public class AbstractServiceAttribute
implements ServiceAttributeInterface

Service attribute describing some additional criteria that may be used to distinguish services that implement the same service type(s) as specified by Java classes. Zero or more service attributes may be associated with a service that is to be accessible in the context of the Discovery service.

Each service is free to determine whether or not it wants to define attributes to qualify its lookup via the Discovery service. If such filtering is desired then the service implementor must define one or more classes that extend this AbstractServiceAttribute class subject to the following considerations:

• distinguished by the implementation of the ServiceAttributeInterface interface, which is used purely as a type identifier
• must have a default (no argument) constructor.
• no methods are allowed
• each field of the object must be a public object reference
• instance variables of primitive types are not permitted
• instance variable references to object types that are static, transient, final, or not public are ignored
