|
Specialized Cython take which sets NaN values in one pass
|
|
This dispatches to ``take`` defined on ExtensionArrays.
|
|
Note: this function assumes that the indexer is a valid(ated) indexer with
|
no out of bound indices.
|
|
Parameters
|
----------
|
arr : np.ndarray or ExtensionArray
|
Input array.
|
indexer : ndarray
|
1-D array of indices to take, subarrays corresponding to -1 value
|
indices are filed with fill_value
|
axis : int, default 0
|
Axis to take from
|
fill_value : any, default np.nan
|
Fill value to replace -1 values with
|
allow_fill : bool, default True
|
If False, indexer is assumed to contain no -1 values so no filling
|
will be done. This short-circuits computation of a mask. Result is
|
undefined if allow_fill == False and -1 is present in indexer.
|
|
Returns
|
-------
|
subarray : np.ndarray or ExtensionArray
|
May be the same type as the input, or cast to an ndarray.

|
Specialized version for 1D arrays. Differences compared to `take_nd`:
|
|
- Assumes input array has already been converted to numpy array / EA
|
- Assumes indexer is already guaranteed to be intp dtype ndarray
|
- Only works for 1D arrays
|
|
To ensure the lowest possible overhead.
|
|
Note: similarly to `take_nd`, this function assumes that the indexer is
|
a valid(ated) indexer with no out of bound indices.
|
|
Parameters
|
----------
|
arr : np.ndarray or ExtensionArray
|
Input array.
|
indexer : ndarray
|
1-D array of indices to take (validated indices, intp dtype).
|
fill_value : any, default np.nan
|
Fill value to replace -1 values with
|
allow_fill : bool, default True
|
If False, indexer is assumed to contain no -1 values so no filling
|
will be done. This short-circuits computation of a mask. Result is
|
undefined if allow_fill == False and -1 is present in indexer.
|
mask : np.ndarray, optional, default None
|
If `allow_fill` is True, and the mask (where indexer == -1) is already
|
known, it can be passed to avoid recomputation.
