org.apache.commons.text.diff有什么用？
What is org.apache.commons.text.diff used for?
我阅读了 org.apache.commons.text.diff 的文档。但是我还是不明白类InsertCommand、EditCommand、KeepCommand和DeleteCommand有什么用。有人知道它们是什么以及如何使用它们吗？
如果比较两个字符串：
A B C E F H （旧）
A C D E G H （新）
那么你的"script"是：
Keep 'A'
Delete 'B'
Keep 'C'
Insert 'D'
Keep 'E'
Delete 'F'
Insert 'G'
Keep 'H'
如 EditCommand 的 javadoc 中所述：
When two objects sequences are compared through the StringsComparator.getScript method, the result is provided has a script containing the commands that progressively transform the first sequence into the second one.
