Method Details

getName

@NonNull
public @NonNull String getName()

Description copied from interface: Feature

The name of the feature. It must be unique.

Specified by:

getName in interface Feature

Specified by:

getName in interface io.micronaut.core.naming.Named

Returns:

the name of the feature

getTitle

public String getTitle()

Specified by:

getTitle in interface Feature

Returns:

The title of the feature

getDescription

public String getDescription()

Specified by:

getDescription in interface io.micronaut.core.naming.Described

Specified by:

getDescription in interface Feature

processSelectedFeatures

public void processSelectedFeatures(FeatureContext featureContext)

Description copied from interface: Feature

If this method is called for a given feature then that feature was explicitly selected or was included by default as a result of DefaultFeature.shouldApply(io.micronaut.starter.options.Options, java.util.Set). This method can be implemented to allow features to modify the list of features that will apply to the project. The methods FeatureContext.addFeature(Feature) and FeatureContext.exclude(FeaturePredicate) are the primary ways to add and remove features from the context. FeatureContext.isPresent(Class) can be used to determine the existence of other features in order to make decisions.

Specified by:

processSelectedFeatures in interface Feature

Overrides:

processSelectedFeatures in class EaseTestingFeature

Parameters:

featureContext - The feature context

apply

public void apply(GeneratorContext generatorContext)

Description copied from interface: Feature

If this method is called for a given feature that means the feature was explicitly selected, included by default as a result of DefaultFeature.shouldApply(io.micronaut.starter.options.Options, java.util.Set), or added explicitly by another feature through FeatureContext.addFeature(Feature). At this point the feature list is set and cannot change.

Specified by:

apply in interface Feature

Specified by:

apply in interface OpenRewriteFeature

Parameters:

generatorContext - THe generator context

getRecipes

public List<String> getRecipes(GeneratorContext generatorContext)

Specified by:

getRecipes in interface OpenRewriteFeature
