Constructor Details

Layer1ApiInjectorRelay

public Layer1ApiInjectorRelay(Layer1ApiProvider provider)

Method Details

inject

protected void inject(java.lang.Runnable r)

Inject runnable into messages stream provider -> gui. Event is handled asynchronously. If you need to inject event synchronously and/or from the same thread - take a look at injectSynchronously(Runnable)

injectSynchronously

protected void injectSynchronously(java.lang.Runnable r)

Inject runnable into messages stream provider -> gui from the same thread. Blocks until event is injected. Be careful when using this method, it's easy to cause a deadlock. If in doubt - use inject(Runnable) instead.

safeInject

@Deprecated protected void safeInject(java.lang.Runnable r)

Deprecated.

Inject runnable into messages stream provider -> gui. If exception happens this method will log it, but won't crash the application (this was a behavior that appeared by accident). Use inject(Runnable) instead.

close

public void close()

Description copied from class: Layer1ApiUpstreamRelay

Stop relaying data. Will not let send new events upwards, but is not guaranteed to stop ones already in progress.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface Layer1ApiAdminProvider

Overrides:

close in class Layer1ApiRelay

onInstrumentAdded

public void onInstrumentAdded(java.lang.String alias, InstrumentInfo instrumentInfo)

Description copied from interface: Layer1ApiInstrumentListener

Indicates successful subscription to the instrument

Specified by:

onInstrumentAdded in interface Layer1ApiInstrumentListener

Overrides:

onInstrumentAdded in class Layer1ApiUpstreamRelay

Parameters:

alias - instrument alias

instrumentInfo - instrument specifications

onInstrumentRemoved

public void onInstrumentRemoved(java.lang.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

Specified by:

onInstrumentRemoved in interface Layer1ApiInstrumentListener

Overrides:

onInstrumentRemoved in class Layer1ApiUpstreamRelay
