    public class ImporterTopLevel

extends TopLevel

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> importPackage(java.util)
     js> v = new Vector()

    Method Detail

    getClassName

    public java.lang.String getClassName()

    Description copied from class: ScriptableObject
    Return the name of the class.

     This is typically the same name as the constructor.
     Classes extending ScriptableObject must implement this abstract
     method.

    Specified by:getClassName in interface ScriptableOverrides:getClassName in class TopLevel

    init

    public static void init(Context cx,
                            Scriptable scope,
                            boolean sealed)

    initStandardObjects

    public void initStandardObjects(Context cx,
                                    boolean sealed)

    has

    public boolean has(java.lang.String name,
                       Scriptable start)

    Description copied from class: ScriptableObject
    Returns true if the named property is defined.

    Specified by:has in interface ScriptableOverrides:has in class IdScriptableObject

    Parameters:name - the name of the propertystart - the object in which the lookup began
    Returns:true if and only if the property was found in the objectSee Also:Scriptable.get(String, Scriptable),
    ScriptableObject.getProperty(Scriptable, String)

    get

    public java.lang.Object get(java.lang.String name,
                                Scriptable start)

    Description copied from class: ScriptableObject
    Returns the value of the named property or NOT_FOUND.

     If the property was created using defineProperty, the
     appropriate getter method is called.

    Specified by:get in interface ScriptableOverrides:get in class IdScriptableObject

    Parameters:name - the name of the propertystart - the object in which the lookup began
    Returns:the value of the property (may be null), or NOT_FOUNDSee Also:Context.getUndefinedValue()
