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()

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.

Overrides:
getClassName in class ScriptableObject





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.

Overrides:
has in class ScriptableObject

Following copied from class: org.mozilla.javascript.ScriptableObject

Parameters:
name - the name of the property
start - the object in which the lookup began
Returns:
true if and only if the property was found in the object





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.

Overrides:
get in class ScriptableObject

Following copied from class: org.mozilla.javascript.ScriptableObject

Parameters:
name - the name of the property
start - the object in which the lookup began
Returns:
the value of the property (may be null), or NOT_FOUND





importPackage
public void importPackage(Context cx,
                          Scriptable thisObj,
                          java.lang.Object[] args,
                          Function funObj)
