## com.sas.services.discovery
Interface ServiceDiscoveryConfigurationInterface

All Superinterfaces:
  java.io.Serializable

All Known Implementing Classes:
  ServiceDiscoveryConfiguration

    public interface ServiceDiscoveryConfigurationInterface

extends java.io.Serializable

Interface describing a service discovery configuration consisting of

- an ID used to uniquely identify a service across JVMs and
- optional service attributes which may be used to qualify a discovery lookup to distinguish among multiple services that satisfy the same service types.

Each discoverable service will be associated with a unique ID. This ID may be used by a client to re-acquire a previously discovered service from the Discovery service.

While services are primarily looked up based upon the service types they implement, service attributes may optionally be associated to provide additional filtering criteria. Optional service attributes are specified as part of a service's `com.sas.services.discovery.ServiceDiscoveryConfiguration`. If a service has a service discovery configuration it will be accessible as follows:

     String serviceDiscoveryId = null;
     final ServiceConfigurationInterface serviceConfig =
        service.getServiceConfiguration();
     if (serviceConfig != null) {
        final ServiceDiscoveryConfigurationInterface serviceDiscoveryConfig =
        serviceConfig.getServiceConfiguration(
           ServiceConfigurationInterface.CONFIGURATION_SERVICE_DISCOVERY);
        if ((serviceDiscoveryConfig != null) &&
            (serviceDiscoveryConfig instanceof
             ServiceDiscoveryConfigurationInterface)) {
           serviceDiscoveryId = ((ServiceDiscoveryConfigurationInterface)
              serviceDiscoveryConfig).getDiscoveryId();
        }
    }

    ID used to represent a service as a deployable component in a repository.

### isDelegateRegistrationEnabled

    boolean isDelegateRegistrationEnabled()

  Determines whether or not the service should be registered with discovery delegates.

  Returns:
    `true` if registration is enabled or `false` if it isn't.

### setDelegateRegistrationEnabled

    void setDelegateRegistrationEnabled(boolean isDelegateRegistrationEnabled)

  Sets the service discovery registration policy.

  Parameters:
    `isDelegateRegistrationEnabled` - `true` if the service is to be registered with discovery delegates or `false` if it isn't.

### getServiceTypes

    java.lang.Class[] getServiceTypes()

  Gets the service types supported by the service. These represent the Java classes the service is, extends, or implements.

  Returns:
    Service types supported by the service.

### setServiceTypes

    void setServiceTypes(java.lang.Class[] serviceTypes)
                         throws ServiceException

  Sets service types that a service is, extends, or implements. A service must specify 1..* service types.

  Parameters:
    `serviceTypes` - Service types supported by the service.
  Throws:
    `ServiceException` - if no service types are specified.

### getServiceAttributes

    ServiceAttributeInterface[] getServiceAttributes()

  Gets optional attributes that may be provided to specify additional lookup criteria about a service. These provide the capability to provide some level of filtering among services which satisfy the same service types.

  Returns:
    Service attributes or `null` if no attributes are associated with this service.

### setServiceAttributes

    void setServiceAttributes(ServiceAttributeInterface[] serviceAttributes)

  Sets optional attributes that may be provided to specify additional lookup criteria about a service. These provide the capability to provide some level of filtering among services which satisfy the same service types.
