feature: constructor method that returns builder

[caleb-cushing0-kr]

@Value.Immutable
public interface FindCustomerCommand {

    @Value.Parameter
    String getCorrelationId();

    @Nullable
    String getFieldsGroups();

I'd love to have have a @Value.Style setting that allows me to have the constructor return the builder, so that I can have required parameters set by the constructor.

ImmutableFindCustomerCommand.of("correlationId").fieldGroups("...").build();

I know this is similar to staged, but when it's only one or two parameters, that seems kind of overkill.

@Style(allMandatoryParameters=true) can help you, but in for such cases / and overall small amount of fields we just stick to using with-methods. If you copy object (shallowly) couple of times in the close lines of code, with high chances of escape-analysis eliminating some allocations, it may be as efficient as builder.

ImmutableFindCustomerCommand.of("correlationId").withFieldGroups("...");
