call
public java.lang.Object call(Context cx,
                             Scriptable scope,
                             Scriptable thisObj,
                             java.lang.Object[] args)
                      throws JavaScriptException
- Call the function.
 Note that the array of arguments is not guaranteed to have
 length greater than 0.- 
- Specified by: 
- callin 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- thisobject
- args- the array of arguments
- Returns:
- the result of the call
- Throws:
- JavaScriptException- if an uncaught exception
            occurred while executing the function
 
construct
public Scriptable construct(Context cx,
                            Scriptable scope,
                            java.lang.Object[] args)
                     throws JavaScriptException

 This method is invoked by the runtime in order to satisfy a use
 of the JavaScript newoperator.  This method is
 expected to create a new object and return it.
