[jira] [Commented] (GEOMETRY-125) DoubleFormats Builder

["Gilles Sadowski (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GEOMETRY-125?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17362351#comment-17362351 ] 

Gilles Sadowski commented on GEOMETRY-125:
------------------------------------------

bq. {{build()}} [vs] {{buildScientific()}}

An {{enum}}, maybe? ;-)

{code}
public enum DoubleFormat {
    PLAIN( /* ... */),
    SCIENTIFIC( /* ... */ ),
    ENGINEER( /* ... */ ),
    DEFAULT( /* ... */ )

    // ...
}
{code}

> Use a {{Builder}} class in {{DoubleFormats}} to make the API more self-documenting. Ex:
> {code:java}
> // current
> DoubleFunction<String> def = DoubleFormats.createDefault(5, -3);
> DoubleFunction<String> sci = DoubleFormats.createScientific(5, -3);
> // new
> DoubleFunction<String> def = DoubleFormats.builder()
>     .withMaxPrecision(5)
>     .withMinExponent(-3)
>     .build();
> DoubleFunction<String> sci = DoubleFormats.builder()
>     .withMaxPrecision(5)
>     .withMinExponent(-3)
>     .buildScientific();
> {code}
