Interface Layer1ApiAdvancedGeneratorCreator

public interface Layer1ApiAdvancedGeneratorCreator

Normally when settings are changed (e.g. via chart settings inherit option), strategy will be finished via Layer1ApiFinishable.finish() and started via UserMessageLayersChainCreatedTargeted. If strategy generates custom events, normally it would create and add generator every on UserMessageLayersChainCreatedTargeted message. Generating events can take considerable time.
This interface allows you to handle event generation in such cases gracefully.
It will call onAddGenerators() every time data has changes (e.g. as new feed is being loaded)
onRemoveIndicators() when added indicators should be removed due to data change
onSettingsChanged() every time settings has been changed.
Note: don't use this interface for managing event generators that rely on settings that can be changed
