Interface RepositoryFeature<T extends RepositoryFeature<T>>

Type Parameters:

T - the concrete feature implementation.

All Known Implementing Classes:

ArtifactCleanupFeature, IndexCreationFeature, RemoteIndexFeature, StagingRepositoryFeature

public interface RepositoryFeature<T extends RepositoryFeature<T>>

The repository feature holds information about specific features. The may not be available by all repository implementations. Features should be simple objects for storing additional data, the should not implement too much functionality. Additional functionality the uses the information in the feature objects should be implemented in the specific repository provider and repository implementations, or in the repository registry if it is generic. But features may throw events, if it's data is changed. This interface is to get access to a concrete feature by accessing the generic interface.

Method Detail

getId

default String getId()

Unique Identifier of this feature. Each feature implementation has its own unique identifier.

Returns:

the identifier string which should be unique for the implementation class.

isFeature

default boolean isFeature(String featureId)

Tells, if this instance is a feature of the given identifier.

Parameters:

featureId - the feature identifier string to check

Returns:

true, if this instance is a instance with the feature id, otherwise false

isFeature

default <K extends RepositoryFeature<K>> boolean isFeature(Class<K> clazz)

Tells, if the this instance is a feature of the given feature class.

Type Parameters:

K - the concrete feature implementation.

Parameters:

clazz - The class to check against.

Returns:

get

T get()

Returns the concrete feature instance.

Returns:

the feature instance.
