Marker annotation a Processor,
ControllerService,
FlowRegistryClient,
ParameterProvider,
FlowAnalysisRule, or
ReportingTask implementation
can use to indicate a method should be called whenever the component is added
to the flow. This method will be called once for the entire life of a
component instance.
Methods with this annotation are called without any arguments, as all settings and properties can be assumed to be the defaults.
