Examples of org.jredis.RedisException

org.jredis.RedisException
[TODO: update doc regarding "extensions"] RedisExceptions are only created/raised subsequent to an error result from the redis server. These exceptions are _not_ intended as a general purpose exception mechanism for implementations of this specification. Accordingly, this exception (and extensions if any) do not (and must not) provide default no arg constructors. (Minimal information required is an associated {@link Command} object.)
Further, this class (and extension if any) should never expose a constructor accepting an underlying 'cause' (as in {@link Exception#Exception(Throwable)}), since this excpetion, to repeat, has very specific semantics: Redis has responded with an error status to an issued command and the content of that message (e.g. "-ERR operation on wrong type" is what is required for instantiating a {@link RedisException}. @see ClientRuntimeException @author Joubin Houshyar (alphazero@sensesay.net) @version alpha.0, 04/02/09 @since alpha.0
