Method Detail

start

public void start(StartContext context)
           throws StartException

Deprecated.

Start the service. Do not return until the service has been fully started, unless an asynchronous service start is performed. All injections will be complete before this method is called.

If the service start involves any activities that may block, the asynchronous mechanism provided by the context should be used. See the class javadoc for details.

Specified by:

start in interface Service

Specified by:

start in interface Service<T>

Parameters:

context - the context which can be used to trigger an asynchronous service start

Throws:

StartException - if the service could not be started for some reason

stop

public void stop(StopContext context)

Deprecated.

Stop the service. Do not return until the service has been fully stopped, unless an asynchronous service stop is performed. All injections will remain intact until the service is fully stopped. This method should not throw an exception.

If the service start involves any activities that may block, the asynchronous mechanism provided by the context should be used. See the class javadoc for details.

Specified by:

stop in interface Service

Specified by:

stop in interface Service<T>

Parameters:

context - the context which can be used to trigger an asynchronous service stop

getValue

public T getValue()
           throws IllegalStateException

Deprecated.

Get the actual dependency value.

Specified by:

Returns:

the actual dependency value

Throws:

IllegalStateException - if the value is time-sensitive and the current state does not allow retrieval.
