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

Position介绍

[英]Positions describe text ranges of a document. Positions are adapted to changes applied to that document. The text range is specified by an offset and a length. Positions can be marked as deleted. Deleted positions are considered to no longer represent a valid text range in the managing document.

Positions attached to documents are usually updated by position updaters. Because position updaters are freely definable and because of the frequency in which they are used, the fields of a position are made publicly accessible. Clients other than position updaters are not allowed to access these public fields.

Positions cannot be used as keys in hash tables as they override equals and hashCode as they would be value objects.
[中]位置描述文档的文本范围。根据应用于该文档的更改调整位置。文本范围由偏移量和长度指定。位置可以标记为已删除。删除的位置将被视为不再代表管理文档中的有效文本范围。
附加到文档的位置通常由位置更新程序更新。由于职位更新程序是可自由定义的，而且使用频率很高，因此职位的字段可以公开访问。不允许位置更新程序以外的客户端访问这些公共字段。
位置不能用作哈希表中的键，因为它们会重写equals和hashCode，因为它们是值对象。
