xarray.CFTimeIndex

class xarray.CFTimeIndex

Custom Index for working with CF calendars and dates

All elements of a CFTimeIndex must be cftime.datetime objects.

__init__($self, /, *args, **kwargs)

Initialize self. See help(type(self)) for accurate signature.

get_duplicates()
get_indexer(target[, method, limit, tolerance])	Compute indexer and mask for new index given the current index.
get_indexer_for(target, **kwargs)	guaranteed return of an indexer even when non-unique This dispatches to get_indexer or get_indexer_nonunique as appropriate
get_indexer_non_unique(target)	Compute indexer and mask for new index given the current index.
get_level_values(level)	Return an Index of values for requested level, equal to the length of the index.
get_loc(key[, method, tolerance])	Adapted from pandas.tseries.index.DatetimeIndex.get_loc

get_values()	return the underlying data as an ndarray
groupby(values)	Group the index labels by a given array of values.
holds_integer()
identical(other)	Similar to equals, but check that other comparable attributes are also equal
insert(loc, item)	Make new Index inserting new item at location.
intersection(other)	Form the intersection of two Index objects.
is_(other)	More flexible, faster check like is but that works through views

isin(values[, level])	Compute boolean array of whether each index value is found in the passed set of values.
isna()	Detect missing values
isnull()	Detect missing values
item()	return the first element of the underlying data as a python scalar
join(other[, how, level, return_indexers, sort])	this is an internal non-public method
map(mapper)	Apply mapper function to an index.
max()	The maximum value of the object
memory_usage([deep])	Memory usage of my values
min()	The minimum value of the object
notna()	Inverse of isna
notnull()	Inverse of isna
nunique([dropna])	Return number of unique elements in the object.
putmask(mask, value)	return a new Index of the values set with the mask
ravel([order])	return an ndarray of the flattened values of the underlying data
reindex(target[, method, level, limit, …])	Create index with target’s values (move/add/delete values as necessary)
rename(name[, inplace])	Set new names on index.
repeat(repeats, *args, **kwargs)	Repeat elements of an Index.
reshape(*args, **kwargs)	NOT IMPLEMENTED: do not call this method, as reshaping is not supported for Index objects and will raise an error.
searchsorted(value[, side, sorter])	Find indices where elements should be inserted to maintain order.
set_names(names[, level, inplace])	Set new names on index.
set_value(arr, key, value)	Fast lookup of value from 1-dimensional ndarray.

take(indices[, axis, allow_fill, fill_value])	return a new Index of the values selected by the indices
