Accessors

Accessors can be written and registered with Koalas Dataframes, Series, and Index objects. Accessors allow developers to extend the functionality of Koalas objects seamlessly by writing arbitrary classes and methods which are then wrapped in one of the following decorators.

register_dataframe_accessor(name)	Register a custom accessor with a DataFrame
register_series_accessor(name)	Register a custom accessor with a Series object
register_index_accessor(name)	Register a custom accessor with an Index
