tspy.data_structures.io.TimeSeriesWriter module

class tspy.data_structures.io.TimeSeriesWriter.TimeSeriesWriter(tsc, j_time_series_writer)

Bases: object

Builder pattern used for writing a time-series to an outside data-source

Notes

A time-series-writer has a few components:

• observations: the in-memory observations to write to an outside data-source

• options: key-value string pair in map of options to be used in writing

• value-encoder: function to encode a value to a String, by default __str__ is used

This class works as follows:

• builds a blank time-series-writer that only contains observations

• set options and value-encoder (optional)

• save to data-source (using a time-series-write-format) given options and value-encoder

Methods

csv(path)	save as csv
encode_value(value_encoder)	set function to encode a value to a string when writing
object_file(path)	save as object-file
option(key, value)	set an option for this time-series-writer
options(**kwargs)	set multiple options for this time-series-writer
save(time_series_write_format)	save to a user-defined time-series-write-format
