This structure also has other fields like inquiry type, object UUID, interface ID among others.
所使用的表示法取决于字段是简单对象类型、简单原语类型还是数组类型。

The fields or objects that the team was uncertain about were often central to the function of a given device.
下一步，您需要指定如何将每个事件对象字段映射到中间对象字段。
Next you need to specify how each of the event object fields is mapped to the intermediate object fields.
它包括对象的名称和字段的数组。
下一步，您需要定义如何在中间对象的基础上构造操作，以及定义从中间对象字段到操作字段的映射。
Next, you need to define how the actions are constructed from intermediate objects and the mapping from the intermediate object fields to the action fields.
JSDT试图解析对象的所有字段和方法。
JSDT attempts to resolve all fields and methods for an object.
定义中间对象字段与事件字段之间的映射。
Define the mapping between intermediate object fields and event fields.
尤其是，要检查应该填充的中间对象字段是否存在。
In particular, look to see whether intermediate object fields that should be populated are there or not.
这将指定在事件字段的基础上构造中间对象的所有字段。
This specifies all the fields of the intermediate object that are constructed from event fields.
在编写这些查询时，有一点需要加以注意，即要将定制对象和字段与标准对象和字段区分开。
An important thing to remember when you write these queries is to distinguish custom objects and fields from standard objects and fields.
如果不需要访问某对象的字段，将方法设置为静态，调用会加速15%到20%。
If you don't need to access an object's fields, make your method static. Invocations will be about 15%-20% faster.
它们通常用于计算事件中不存在的中间对象字段。
They are typically used to compute fields of the intermediate object that are not present in the event.
在调用某个方法时，您经常会在传递一个有多个字段的对象以及单独传递字段之间做出选择。
When calling a method, you can often choose between passing a single object that has multiple fields and passing the fields individually.
在面向对象设计中，传递对象通常能提供较好的封装，因为对象字段的变化不需要改变方法签名。
With object-oriented designs, passing the object often provides better encapsulation, in that changes in the object fields don't require changes to the method signature.
这将指定在事件字段的基础上构建中间对象的字段。
This specifies the fields of the intermediate object that are built from the event fields.
要测量数据的“更新程度”，您可能决定向该对象添加时间戳记字段，以便容易地检测对象是否与后备存储器同步。
To gauge the "freshness" of the data, you might decide to add a timestamp field to the object so that you could easily detect whether the object and the backing store were out of sync.
所生成的页面上的输入字段的顺序取决于在业务对象定义中定义对应字段的顺序。
The order of the input fields on the generated page depends on the order in which the corresponding fields are defined in the business object definition.
