本文整理了Java中org.openide.cookies.EditorCookie类的一些代码示例，展示了EditorCookie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。EditorCookie类的具体详情如下：
包路径：org.openide.cookies.EditorCookie
类名称：EditorCookie

EditorCookie介绍

[英]Cookie defining standard operations with a text document and an editor that can display it. The cookie extends LineCookie because all implementations of editors should support access by lines.

The cookie provides interfaces for opening the file, closing the editor, background loading, saving of the document, and notification of modification.

Warning: it is not guaranteed that the document returned from this cookie will persist for the full lifetime of the cookie. That is, if the editor window is closed and then reopened, it is possible for the document to change. The EditorCookie.Observable allows listening to changes of the state of the document. You should do this if you are listening to changes in the document itself, as otherwise you would get no notifications from a reopened document.
[中]Cookie使用文本文档和可显示文本文档的编辑器定义标准操作。cookie扩展了LineCookie，因为所有编辑器的实现都应该支持按行访问。
cookie提供用于打开文件、关闭编辑器、后台加载、保存文档以及通知修改的接口。
警告：不能保证从此cookie返回的文档在cookie的整个生命周期内保持不变。也就是说，如果编辑器窗口关闭然后重新打开，文档可能会发生更改。EditorCookie.Observable允许监听文档状态的更改。如果您正在侦听文档本身的更改，则应该执行此操作，否则您将不会从重新打开的文档中收到任何通知。
