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

UnmaskedArray implements an 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 with mask=None.

It is also like Apache Arrow’s 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__:

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])
