028 * For API internal use only. The cache2k implementation provides the
029 * concrete implementations via this interface. Only one active cache2k
030 * implementation is supported by the API.
031 *
032 * <p>Right now, there is only one implementation within the core package.
033 * Maybe there will be stripped or extended implementations, or special
034 * build implementations, e.g. for Android in the future.
035 *
036 * <p>This is for internal use by the API to locate the implementation.
037 * Do not use or rely on this.
