public class ImporterTopLevel extends TopLevel
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:
js> importClass(java.io.File)
js> f = new File('help.txt')
help.txt
js> importPackage(java.util)
js> v = new Vector()
