Class BaseFlux<T>

java.lang.Object

tech.cassandre.trading.bot.util.base.Base

tech.cassandre.trading.bot.util.base.batch.BaseFlux<T>

Type Parameters:

T - flux

Direct Known Subclasses:

AccountFlux, OrderFlux, PositionFlux, TickerFlux, TradeFlux

public abstract class BaseFlux<T>
extends Base

Base flux.

update() method is called by schedulers, and it does two things: - Calls the getNewValues() method you implemented to retrieve new values from "outside" (for example: call the service to retrieve new tickers). - For each value retrieved previously, we call the saveValues() method you implemented to save all the data in the database. - Each value saved in database is then push to the flux to be consumed by strategies. note: you are not forced to implement getNewValues() or saveValues().
