Examples of redis.clients.jedis.Jedis.del()

redis.clients.jedis.Jedis.del()
Remove the specified keys. If a given key does not exist no operation is performed for this key. The command returns the number of keys removed. Time complexity: O(1) @param keys @return Integer reply, specifically: an integer greater than 0 if one ormore keys were removed 0 if none of the specified key existed
