类名称：ZNRecord
方法名：update

ZNRecord.update介绍

[英]Replace functionality is used to update this ZNRecord with the given ZNRecord. The value of a field in this record will be replaced with the value of the same field in given record if it presents. If there is new field in given ZNRecord but not in this record, add that field into this record. The list fields and map fields will be replaced as a single entry.
[中]替换功能用于使用给定的ZNRecord更新此ZNRecord。此记录中某个字段的值将替换为给定记录中同一字段的值（如果出现）。如果给定记录中有新字段，但此记录中没有，请将该字段添加到此记录中。列表字段和地图字段将被替换为单个条目。
