PackedDataContainerRef
======================

**Inherits:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

An internal class used by :ref:`PackedDataContainer<class_PackedDataContainer>` to pack nested arrays and dictionaries.

.. rst-class:: classref-introduction-group

Description
-----------

When packing nested containers using :ref:`PackedDataContainer<class_PackedDataContainer>`, they are recursively packed into **PackedDataContainerRef** (only applies to :ref:`Array<class_Array>` and :ref:`Dictionary<class_Dictionary>`). Their data can be retrieved the same way as from :ref:`PackedDataContainer<class_PackedDataContainer>`.

::

    var packed = PackedDataContainer.new()
    packed.pack([1, 2, 3, ["abc", "def"], 4, 5, 6])
    
    for element in packed:
        if element is PackedDataContainerRef:
            for subelement in element:
                print("::", subelement)
        else:
            print(element)
    
    # Prints:
    # 1
    # 2
    # 3
    # ::abc
    # ::def
    # 4
    # 5
    # 6

Method Descriptions
-------------------

.. _class_PackedDataContainerRef_method_size:

.. rst-class:: classref-method

:ref:`int<class_int>` **size** **(** **)** |const|

Returns the size of the packed container (see :ref:`Array.size<class_Array_method_size>` and :ref:`Dictionary.size<class_Dictionary_method_size>`).

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |constructor| replace:: :abbr:`constructor (This method is used to construct a type.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
.. |operator| replace:: :abbr:`operator (This method describes a valid operator to use with this type as left-hand operand.)`
.. |bitfield| replace:: :abbr:`BitField (This value is an integer composed as a bitmask of the following flags.)`
