Class AnyService

java.lang.Object
org.osgi.service.component.AnyService
public final class AnyService extends Object
A marker type whose name is used in the interface attribute of a reference element in a component description to indicate that the type of the service for a reference is not specified and can thus be any service type.

When specifying this marker type in the interface attribute of a reference element in a component description:

  • The service type of the reference member or parameter must be java.lang.Object so that any service object can be provided.
  • The target attribute of the reference element must be specified to constrain the target services.

For example: 

 @Reference(service = AnyService.class, target = "(osgi.jakartars.extension=true)")
 List<Object> extensions;
