本文整理了Java中com.vaadin.v7.data.Item类的一些代码示例，展示了Item类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Item类的具体详情如下：
包路径：com.vaadin.v7.data.Item
类名称：Item

Item介绍

[英]Provides a mechanism for handling a set of Properties, each associated to a locally unique non-null identifier. The interface is split into subinterfaces to enable a class to implement only the functionalities it needs.
[中]提供处理一组属性的机制，每个属性都与本地唯一的非空标识符关联。接口被拆分为子接口，以使类能够仅实现其所需的功能。
