.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This class represents a multipart email part which contains other parts.
.SH "API"
.IX Header "API"
This class provides the following methods:
.SS "Courriel::Part::Multipart\->new( ... )"
.IX Subsection "Courriel::Part::Multipart->new( ... )"
This method creates a new part object. It accepts the following parameters:
.IP "\(bu" 4
parts
.Sp
An array reference of part objects (either Single or Multipart). This is
required, but could be empty.
.IP "\(bu" 4
content_type
.Sp
A Courriel::Header::ContentType object. This defaults to one with a mime
type of \*(L"multipart/mixed\*(R".
.IP "\(bu" 4
boundary
.Sp
The part boundary. If none is provided, a unique value will be generated.
.IP "\(bu" 4
preamble
.Sp
Content that appears before the first part boundary. This will be seen by email
clients that don't understand multipart messages.
.IP "\(bu" 4
epilogue
.Sp
Content that appears after the final part boundary. The spec allows for this,
but it's probably not very useful.
.IP "\(bu" 4
headers
.Sp
A Courriel::Headers object containing headers for this part.
.ie n .SS "$part\->\fBparts()\fP"
.el .SS "\f(CW$part\fP\->\fBparts()\fP"
.IX Subsection "$part->parts()"
Returns an array (not a reference) of the parts this part contains.
.ie n .SS "$part\->\fBpart_count()\fP"
.el .SS "\f(CW$part\fP\->\fBpart_count()\fP"
.IX Subsection "$part->part_count()"
Returns the number of parts this part contains.
.ie n .SS "$part\->\fBboundary()\fP"
.el .SS "\f(CW$part\fP\->\fBboundary()\fP"
.IX Subsection "$part->boundary()"
Returns the part boundary.
.ie n .SS "$part\->\fBmime_type()\fP"
.el .SS "\f(CW$part\fP\->\fBmime_type()\fP"
.IX Subsection "$part->mime_type()"
Returns the mime type for this part.
.ie n .SS "$part\->\fBcontent_type()\fP"
.el .SS "\f(CW$part\fP\->\fBcontent_type()\fP"
.IX Subsection "$part->content_type()"
Returns the Courriel::Header::ContentType object for this part.
.ie n .SS "$part\->\fBheaders()\fP"
.el .SS "\f(CW$part\fP\->\fBheaders()\fP"
.IX Subsection "$part->headers()"
Returns the Courriel::Headers object for this part.
.ie n .SS "$part\->\fBis_inline()\fP, $part\->\fBis_attachment()\fP"
.el .SS "\f(CW$part\fP\->\fBis_inline()\fP, \f(CW$part\fP\->\fBis_attachment()\fP"
.IX Subsection "$part->is_inline(), $part->is_attachment()"
These methods always return false, but exist for the sake of providing a
consistent \s-1API\s0 between Single and Multipart part objects.
.ie n .SS "$part\->\fBis_multipart()\fP"
.el .SS "\f(CW$part\fP\->\fBis_multipart()\fP"
.IX Subsection "$part->is_multipart()"
Returns true.
.ie n .SS "$part\->\fBpreamble()\fP"
.el .SS "\f(CW$part\fP\->\fBpreamble()\fP"
.IX Subsection "$part->preamble()"
The preamble as passed to the constructor.
.ie n .SS "$part\->\fBepilogue()\fP"
.el .SS "\f(CW$part\fP\->\fBepilogue()\fP"
.IX Subsection "$part->epilogue()"
The epilogue as passed to the constructor.
.ie n .SS "$part\->\fBcontainer()\fP"
.el .SS "\f(CW$part\fP\->\fBcontainer()\fP"
.IX Subsection "$part->container()"
Returns the Courriel or Courriel::Part::Multipart object to which this
part belongs, if any. This is set when the part is added to another object.
.ie n .SS "$part\->stream_to( output => $output )"
.el .SS "\f(CW$part\fP\->stream_to( output => \f(CW$output\fP )"
.IX Subsection "$part->stream_to( output => $output )"
This method will send the stringified part to the specified output. The output
can be a subroutine reference, a filehandle, or an object with a \f(CW\*(C`print()\*(C'\fR
method. The output may be sent as a single string, as a list of strings, or via
multiple calls to the output.
.ie n .SS "$part\->\fBas_string()\fP"
.el .SS "\f(CW$part\fP\->\fBas_string()\fP"
.IX Subsection "$part->as_string()"
Returns the part as a string, along with its headers. Lines will be terminated
with \*(L"\er\en\*(R".
.SH "ROLES"
.IX Header "ROLES"
This class does the \f(CW\*(C`Courriel::Role::Part\*(C'\fR and \f(CW\*(C`Courriel::Role::Streams\*(C'\fR
roles.
