/* 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".
