Class NativeJavaClass

Implemented Interfaces:
Callable, Function, Scriptable, Serializable, Wrapper
public class NativeJavaClass
extends NativeJavaObject
implements Function
This class reflects Java classes into the JavaScript environment, mainly for constructors and static members. We lazily reflect properties, and currently do not guarantee that a single j.l.Class is only reflected once into the JS environment, although we should. The only known case where multiple reflections are possible occurs when a j.l.Class is wrapped as part of a method return or property access, rather than by walking the Packages/java tree.

Method Details

call

public Object call(Context cx,
                   Scriptable scope,
                   Scriptable thisObj,
                   Object[] args)
Specified by:
call in interface Function
call in interface Callable

construct

public Scriptable construct(Context cx,
                            Scriptable scope,
                            Object[] args)
Specified by:
construct in interface Function

get

public Object get(String name,
                  Scriptable start)
Specified by:
get in interface Scriptable
Overrides:
get in interface NativeJavaObject

getClassName

public String getClassName()
Specified by:
getClassName in interface Scriptable
Overrides:
getClassName in interface NativeJavaObject

getClassObject

public Class getClassObject()

getDefaultValue

public Object getDefaultValue(Class hint)
Specified by:
getDefaultValue in interface Scriptable
Overrides:
getDefaultValue in interface NativeJavaObject

getIds

public Object[] getIds()
Specified by:
getIds in interface Scriptable
Overrides:
getIds in interface NativeJavaObject

has

public boolean has(String name,
                   Scriptable start)
Specified by:
has in interface Scriptable
Overrides:
has in interface NativeJavaObject

hasInstance

public boolean hasInstance(Scriptable value)
Determines if prototype is a wrapped Java object and performs a Java "instanceof". Exception: if value is an instance of NativeJavaClass, it isn't considered an instance of the Java class; this forestalls any name conflicts between java.lang.Class's methods and the static methods exposed by a JavaNativeClass.
Specified by:
hasInstance in interface Scriptable
Overrides:
hasInstance in interface NativeJavaObject

initMembers

protected void initMembers()
Overrides:
initMembers in interface NativeJavaObject

put

public void put(String name,
                Scriptable start,
                Object value)
Specified by:
put in interface Scriptable
Overrides:
put in interface NativeJavaObject

toString

public String toString()
