OptionsStep

interface OptionsStep<T, R>
Deprecated: Use FeatureExtractorBuilder.OptionsStep from atrium-logic; will be removed with 1.0.0

Step which allows to override previously defined properties -- such as use a different description -- but also allows to define options where usually a default value is used, such as use the subject itself as representation.

Parameters

T - the type of the subject.

Properties

featureExtraction	`abstract val featureExtraction: (T) -> Option<R>` The previously specified feature extraction lambda.
featureExtractionStep	`abstract val featureExtractionStep: FeatureExtractorBuilder.FeatureExtractionStep<T>` The so far chosen options up to the FeatureExtractionStep step.

Functions

withOptions

open fun withOptions(configuration: FeatureExtractorBuilder.OptionsChooser<R>.() -> Unit): FeatureExtractorBuilder.FinalStep<T, R>

Allows to define the FeatureOptions via an OptionsChooser-lambda which provides convenience functions.

abstract fun withOptions(expectOptions: FeatureOptions<R>): FeatureExtractorBuilder.FinalStep<T, R>

Uses the given expectOptions.

withoutOptions

abstract fun withoutOptions(): FeatureExtractorBuilder.FinalStep<T, R>

States explicitly that no optional FeatureOptions are defined, which means, build will create a new Expect based on the previously defined mandatory options but without any optional options or in other words, the default values are used for the optional options.
