Specified by:

init in interface Service

Overrides:

init in class AbstractService

start

public void start()

Description copied from class: AbstractService

Start the service. The transition should be from Service.STATE.INITED to Service.STATE.STARTED unless the operation failed and an exception was raised.

stop

public void stop()

Description copied from class: AbstractService

Stop the service. This operation must be designed to complete regardless of the initial state of the service, including the state of all its internal fields.

Specified by:

stop in interface Service

Overrides:

stop in class AbstractService
