We did try this, check out the second ticket here #2, but it had so many unforseen side-effects on formatting and parsing, that we abandoned it. Feel free to fork the code and demonstrate it works, then we may revisit it, but given the built-in Date/Time library of the JDK has ultra-primitive toString()
functionality in most of its core types like DateTime
, LocalDateTime
, etc. and Instant does exactly the same default formatting:
public String toString() {
return DateTimeFormatter.ISO_INSTANT.format(this);
}
we do not feel a strong need in another value-based Java API to go beyond what the JDK felt was necessary.
Currently, both Quantity#toString and Unit#toString default to a built-in formatter, SimpleQuantityFormat and SimpleUnitFormat. I believe it would be useful to provide a way to set a custom formatter globally, especially for Quantity. Meaning any time a Quantity is converted to a String within the application it would use the provided formatter.
