Scala-检查是否导入了一个类

Question

In Scala console the command:

import testPackage._

will give the below output:

scala> import testPackage._
import testPackage._

But after importing how to check what are the classes imported in the console or how to list the classes (of testPackage) in the console (just for verification). Please help.

Answer 1

Within the REPL I'm not sure if there's a command for listing all imported classes, however what you can do is use the tabbed completion, just type in:

scala> val tmp : testPackage.

and then hit TAB. You should get a list of the types available within that scope.
