Examples of org.jredis.ProviderException

org.jredis.ProviderException
Used by JRedis implementation providers to indicate an exception related to the implementation of the specification. Effectively, this exception and its extensions should only be thrown when a fault has occurred that is neither a {@link SystemException}, nor a Redis prompted server side error. @author Joubin Houshyar (alphazero@sensesay.net) @version alpha.0, 04/02/09 @since alpha.0

      throw new ProviderException("Expecting a ValueResponse here => " + e.getLocalizedMessage(), e);
