net.rim.blackberry.api.mail
Interface Part

All Known Implementing Classes:
BodyPart, FileSupportedAttachmentPart, Message, MimeBodyPart, PDAPContactAttachmentPart, SupportedAttachmentPart, TextBodyPart, UnsupportedAttachmentPart
public interface Part

Defines the header fields and contents of a Message or a BodyPart, in a Multipart object.

A part consists of a set of header fields and a body (contents).

Each part has a standard set of header fields (also called attributes) that are common to most existing mail systems. The BlackBerry Mail API currently only supports the CONTENT_TYPE header type, which defines the MIME content type of the body's contents. Use Part.getContentType() to retrieve the content type, and Part.getContent() to retrieve the actual content.

Use Part.writeTo(java.io.OutputStream) to write out the part's content to a byte stream in a form suitable for mail transmission. This byte stream is typically an aggregation of the header fields and contents. For more information, see RFC 2045 - Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies.
