本文整理了Java中com.vaadin.v7.ui.Table.refreshRowCache()方法的一些代码示例，展示了Table.refreshRowCache()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。Table.refreshRowCache()方法的具体详情如下：
包路径：com.vaadin.v7.ui.Table
类名称：Table
方法名：refreshRowCache

Table.refreshRowCache介绍

[英]Discards and recreates the internal row cache. Call this if you make changes that affect the rows but the information about the changes are not automatically propagated to the Table.

Do not call this e.g. if you have updated the data model through a Property. These types of changes are automatically propagated to the Table.

A typical case when this is needed is if you update a generator (e.g. CellStyleGenerator) and want to ensure that the rows are redrawn with new styles.

Note that calling this method is not cheap so avoid calling it unnecessarily.
[中]丢弃并重新创建内部行缓存。如果所做的更改会影响行，但有关更改的信息不会自动传播到表中，请调用此函数。
例如，如果您通过属性更新了数据模型，则不要调用此选项。这些类型的更改会自动传播到表中。
需要这样做的典型情况是，如果更新生成器（例如CellStyleGenerator），并希望确保使用新样式重新绘制行。
请注意，调用此方法并不便宜，因此请避免不必要地调用它。
