Gigamap of different types

[hrstoyanov]

I am trying to use a Gigamap for different classes, all implementing a base interface - is using instanceof (and possibly returning null) in the indexer a good approach? IS returning NULL from getString() OK - could not find anything in the javadocs for the Gigamap sources)?

public interface ZAuditEvent {

    AuditTrace auditTrace();
    record Default(AuditTrace auditTrace, String operation, String details) implements ZAuditEvent {}
   
   IndexerString<ZAuditEvent> OPERATION_INDEX = new IndexerString.Abstract<>() {
        @Override
        protected String getString(final ZAuditEvent entity) {
            if (entity instanceof ZAuditEvent.Default defaultEvent) {
                return defaultEvent.operation();
            }
            return null;
        }
    };

   class Store {

        private final GigaMap<ZAuditEvent> map = GigaMap.<ZAuditEvent>Builder()
                ...
                .withBitmapIndex(OPERATION_INDEX)
                .build();
  
}

Confirmed it works
