public class ImporterTopLevel

extends ScriptableObject

Class ImporterTopLevel This class defines a ScriptableObject that can be instantiated as a top-level ("global") object to provide functionality similar to Java's "import" statement.

This class can be used to create a top-level scope using the following code:

  Scriptable scope = new ImporterTopLevel(cx);
 

Then JavaScript code will have access to the following methods:

• importClass - will "import" a class by making its unqualified name available as a property of the top-level scope
• importPackage - will "import" all the classes of the package by searching for unqualified names as classes qualified by the given package.

The following code from the shell illustrates this use:

 js> importClass(java.io.File)
 js> f = new File('help.txt')
 help.txt
 js> importPackage(java.util)
 js> v = new Vector()
