Examples of org.springframework.data.redis.connection.RedisConnection

org.springframework.data.redis.connection.RedisConnection
A connection to a Redis server. Acts as an common abstraction across various Redis client libraries (or drivers). Additionally performs exception translation between the underlying Redis client library and Spring DAO exceptions. The methods follow as much as possible the Redis names and conventions. @author Costin Leau
