Examples of AssociationManagement

org.rioproject.associations.AssociationManagement
AssociationManagement provides the necessary support to manage Associations a ServiceBean has to other services. Associations provide a mechanism to model and enforce uses and requires associations between services in an OperationalString. Associations are optional and may be declared as part of a ServiceBean element's specification. Associations take 2 forms:
- Uses
  A weak association relationship where if A uses B exists then, then B may be present for A
- Requires
  A stronger association relationship where if A requires B exists then B must be present for A
- Colocated
  An association which requires that A be colocated with B in the same JVM. If B does not exist, or cannot be located, A shall not be created without B
- Opposed
  An association which requires that A exist in a different JVM then B.
- Isolated
  An association which requires that A exist in a different machine then B.
Associations are created during the design/modelling phase and enforced during runtime The AssociationManager will discover and monitor services described in each Association. An Association will either be discovered, changed or broken. Each state transition an Association goes through will result in the notification of any AssociationListener objects which have registered to this AssociationManagement instance. If the Association is of type AssociationType.REQUIRES and the Association state becomes Association.BROKEN and there are no services that match the Association type that have a state of Association.DISCOVERED, then the AssociationManagement object will unadvertise the ServiceBean using the provided ServiceBeanControl interface. Conversely, if the Association is of type AssociationType.REQUIRES and a service is discovered which matches the service type(s), then the Association state becomes Association.DISCOVERED. If the ServiceBean is not advertised, the AssociationManager will advertise the ServiceBean @author Dennis Reedy
