Static Fields

[consiliens]

How does one access a qualified static field in Xtend2?

import java.io.File
String separator = File.separator // fails
String separator2 = java.io.File.separator // fails

While a wildcard static import works, it's not the same.

import static java.io.File.*
String separator3 = separator

Use :: i.e. - 

val separator = File::separator 

val separator2 = java::io::File::separator

It doesn't work.

package xtend.tutorial.basicsimport java.io.File
class Xtend01_HelloWorld {
// mismatched input 'val' expecting '}'val separator2 =
java::io::File::separator}

Gmail removed the code formatting. Here's a Gist link.

Hi,

the following is valid (since Xtend 2.2):

package xtend.tutorial.basics

class Xtend01_HelloWorld {

static String separator2 = java::io::File::separator

}

Note that type inference is currently not supported for field declarations thus you'll have to specify the type explicitly.

Regards,
Sebastian

Thanks for the working code and explanation.

I'm looking forward to bug 367885 being fixed so fields can be both
static and final.
