类名称：Patch

Patch介绍

[英]Describes the patch holding all deltas between the original and revised texts.
[中]描述包含原始文本和修订文本之间所有增量的补丁。

代码示例

代码示例来源：origin: apache/phoenix

/**
 * Do a diff between exported query results and temporary CSV file
 *
 * @param query
 * @param newCSV
 * @return
 */
public boolean doDiff(Query query, String newCSV) {
  List<String> original = fileToLines(getCSVName(query, PherfConstants.EXPORT_DIR, ""));
  List<String> newLines = fileToLines(newCSV);
  Patch patch = DiffUtils.diff(original, newLines);
  if (patch.getDeltas().isEmpty()) {
    logger.info("Match: " + query.getId() + " with " + newCSV);
    return true;
  } else {
    logger.error("DIFF FAILED: " + query.getId() + " with " + newCSV);
    return false;
  }
}
