Interface MultipartDataSource

  • All Superinterfaces:
    jakarta.activation.DataSource
    public interface MultipartDataSource
extends jakarta.activation.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.
