Item-Class的意思|示意

OmniFind is a repository that does not have any notion of an item class; instead, it relies on the user to define what properties can be set for a particular item.

OmniFind是一种没有任何项目类概念的存储库，相反，它依靠用户来定义该为某一个项目设置什么样的属性。

The default item class on a RepoItem is null, so the item class on all Folder objects in the example connector will also be null.

RepoItem 上的默认条目类是 null，所以示例连接器中所有 Folder 对象上的条目类也是 null。

On each result row is a certain number of properties that are always accessible, and these properties became the global item class.

对于结果的每一行，有一定数量的总是能够访问的属性，这些属性就变成了全局项目类。

Given an object being tested (such as item in Listing 5) and a target class (Integer) being cast to, the class loader checks the following rules.

当检查对象(例如清单5中的item)并把类型转换成目标类(Integer)时，类装入器会检查以下规则。

It's important to note that not all of the properties in the item class will necessarily exist on every Content object in that class, and that is acceptable.

一定要注意，条目类中的所有属性不一定在这个类中的每个 Content 对象上都存在，这是可以接受的。

In this case, a global item class can be defined for the connector, to serve as a way to retrieve those properties that can always be accessed.

在这种情况下，可以为连接器定义一个全局项目类，作为对那些一直可以进行访问的属性进行检索的方法。
