adds the given session to the known sessions of this BeaconSender.

This method should be called when creating a new session.

Parameters:

session - the session to start.
