Interface MultipartDataSource
All Superinterfaces:
DataSource
public interface MultipartDataSource
implements DataSource
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.
