Appendix E      Stability of MQ Interfaces

Sun™ ONE Message Queue (MQ) uses many interfaces, that might be of use to administrators for automating administration tasks. Table E-1 classifies these interfaces according to how stable they are, that is, how unlikely they are to change in subsequent versions of the product. The classification scheme is described in Table E-2.

Table E-2    Interface Stability Classification Scheme 

Classification	Description
Private	Not for direct use by customers. May change or be removed in any release.
Evolving	For use by customers. Subject to incompatible change at a major (e.g. 3.0, 4.0) or minor (e.g. 3.1, 3.2) release. The changes will be made carefully and slowly. Reasonable efforts will be made to ensure that all changes are compatible but that is not guaranteed.
Stable	For use by customers. Subject to incompatible change at a major (e.g 3.0, 4.0) release only.
Standard	For use by customers. These interfaces are defined by a formal standard, and controlled by a standards organization. Incompatible changes to these interfaces are rare.
Unstable	For use by customers. Subject to incompatible change at a major (e.g. 3.0, 4.0) or minor (e.g. 3.1, 3.2) release. Customers are advised that these interfaces may be removed or changed substantially and in an incompatible way in a future release. It is recommended to customer to not create explicit dependencies on unstable interfaces.
