A BidiMap is an extension to the Map. A bidirectional map (BidiMap), also called a hash bag, is an associative data structure in which the key-value pairs form a one-to-one relation. This relation works in both directions by allow the value to also act as a key to key, e.g. a ...
To change the Group-by fields, check the box by the field you want to group by in the bottom-left list view. To change the Order-by fields, select a Group-by field (it must be checked) and click the ">>" button to add it to the Order-by table. To remove a field from the ...
Redis本身是一个Map,其中所有的数据都是采用key:value的形式存储 这里的数据类型主要是指存储的,也即是value的数据类型,key的数据类型永远都是String redis中value使用的数据结构有: String:字符串类型 List:列表类型 Hash:哈希表类型 Set:无序集合类型
