Hi All, I am a newbie to Xpand. I have created an Extension file

Extensions.ext

List[String] getOutClasses(List[test::Attribute]) :
    JAVA com.test.Utils.getOutClasses(List[test::Attribute]);

and a java class Utils.java with the static method

public static List<String> getOutClasses(List<Attribute> attributes) {
...
}

but the problem is in the extension file I am not sure how to specify the argument in the Extension file for the java call.

JAVA com.test.Utils.getOutClasses(List[test::Attribute]);

if i do this i get an error "mismatched input 'List' expecting ')'".

Any help here is appreciated. Thanking you in advance.

Hi,

have a look at the doc for JAVA Extensions. Thy syntax is:

JAVA com.test.Utils.getOutClasses(java.util.List);

Hi Christian,
I read the documentation but I thought that I need to specify the List along with the specific type, that is where I made my error. Thanks for your help.
