List of hget() Examples

Examples of hget()

redis.clients.jedis.Jedis.hget()
If key holds a hash, retrieve the value associated to the specified field.
If the field is not found or the key does not exist, a special 'nil' value is returned.
Time complexity: O(1) @param key @param field @return Bulk reply
