.. py:module: ak.contents.UnmaskedArray

Defined in `awkward.contents.unmaskedarray <https://github.com/scikit-hep/awkward/blob/e9dd2694cf5c6ccb1717358fe926816d8ecbfb9c/src/awkward/contents/unmaskedarray.py>`__ on `line 55 <https://github.com/scikit-hep/awkward/blob/e9dd2694cf5c6ccb1717358fe926816d8ecbfb9c/src/awkward/contents/unmaskedarray.py#L55>`__.

.. py:class:: ak.contents.UnmaskedArray(self, content, *, parameters=None)

UnmaskedArray implements an :py:obj:`ak.types.OptionType` for which the values are
never, in fact, missing. It exists to satisfy systems that formally require this
high-level type without the overhead of generating an array of all True or all
False values.

This is like NumPy's
`masked arrays <https://docs.scipy.org/doc/numpy/reference/maskedarray.html>`__
with ``mask=None``.

It is also like Apache Arrow's
`validity bitmaps <https://arrow.apache.org/docs/format/Columnar.html#validity-bitmaps>`__
because the bitmap can be omitted when all values are valid.

To illustrate how the constructor arguments are interpreted, the following is a
simplified implementation of ``__init__``, ``__len__``, and ``__getitem__``:

.. code-block:: python


    class UnmaskedArray(Content):
        def __init__(self, content):
            assert isinstance(content, Content)
            self.content = content

        def __len__(self):
            return len(self.content)

        def __getitem__(self, where):
            if isinstance(where, int):
                return self.content[where]
            else:
                return UnmaskedArray(self.content[where])
