apache_beam.transforms.sideinputs module

Internal side input transforms and implementations.

For internal use only; no backwards-compatibility guarantees.

Important: this module is an implementation detail and should not be used directly by pipeline writers. Instead, users should use the helper methods AsSingleton, AsIter, AsList and AsDict in apache_beam.pvalue.

class apache_beam.transforms.sideinputs.SideInputMap(view_class, view_options, iterable)[source]

Bases: future.types.newobject.newobject
