Michael Beckerle updated DAFFODIL-1673:
---------------------------------------
Labels: beginner (was: )
> code quality: use non-deprecated syntax for methods that don't return a value
> -----------------------------------------------------------------------------
>
> Key: DAFFODIL-1673
> URL: https://issues.apache.org/jira/browse/DAFFODIL-1673
> Project: Daffodil
> Issue Type: Improvement
> Components: Clean Ups, Infrastructure
> Reporter: Michael Beckerle
> Priority: Major
> Labels: beginner
> Fix For: deferred
>
>
> This syntax is officially deprecated.
> {code}def someFun(x: String) { .... }
> {code}
> Instead one must write explicitly:
> {code}
> def someFun(x:String): Unit = { ... }
> {code}
> Meaning that the value of x.length is discarded and the function returns Unit
> (or () if you prefer) instead.
> I'd like to stress out that this is deprecated since Oct 29, 2013
> (https://github.com/scala/scala/pull/3076/), but the warning only shows up if
> you compile with the -Xfuture flag.
> We should turn on the -Xfuture flag, and fix this and any other deprecations
> that come up.
> We may want to write a sed-script or other automation. I have generally
> preferred the now-deprecated style in my code, so there are many many cases.
> {code}
> scala -Xfuture -deprecation
> scala> def foo {}
> <console>:1: warning: Procedure syntax is deprecated. Convert procedure `foo`
> to method by adding `: Unit =`.
> def foo {}
> foo: Unit
> {code}
