Interface ConfigurationResourceResolver

@ProviderType
public interface ConfigurationResourceResolver

Getting context-aware configuration resources for a given resource context. This is a low-level interface for supporting advanced use cases. If you just want to fetch some configuration parameters ConfigurationResolver is the right place.

Method Summary

Modifier and Type	Method and Description
Collection<String>	getAllContextPaths(Resource resource) Get all context paths for which context-aware configurations could be defined.
String	getContextPath(Resource resource) Get the inner-most context path (deepest path) returned by getAllContextPaths(Resource).
Resource	getResource(Resource resource, String bucketName, String configName) Get a context-aware singleton configuration resource defined by the given configuration name.
Collection<Resource>	getResourceCollection(Resource resource, String bucketName, String configName) Get a collection of context-aware configuration resources defined by the given configuration name.

Method Detail

getResource

@CheckForNull
Resource getResource(@Nonnull
                                   Resource resource,
                                   @Nonnull
                                   String bucketName,
                                   @Nonnull
                                   String configName)

Get a context-aware singleton configuration resource defined by the given configuration name.

Parameters:

resource - Context resource to fetch configuration for

bucketName - Configuration "bucket" name. Each high-level configuration resolver should store it's configuration data grouped in a child resource of the configuration resource. This is what we call a "bucket", and the resource name is specified with this parameter.

configName - Configuration name or relative path.

Returns:

Configuration resource or null.

getResourceCollection

@Nonnull
Collection<Resource> getResourceCollection(@Nonnull
                                                    Resource resource,
                                                    @Nonnull
                                                    String bucketName,
                                                    @Nonnull
                                                    String configName)

Get a collection of context-aware configuration resources defined by the given configuration name.

Parameters:

resource - Context resource to fetch configuration for

bucketName - Configuration "bucket" name. Each high-level configuration resolver should store it's configuration data grouped in a child resource of the configuration resource. This is what we call a "bucket", and the resource name is specified with this parameter.

configName - Configuration name or relative path.

Returns:

Collection of configuration resources, the collection might be empty.

getContextPath

String getContextPath(@Nonnull
                      Resource resource)

Get the inner-most context path (deepest path) returned by getAllContextPaths(Resource).

Parameters:

resource - Context resource to fetch configuration for

Returns:

Context path or null

getAllContextPaths

@Nonnull
Collection<String> getAllContextPaths(@Nonnull
                                               Resource resource)

Get all context paths for which context-aware configurations could be defined. The context paths are always ancestors of the resource path, or the resource path itself. Which ancestors are allowed for context-aware configuration depends on configuration.

Parameters:

resource - Context resource to fetch configuration for

Returns:

List of context paths
