RegionsSelector

class gwcs.selector.RegionsSelector(inputs, outputs, selector, label_mapper, undefined_transform_value=nan, name=None, **kwargs)

Bases: Model

This model defines discontinuous transforms. It maps inputs to their corresponding transforms. It uses an instance of _LabelMapper as a proxy to map inputs to the correct region.

Parameters:

inputslist of str

Names of the inputs.

outputslist of str

Names of the outputs.

selectordict

Mapping of region labels to transforms. Labels can be of type int or str, transforms are of type Model.

label_mappera subclass of _LabelMapper

A model which maps locations to region labels.

undefined_transform_valuefloat, np.nan (default)

Value to be returned if there’s no transform defined for the inputs.

namestr

The name of this transform.
