ak.contents.IndexedOptionArray#
Defined in awkward.contents.indexedoptionarray on line 54.
- class ak.contents.IndexedOptionArray(self, index, content, *, parameters=None)#
IndexedOptionArray is an ak.contents.IndexedArray for which
negative values in the index are interpreted as missing. It represents
ak.types.OptionType data like ak.contents.ByteMaskedArray,
ak.contents.BitMaskedArray, and ak.contents.UnmaskedArray, but
the flexibility of the arbitrary index makes it a common output of
many operations.
IndexedOptionArray doesn’t have a direct equivalent in Apache Arrow.
To illustrate how the constructor arguments are interpreted, the following is a
simplified implementation of __init__, __len__, and __getitem__:
class IndexedOptionArray(Content):
def __init__(self, index, content):
assert isinstance(index, (Index32, Index64))
assert isinstance(content, Content)
for x in index:
assert x < len(content) # index[i] may be negative
self.index = index
self.content = content
def __len__(self):
return len(self.index)
def __getitem__(self, where):
if isinstance(where, int):
if where < 0:
where += len(self)
assert 0 <= where < len(self)
if self.index[where] < 0:
return None
else:
return self.content[self.index[where]]
elif isinstance(where, slice) and where.step is None:
return IndexedOptionArray(
self.index[where.start : where.stop], self.content
)
elif isinstance(where, str):
return IndexedOptionArray(self.index, self.content[where])
else:
raise AssertionError(where)
