Packed DXF Tags
---------------
Store DXF tags in compact data structures as ``list`` or :class:`array.array` to reduce memory usage.
.. class:: TagList(data: Iterable = None)
Store data in a standard Python ``list``.
Args:
data: iterable of DXF tag values.
.. attribute:: values
Data storage as ``list``.
.. automethod:: clone() -> TagList
.. automethod:: from_tags(tags: Tags, code: int) -> TagList
.. automethod:: clear
.. class:: TagArray(data: Iterable = None)
:class:`TagArray` is a subclass of :class:`TagList`, which store data in an :class:`array.array`.
Array type is defined by class variable ``DTYPE``.
Args:
data: iterable of DXF tag values.
.. attribute:: DTYPE
:class:`array.array` type as string
.. attribute:: values
Data storage as :class:`array.array`
.. automethod:: set_values
.. class:: VertexArray(data: Iterable = None)
Store vertices in an ``array.array('d')``.
Vertex size is defined by class variable :attr:`VERTEX_SIZE`.
Args:
data: iterable of vertex values as linear list e.g. :code:`[x1, y1, x2, y2, x3, y3, ...]`.
.. attribute:: VERTEX_SIZE
Size of vertex (2 or 3 axis).
