Class IMAPMessage

Direct Known Subclasses:

IMAPNestedMessage

public class IMAPMessage
extends MimeMessage

This class implements an IMAPMessage object.

An IMAPMessage object starts out as a light-weight object. It gets filled-in incrementally when a request is made for some item. Or when a prefetch is done using the FetchProfile.

An IMAPMessage has a messageNumber and a sequenceNumber. The messageNumber is its index into its containing folder's messageCache. The sequenceNumber is its IMAP sequence-number.
