Method Detail

initialize

public final void initialize(ReportingInitializationContext config)
                      throws InitializationException

Description copied from interface: ReportingTask

Provides the Reporting Task with access to objects that may be of use throughout the life of the service

Specified by:

initialize in interface ReportingTask

Parameters:

config - of initialization context

Throws:

InitializationException - if unable to init

getControllerServiceLookup

protected final ControllerServiceLookup getControllerServiceLookup()

Returns:

the ControllerServiceLookup that was passed to the initialize(ReportingInitializationContext) method

getNodeTypeProvider

protected final NodeTypeProvider getNodeTypeProvider()

Returns:

the NodeTypeProvider that was passed to the initialize(ReportingInitializationContext) method

getIdentifier

public String getIdentifier()

Specified by:

getIdentifier in interface ConfigurableComponent

Returns:

the identifier of this Reporting Task

getName

protected String getName()

Returns:

the name of this Reporting Task

setComponentInfo

@OnScheduled
public void setComponentInfo(ConfigurationContext context)

Sets various component information using the given context

Parameters:

context - the context to use for this reporting task

getSchedulingPeriod

protected long getSchedulingPeriod(TimeUnit timeUnit)

Parameters:

timeUnit - of scheduling period

Returns:

the amount of times that elapses between the moment that this ReportingTask finishes its invocation of ReportingTask.onTrigger(ReportingContext) and the next time that ReportingTask.onTrigger(ReportingContext) is called.

init

protected void init(ReportingInitializationContext config)
             throws InitializationException

Provides a mechanism by which subclasses can perform initialization of the Reporting Task before it is scheduled to be run

Parameters:

config - context

Throws:

InitializationException - if failure to init

getLogger

protected ComponentLog getLogger()

Returns:

the logger that has been provided to the component by the framework in its initialize method
