键值对

2.Map集合：一次存入一对元素，以键值对（Key,Value）形式存在，必须保证键的唯一性。键值对, 键唯一, 可以根据键获得值 …

值组

以值组 (key, value) 的串列型别传回辞典集中所有元素。dict.keys()传回辞典集 dict 的所有键值。

例句：

An update to a key column operates like a delete of the old key value followed by an insert of the new key value .

对键列进行更新与删除旧键值然后插入新键值作用相同。

It behaves as though it were a giant hash table , looking up key = value pairs . Give it a key , and set or get some arbitrary data .

Memcached 的奇妙之处在于它的两阶段 hash 的方法，它通过一个巨大的 hash 表来查找 key=value 对，给它一个 key ，就可以 set 或 get 数据了。

Note that this assumes that key columns are never updated ; once a row exists , it is immutably tied to its primary-key value .

注意，这假设从不更新键列；一旦一行存在了，它的主键值就不变了。

Information aggregation is the key value that this part of the workshop brings to the overall development of the customer 's portal .

信息汇总是研讨会的这一部分向整个客户的门户开发提供的主要价值。

Determine in which partition a row with a particular partition key value resides, or where it would be inserted .

确定包含特定分区键值的行位于哪个分区中或将该行插入哪里。

The key technology there came out of our key-value storage technology at HP Labs .

这是一个出自惠普实验室的具有核心价值的存储技术。

From the internal queue , Process Server can process those messages with multiple threads as long as they do not share the same key value .

由于这些消息不共享同一个键值，ProcessServer 可以用多重线程从这个内部队列处理这些消息。

Other key -value pairs can be specified as well, and the JMX API includes facilities for wildcard matching of object names .

也可以指定其他键 -值对，而且 JMXAPI 还包含进行对象名称通配匹配的工具。

Determines what action will happen to the child row or column when a primary key value is changed or deleted .

确定当主键值被更改或删除时将对子行或子列执行的操作。

A key value for the point E5 is calculated from the values at the normally and diagonally disposed boundary points .

根据沿对角线方向和水平竖直方向配置的各边界点的数值，计算出 E5 的控制值。

In the canonical model , a map function processes key-value pairs , resulting in an intermediate set of key-value pairs.

在规范模型中，map 函数处理键值对，这将得出键值对的中间集。

Each section, in turn, has a header line and a list of (key -value ) pairs to set options for each module .

每个小节包含标题行和模块的选项（键 -值对）列表。

Occurs when a key value exists in a partition but does not exist in the corresponding dimension .

当键值存在于分区中，但不存在于相应的维度中时发生。

You can then attach objects that are to be imported for template use to the context using the put (key, value) method of the context .

然后可以使用上下文的 put （key，value ）方法，把将要导入供模板使用的对象附加到上下文中。

The key value can be one of the following : an attribute, a child element, or the content of the matched element .

键值可以是下列任一值：属性、子元素或匹配元素的内容。

Just think of the Preferences object as one big key -value hashtable that structures the keys in a tree -like structure .

只要把 Preferences 对象当作一个大的键 —值散列表（这个表把树形结构中的键组织起来）。

You see the header configuration, composed of key -value pairs that dictate the configuration of the individual request .

可以看到头配置由表示每个请求的配置的键 -值对组成。

When you delete an entire record, you remove all of the data in each field as well as the key value that makes the record unique .

当删除整条记录时，您将删除每个字段中的所有数据以及使该记录唯一的键值。

A unique index is one in which no two rows are permitted to have the same index key value .

唯一索引不允许两行具有相同的索引键值。

Consider a case where an existing row in a DataSet is an Unchanged row with a primary key value of 1 .

请考虑以下示例：DataSet 中的现有行是主键值为 1 的 Unchanged 行。

Recall that this script simply tokenizes the input to key -value pairs , where each value will be 1 (non-unique input ).

回想此脚本简单地将输入标记到键值对，此处每个值都将是 1 （非惟一输入）。
