MultipartDataSource (Java EE 5)

注意，MultipartDataSource 的数据也可以用作输入流。

此接口通常由预先解析 multipart 正文的提供者实现，例如 IMAP 提供者。

MultipartDataSource is a DataSource that contains body parts. This allows "mail aware" DataContentHandlers to be implemented more efficiently by being aware of such DataSources and using the appropriate methods to access BodyParts.

Note that the data of a MultipartDataSource is also available as an input stream.

This interface will typically be implemented by providers that preparse multipart bodies, for example an IMAP provider.
