Interface RestApiExtension

public interface RestApiExtension

Marker interface for registering extensions to the Rest API service.

The REST service provides a RESTful interface to clients that need to manage an OSGi framework through a network connection. Other components running on the same framework can contribute their own specific REST interface and make it available and discoverable by registering this marker service using the Whiteboard pattern.

Integration of third-party REST interfaces with the framework REST service on the implementation level might not always be possible since it requires knowledge about the underlying implementation and an extension mechanism on that level. Specific technologies such as servlets might support this but the REST service could as well be implemented without the use of a supporting abstraction layer and not offer extensibility.

Using this marker service, the REST service includes the advertised service in the Extensions Resource, allowing clients to discover it and use the extension's functionality.

Field Summary

Fields

Modifier and Type	Field and Description
static String	NAME This service property describes the package name of the technology manageable by this REST API extension.
static String	SERVICE This service property refers to the id of the service the REST API extension provides management capabilities for.
static String	URI_PATH This service property describes a URI to the REST extension on this local machine.

Field Detail

URI_PATH

static final String URI_PATH

This service property describes a URI to the REST extension on this local machine. It is either an fully qualified URI with a different port if no integration with the framework REST service is possible or a relative URI implicitly using the same port if integration is possible. The type of this property is java.lang.String and the property is mandatory.

Constant Field Values

NAME

static final String NAME

This service property describes the package name of the technology manageable by this REST API extension. Services specified in OSGi specifications must use their canonical package name as the name. Third-party technologies should also use their package names. The type of this property is java.lang.String and the property is mandatory.

Constant Field Values

SERVICE

static final String SERVICE

This service property refers to the id of the service the REST API extension provides management capabilities for. This can be useful if more than one service of a given type is present in the framework. For example if more than one Http Service is available this property is used to associate a REST extension managing the Http Service with a specific service instance. The type of the property is java.lang.Long and the property is optional; if the REST extension is not directly associated with a service in the service registry, the property should not be set.
