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();
    }
}

Method Detail

getDiscoveryId

java.lang.String getDiscoveryId()

Gets an ID associated with a service that's registered with the discovery service.

Returns:

ID that may be used to lookup a service.

getRepositoryId

java.lang.String getRepositoryId()

Gets the ID associated with the repository instance of a metadata ServiceComponent element.

Returns:

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.

Parameters:

serviceAttributes - Service attributes or null if no attributes are associated with this service.

addServiceAttribute

boolean addServiceAttribute(ServiceAttributeInterface serviceAttribute)

Adds a service lookup attribute. A service may optionally designate attributes which can be used to distinguish itself from other services satisfying the same service interfaces. A client would then use the DiscoveryService to lookup a service satisfying particular service interface(s) and optionally designated service attributes.

Parameters:

serviceAttribute - Service lookup attribute.

Returns:

true if the service lookup attribute was added or false if it wasn't.

addServiceAttributes

void addServiceAttributes(java.util.List serviceAttributes)

Adds service lookup attributes. A service may optionally designate attributes which can be used to distinguish itself from other services satisfying the same service interfaces. A client would then use the DiscoveryService to lookup a service satisfying particular service interface(s) and optionally designated service attributes.

Parameters:

serviceAttributes - List of ServiceAttributeInterface.

removeServiceAttribute

boolean removeServiceAttribute(ServiceAttributeInterface serviceAttribute)

Removes a service lookup attribute.

Parameters:

serviceAttribute - Service lookup attribute to be removed.

Returns:

true if the service lookup attribute was removed or false if it wasn't.

getServiceFactory

java.lang.String getServiceFactory()

Gets the fully qualified name of the Java class that serves as the services factory. Note that this factory must implement ServiceFactoryInterface.

Returns:

Fully qualified Java name of a class that serves as a service's factory. This class must implement ServiceFactoryInterface.

setServiceFactory

void setServiceFactory(java.lang.String serviceFactory)
                       throws InitializationException

Sets the fully qualified name of the Java class that serves as the services factory. Note that this factory must implement ServiceFactoryInterface.

Parameters:

The ServiceComponent attribute or null if no ServiceComponent attribute is associated with this service.

setServiceGroup

void setServiceGroup(java.lang.String serviceGroup)

Set the name of the service's deployment group.

Parameters:

serviceGroup - The service's deployment group. This corresponds to the name of the Tree that represents service's group.

getServiceGroup

Gets the name of the service's deployment group.

Returns:

The name of the service's deployment group which is represented in metadata as a Tree.

getJVMId
