本文整理了Java中org.springframework.web.servlet.ModelAndView.isEmpty()方法的一些代码示例，展示了ModelAndView.isEmpty()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。ModelAndView.isEmpty()方法的具体详情如下：
包路径：org.springframework.web.servlet.ModelAndView
类名称：ModelAndView
方法名：isEmpty

ModelAndView.isEmpty介绍

[英]Return whether this ModelAndView object is empty, i.e. whether it does not hold any view and does not contain a model.
[中]返回此ModelAndView对象是否为空，即它是否不包含任何视图且不包含模型。

代码示例

/**
 * Return whether this ModelAndView object is empty as a result of a call to {@link #clear}
 * i.e. whether it does not hold any view and does not contain a model.
 * <p>Returns {@code false} if any additional state was added to the instance
 * <strong>after</strong> the call to {@link #clear}.
 * @see #clear()
 */
public boolean wasCleared() {
  return (this.cleared && isEmpty());
