Constructor Detail

AbstractRunnablesService

public AbstractRunnablesService(java.lang.String serviceId,
                                java.io.InputStream ymlFile)

Creates a service from a service id and a YAML artifact.

Parameters:

serviceId - the service id

ymlFile - the YML file containing the YAML artifact with the service descriptor

AbstractRunnablesService

public AbstractRunnablesService(YamlService yaml)

Creates a service from YAML information.

Parameters:

yaml - the service information as read from YAML. By default, the Python executable is "ServiceEnvironment.py", which can be overridden by YamlProcess.getExecutable(). YamlProcess.getHomePath() is set to the home path where the executable was extracted to. Further, YamlProcess.getCmdArg() are taken over if given.

Method Detail

register

protected void register(AbstractProcessService.RunnableWithStop runnable)

Registers a runnable that shall be stopped in stop().

Parameters:

runnable - the runnable, ignored if null

stop

protected ServiceState stop()

Description copied from class: AbstractService

Stops the service and the background process.

Overrides:
