Class NativeJavaTopPackage

Implemented Interfaces:
Callable, DebuggableObject, Function, IdFunctionCall, Scriptable, Serializable

public class NativeJavaTopPackage
extends NativeJavaPackage
implements Function, IdFunctionCall

This class reflects Java packages into the JavaScript environment. We lazily reflect classes and subpackages, and use a caching/sharing system to ensure that members reflected into one JavaPackage appear in all other references to the same package (as with Packages.java.lang and java.lang).

Method Details

call

public Object call(Context cx,
                   Scriptable scope,
                   Scriptable thisObj,
                   Object[] args)
Call the function. Note that the array of arguments is not guaranteed to have length greater than 0.
Specified by:
call in interface Function
call in interface Callable
Parameters:
cx - the current Context for this thread
scope - the scope to execute the function relative to. This is set to the value returned by getParentScope() except when the function is called from a closure.
thisObj - the JavaScript this object
args - the array of arguments
Returns:
the result of the call

construct

public Scriptable construct(Context cx,
                            Scriptable scope,
                            Object[] args)
Call the function as a constructor. This method is invoked by the runtime in order to satisfy a use of the JavaScript new operator. This method is expected to create a new object and return it.
Specified by:
construct in interface Function
Parameters:
cx - the current Context for this thread
scope - an enclosing scope of the caller except when the function is called from a closure.
args - the array of arguments
Returns:
the allocated object

execIdCall

public Object execIdCall(IdFunctionObject f,
                         Context cx,
                         Scriptable scope,
                         Scriptable thisObj,
                         Object[] args)
'thisObj' will be null if invoked as constructor, in which case instance of Scriptable should be returned
Specified by:
execIdCall in interface IdFunctionCall

init

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