pasteur.extras.transformers.DateTransformer

class pasteur.extras.transformers.DateTransformer(span='year', nullable=False, bins=64, max_len=63, **_)

Attributes

deterministic	For a given output, the input is the same.
lossless	The decoded output equals the input.
name
stateful	Transformer fits variables.

Methods

fit(data[, ref])	Fits to the provided data
fit_transform(data[, ref])	rtype: DataFrame
get_attributes()	rtype: Mapping[str | tuple[str], Attribute]
get_factory(*args, **kwargs)	Returns a factory that registers this module to the system.
iso_to_gregorian(iso_year, iso_week, iso_day)	Gregorian calendar date for the given ISO year, week and day
iso_year_start(iso_year)	The gregorian calendar date of the first day of the given ISO year
reduce(other)
reverse(data[, ref])	When reversing, the data column contains encoded data, whereas the ref column contains decoded/original data.
transform(data[, ref])	rtype: DataFrame

deterministic = True

For a given output, the input is the same.

fit(data, ref=None)

Fits to the provided data

fit_transform(data, ref=None)

Return type:

DataFrame

get_attributes()

Return type:

Mapping[str | tuple[str], Attribute]

classmethod get_factory(*args, **kwargs)

Returns a factory that registers this module to the system.

Any *args and **kwargs passed to this function will be saved and passed to the module’s __init__() method when calling build().

static iso_to_gregorian(iso_year, iso_week, iso_day)

Gregorian calendar date for the given ISO year, week and day

static iso_year_start(iso_year)

The gregorian calendar date of the first day of the given ISO year

lossless = True

The decoded output equals the input.

name: str = 'date'

reduce(other)

reverse(data, ref=None)

When reversing, the data column contains encoded data, whereas the ref column contains decoded/original data. Therefore, the referred columns have to be decoded first.

Return type:

Series

stateful = True

Transformer fits variables.

transform(data, ref=None)

Return type:

DataFrame
