/**
* This class implements an enumeration whose values may be used to
* indicate the stability level of API classes and/or methods. Code
* which is part of the OpenDS public API should be marked with a
* {@code COMMITTED}, {@code UNCOMMITTED}, {@code VOLAITLE}, or
* {@code OBSOLETE} stability level in order to indicate the relative
* likelihood that the associated interface will be changed in an
* incompatible way in the future.
* <BR><BR>
* Third-party developers are free to create code that introduces
* dependencies on OpenDS APIs that are marked {@code COMMITTED},
* {@code UNCOMMITTED}, or {@code VOLATILE}, with an understanding
* that the less stable an OpenDS API is, the more likely that
* third-party code which relies upon it may need to be altered in
* order to work properly with future versions.
* <BR><BR>
* Changes to the stability level of a class or package should only be
* made between major releases and must be denoted in the release
* notes for all releases with that major version. If a public API
* element that is marked {@code COMMITTED}, {@code UNCOMMITTED}, or
* {@code VOLATILE} is to be made private, it is strongly recommended
* that it first be transitioned to {@code OBSOLETE} before ultimately
* being marked {@code PRIVATE}.
* <BR><BR>
* New packages and classes introduced into the OpenDS code base may
* be assigned any stability level. New methods introduced into
* existing classes that are part of the public API may be created
* with any stability level as long as the introduction of that method
* is compliant with the stability level of the class. If a method
* that is part of the OpenDS public API is not marked with an
* explicit stability level, then it should be assumed that it has the
* same stability level as the class that contains it.
