Class ImporterTopLevel

Implemented Interfaces:
org.mozilla.javascript.debug.DebuggableObject, Scriptable, Serializable
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: 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 Details

get

public Object get(String name,
                  Scriptable start)
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 interface 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

getClassName

public String getClassName()
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
Overrides:
getClassName in interface ScriptableObject

has

public boolean has(String name,
                   Scriptable start)
Returns true if the named property is defined.
Specified by:
has in interface Scriptable
Overrides:
has in interface 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

importPackage

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

initStandardObjects

public void initStandardObjects(Context cx,
                                boolean sealed)
