BinaryMessage
class to send and receive other application data, such as for pushing compressed financial

Managing the Multiple Parts of a MultipartMessage
Working with
MultipartMessage
instances is a little different than working with other
Message
subclasses, because the payload for an MMS message consists of one or more
parts
. Each part is a single multimedia entity such as an image, a block of text, or a
sound, much like a conventional e-mail message. Figure 14-2 shows a schematic
representation of a message with multiple parts.
Figure 14-2.
A schematic representation of a MultipartMessage instance
Instances of
MultipartMessage
have several fields:
•
A timestamp
: Inherited from the
Message
class, a timestamp is available via the
getTimestamp
method.
•
A starting content ID
: The ID is a
String
that names the first part of the message
to be displayed to the user. It's available via the
getStartContentId
and
setStartContentId
methods.
