通常，调用规则的代码需要确保会话中存在对应于预期键的对象。
It is generally up to the code calling the rule to make sure that the object exists on the session at the expected key.
要这样做，需要确保当XML元素包含子元素时，子元素包含与父代主键相对应的外键。
To do that, we need to make sure that when an XML element can contain a subelement, the subelement contains a foreign key corresponding to the parent's primary key.
集合的键对应于xml元素，键的值对应于xml值。
The Collection's key corresponds to the XML element and the key's value to the XML value.
在这里，e - mail元素被选作键，因为它惟一对应一个联系方式。
Here, the E-mail element is chosen to be the key since it is unique for a contact.
如果键存在，那么便会返回对应的值，或是将其传递给Update委托。
If the key does exist, either the stored value is returned or it is passed to the Update delegate.
我们通过方法对应的键将那些引用注入host对象(我们的Web控制器)。
We're injecting each of those references by their key into the host Object (our web controller).
Compass的配置基于“键—值”的一一对应的设置。
这与在cachespec . xml中指定缓存键不将sessionid作为键的一部分相对应。
This corresponds to specifying the cache key within the cachespec.xml for not having the sessionid as part of the key.
如果它可以表示map上存在某个键，但是有对应的null值，这一点特别重要了。比如清单1中Losangeles键。
This becomes particularly important if it is acceptable for a given key to exist in the map but have a corresponding value of null, as is the case for the Los Angeles key in Listing 1.
location表包含一个外键(region_id)对应region表的主键。
The Location table contains a foreign key (region_id) that corresponds to primary key of the region table.
匹配键是用来识别设备的条件，当规则中所有对应设备的匹配键都被匹配以后，规则会被执行，并且触发动作。
Match keys are conditions used to identify the device which the rule is acting upon.
最后一个最简单了：明显就应该用字典了，这样来把每个键映射到对应的多个值。
The last one is easy: a dictionary is the obvious choice for a mapping from keys to corresponding values.
假如你采用键盘来输入文本，那么每当你按下一个键时，与该键对应的二进制数字代码便被送入微计算机。
If you enter text via a key board, then each time you depress a key, the binary digit code associated with that key is transmitted to the microcomputer.
但者其实也不要紧，因为字典里面的元素并不是用整数索引来排列的。所以你就可以直接用键来查找对应的键值。
But that's not a problem because the elements of a dictionary are never indexed with integer indices. Instead, you use the keys to look up the corresponding values.
你可以建立一个字典，用字母作为键，用该字母出现的次数作为对应的键值。
You could create a dictionary with characters as keys and counters as the corresponding values.
