<brief_description>
An internal class used by [PackedDataContainer] to pack nested arrays and dictionaries.
</brief_description>
<description>
When packing nested containers using [PackedDataContainer], they are recursively packed into [PackedDataContainerRef] (only applies to [Array] and [Dictionary]). Their data can be retrieved the same way as from [PackedDataContainer].
[codeblock]
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
