MimeBodyPart.updateHeaders介绍

[英]Examine the content of this body part and update the appropriate MIME headers. Typical headers that get set here are Content-Type and Content-Transfer-Encoding. Headers might need to be updated in two cases:

• A message being crafted by a mail application will certainly need to activate this method at some point to fill up its internal headers.
• A message read in from a Store will have obtained all its headers from the store, and so doesn't need this. However, if this message is editable and if any edits have been made to either the content or message structure, we might need to resync our headers.
  In both cases this method is typically called by the Message.saveChanges method.

If the #cachedContent field is not null (that is, it references a Multipart or Message object), then that object is used to set a new DataHandler, any stream data used to create this object is discarded, and the #cachedContent field is cleared.
[中]检查此正文部分的内容并更新相应的MIME标题。这里设置的典型标题是Content-Type和Content-Transfer-Encoding。在两种情况下，可能需要更新标题：
-邮件应用程序编写的邮件肯定需要在某个时候激活此方法以填充其内部标题。
-从存储中读入的消息将从存储中获取其所有头，因此不需要这样做。但是，如果此消息是可编辑的，并且如果对内容或消息结构进行了任何编辑，我们可能需要重新同步标题。
在这两种情况下，此方法通常由Message.saveChanges方法调用。
如果#cachedContent字段不为null（即，它引用多部分或消息对象），则该对象用于设置新的DataHandler，用于创建此对象的任何流数据都将被丢弃，#cachedContent字段将被清除。
