<span>AbstractDocument.Content接口的实现使用与emacs使用的类似的间隙缓冲区来实现。</span>
<span>底层存储是一系列unicode字符，在某处有差距。</span>
<span>差距被移动到更改的位置，以利用大多数更改位于相同位置的常见行为。</span>
<span>在间隙边界发生的变化通常是便宜的，并且移动间隙通常比直接移动阵列内容以适应变化更便宜。</span>
<p> <span>跟踪变化的位置通常也很便宜。</span> <span>位置实现（标记）存储数组索引，并且可以容易地从当前间隙位置计算顺序位置。</span> <span>当间隙移动时，更改仅需要更新旧间隙和新间隙边界之间的标记，因此通常更新标记相当便宜。</span> <span>标记被存储排序，以便它们可以通过二进制搜索快速定位。</span> <span>这增加了添加商标的成本，并降低了保持标记更新的成本。</span> </p>
