public Layer1ApiUpstreamRelay()

Method Details

onInstrumentAdded

public void onInstrumentAdded(String alias,
 InstrumentInfo instrumentInfo)

Description copied from interface: Layer1ApiInstrumentListener

Indicates successful subscription to the instrument

Specified by:

onInstrumentAdded in interface Layer1ApiInstrumentListener

Parameters:

onInstrumentRemoved

public void onInstrumentRemoved(String alias)

Description copied from interface: Layer1ApiInstrumentListener

Unsubscribed from instrument (user-initiated or provider initiated).
Please note that if you use this in strategy that implements OnlineCalculatable, you should not delete any data about instrument that is expected in OnlineCalculatable.calculateValuesInRange(String, String, long, long, int, velox.api.layer1.layers.strategies.interfaces.CalculatedResultListener) or OnlineCalculatable.createOnlineValueCalculator(String, String, long, java.util.function.Consumer, velox.api.layer1.layers.strategies.interfaces.InvalidateInterface), or should handle absence of that data (in case you delete it) gracefully. The reason is that you can get Layer1ApiInstrumentListener.onInstrumentRemoved(String) in the middle of OnlineCalculatable request
