## Class NativeJavaTopPackage

- java.lang.Object
- - org.mozilla.javascript.ScriptableObject
  - - org.mozilla.javascript.NativeJavaPackage
    - - org.mozilla.javascript.NativeJavaTopPackage

- All Implemented Interfaces:
    java.io.Serializable, Callable, ConstProperties, DebuggableObject, Function, IdFunctionCall, Scriptable, SymbolScriptable

      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 Detail

    - #### call

          public java.lang.Object call(Context cx,
                                       Scriptable scope,
                                       Scriptable thisObj,
                                       java.lang.Object[] args)

      Description copied from interface: `Function`
      Call the function. Note that the array of arguments is not guaranteed to have length greater than 0.
      Specified by:
        `call` in interface `Callable`
      Specified by:
        `call` in interface `Function`
      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,
                                      java.lang.Object[] args)

      Description copied from interface: `Function`
      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

    - #### init

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

    - #### execIdCall

          public java.lang.Object execIdCall(IdFunctionObject f,
                                             Context cx,
                                             Scriptable scope,
                                             Scriptable thisObj,
                                             java.lang.Object[] args)

      Description copied from interface: `IdFunctionCall`
      'thisObj' will be null if invoked as constructor, in which case instance of Scriptable should be returned
      Specified by:
        `execIdCall` in interface `IdFunctionCall`
