Examples of org.mozilla.javascript.ImporterTopLevel

org.mozilla.javascript.ImporterTopLevel
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() []

            Scriptable bsf = Context.toObject(new BSFFunctions(mgr, this), global);
