      Adds information about provider services into HashMap.

    • isEmpty

      public static boolean isEmpty()
      Returns true if services contain any provider information.

    • getService

      public static Provider.Service getService​(String key)
      Looks up the requested service by type and algorithm. The service key should be provided in the same format used when registering a service with a provider, for example, "KeyFactory.RSA". Callers can cache the returned service information but such caches should be validated against the result of Service.getCacheVersion() before use.

    • getSecureRandomService

      public static Provider.Service getSecureRandomService()
      Returns the default SecureRandom service description.

    • setNeedRefresh

      public static void setNeedRefresh()
      In addition to being used here when the list of providers changes, this method is also used by the Provider implementation to indicate that a provides list of services has changed.

    • getCacheVersion

      public static int getCacheVersion()
      Returns the current cache version. This has the possible side effect of updating the cache if needed.
