CompositeTransform

class utilipy.data_utils.xfm.CompositeTransform(transforms: Sequence, fromtype, totype, priority: int = 1, register_graph=None)

Bases: utilipy.data_utils.xfm.transformations.DataTransformBase

A transformation from a series of single-step transformations.

Todo

• support passed arguments to steps within the transform list

Parameters

transformssequence of DataTransform objects

The sequence of transformations to apply.

fromtypeclass

The coordinate frame class to start from.

totypeclass

The coordinate frame class to transform into.

prioritynumber

The priority if this transform when finding the shortest coordinate transform path - large numbers are lower priorities.

register_graphTransformGraph or None

A graph to register this transformation with on creation, or None to leave it unregistered.

Create Composite Data Transformer.

Methods Summary

__call__(fromdata, *args[, _override_kws])

Run transformation.

Methods Documentation

__call__(fromdata, *args, _override_kws: bool = False, **kwargs)

Run transformation.

Parameters

fromdataAny

*argsAny

arguments into the first transformation

_override_kwsbool

whether to permit the default kwargs in the first transformation, or completely override by any supplied kwargs (if any are given here). If they are permitted, individual arguments are still overriden by ones supplied here.

**kwargsAny

keyword argument into the first transformation

Returns

todataAny

The result of running fromdata through the transformation series listed in self.transforms
