PackedDataContainerRef

继承： RefCounted < Object

An internal class used by PackedDataContainer to pack nested arrays and dictionaries.

描述

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.

    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
