public class ImporterTopLevel
extends org.mozilla.javascript.IdScriptableObject

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: 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()

ImporterTopLevel

public ImporterTopLevel(Context cx,
                        boolean sealed)
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 Scriptable
Specified by:
getClassName in class ScriptableObject

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 Scriptable
Overrides:
has in class org.mozilla.javascript.IdScriptableObject
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

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 Scriptable
Overrides:
get in class org.mozilla.javascript.IdScriptableObject
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

                          Scriptable thisObj,

                          Function funObj)
Deprecated. Kept only for compatibility.


initPrototypeId

protected void initPrototypeId(int id)
Overrides:
