本文整理了Java中com.vaadin.v7.data.Property类的一些代码示例，展示了Property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。Property类的具体详情如下：
包路径：com.vaadin.v7.data.Property
类名称：Property

Property介绍

[英]The Property is a simple data object that contains one typed value. This interface contains methods to inspect and modify the stored value and its type, and the object's read-only state.

The Property also defines the events ReadOnlyStatusChangeEvent and ValueChangeEvent, and the associated listener and notifier interfaces.

The Property.Viewer interface should be used to attach the Property to an external data source. This way the value in the data source can be inspected using the Property interface.

The Property.editor interface should be implemented if the value needs to be changed through the implementing class.
[中]Property是一个简单的数据对象，包含一个类型化的值。此接口包含检查和修改存储值及其类型以及对象只读状态的方法。
Property还定义了事件ReadOnlyStatusChangeEvent和ValueChangeEvent，以及相关的listener和notifier接口。
Property.Viewer接口应用于将属性附加到外部数据源。这样，可以使用Property接口检查数据源中的值。
如果需要通过实现类更改值，则应实现Property.editor接口。
