/* The MimeMultipart class class implements the objects representing all of
the "multipart/" MIME types. In addition to the methods inherited from
MimeContainer, it provides the following methods and class variables:
int create_child (MimeObject *obj)
When it has been determined that a new sub-part should be created,
this method is called to do that. The default value for this method
does it in the usual multipart/mixed way. The headers of the object-
to-be-created may be found in the `hdrs' slot of the `MimeMultipart'
object.
XP_Bool output_child_p (MimeObject *parent, MimeObject *child)
Whether this child should be output. Default method always says `yes'.
int parse_child_line (MimeObject *obj, char *line, int32 length,
XP_Bool first_line_p)
When we have a line which should be handed off to the currently-active
child object, this method is called to do that. The `first_line_p'
variable will be true only for the very first line handed off to this
sub-part. The default method simply passes the line to the most-
recently-added child object.
int close_child (MimeObject *self)
When we reach the end of a sub-part (a separator line) this method is
called to shut down the currently-active child. The default method
simply calls `parse_eof' on the most-recently-added child object.
MimeMultipartBoundaryType check_boundary (MimeObject *obj,
const char *line, int32 length)
This method is used to examine a line and determine whether it is a
part boundary, and if so, what kind. It should return a member of
the MimeMultipartBoundaryType describing the line.
const char *default_part_type
This is the type which should be assumed for sub-parts which have
no explicit type specified. The default is "text/plain", but the
"multipart/digest" subclass overrides this to "message/rfc822".
