Method Details

getName

public 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

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(ApplicationType, 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. This method can be implemented to modify the generated project. The feature can add templates by executing GeneratorContext.addTemplate(String, io.micronaut.starter.template.Template), modify configuration by modifying GeneratorContext.getConfiguration() or GeneratorContext.getBootstrapConfiguration(), or modify build properties through GeneratorContext.getBuildProperties().

Specified by:

apply in interface Feature

Parameters:

generatorContext - THe generator context

shouldApply

public boolean shouldApply(ApplicationType applicationType,
 Options options,
 Set<Feature> selectedFeatures)

Description copied from interface: DefaultFeature

Determines if the feature should be applied to the project. Default features do not need to be concerned if the feature was already selected and therefore is already in the list of selected features. The addition to the set is based on the identity of the feature instance and all features are singletons.

Specified by:

shouldApply in interface DefaultFeature

Parameters:

applicationType - The application type

options - The options

selectedFeatures - The features manually selected by the user

Returns:

True if the feature should apply

getMicronautDocumentation

public String getMicronautDocumentation()

Specified by:

getMicronautDocumentation in interface Feature

Returns:

Returns a link to Micronaut documentation about the feature. eg. https://micronaut-projects.github.io/micronaut-cache/latest/guide/index.html#hazelcast

testContainersArtifactId

public String testContainersArtifactId()

Specified by:

testContainersArtifactId in interface ContributingTestContainerArtifactId
