Interface MarketStream

All Known Implementing Classes:

WebsocketMarketStream

public interface MarketStream

Represents the stream of realtime public trade data streamed from Quedex and allows registering and subscribing for particular data types. The registered listeners will be called (in a single thread) for every event that arrives. The data come in form of PGP-clearsigned JSON messages - all the verification and deserialization is handled by the implementations and the listeners receive Java objects.

The stream gives the following guarantees useful for state initialisation:

• InstrumentsListener will be always called immediately after connection is established, before any other listener
• after the connection is established, every listener is guaranteed to be called at least once

To handle all errors properly, always registerStreamFailureListener(net.quedex.api.common.StreamFailureListener) before start()ing the stream.
