Delegates

[danp11]

Hi all,

As records favor composition, I wanted to discuss with you if an additional interface, for example
public interface Delegates extends With
could be something that would make sence?

Let say we have a record
public record Trade(TradeInfo tradeInfo) implements TradeBuilder.With

where TradeInfo looks like this:
public record TradeInfo(String orderbookId, String tradeId) {}

this delegate interface could look something like this

public interface Delegates extends With {

        default String orderbookId() {
            return tradeInfo().orderbookId();
        }

        default String tradeId() {
            return tradeInfo().tradeId();
        }
    }

This would let us specify trade.tradeId instead of trade.tradeInfo.tradeId when we are using the trade record.

What are your thoughts about this delegate interface?

Regards
Dan

This seems like a lot of work just to write trade.tradeId() instead of trade().tradeInfo().tradeId(). I'm -1 on this. Also, this isn't in the category of "building records". Maybe others will have some ideas on this.

Hi, I understand that it is out of scope for this project.

It's just when modelling large modells with record blocks the delegates would save alot of "extra getter code"

You can close this discussion.

We can leave it open - maybe others have more ideas
