MIME::Field::ContType(User Contributed Perl DocumentatMIME::Field::ContType(3)

NAME
       MIME::Field::ContType - a "Content-type" field

DESCRIPTION
       A subclass of Mail::Field.

       Don't use this class directly... its name may change in the future!
       Instead, ask Mail::Field for new instances based on the field name!

SYNOPSIS
	   use Mail::Field;
	   use MIME::Head;

	   # Create an instance from some text:
	   $field = Mail::Field->new('Content-type',
				     'text/HTML; charset="US-ASCII"');

	   # Get the MIME type, like 'text/plain' or 'x-foobar'.
	   # Returns 'text/plain' as default, as per RFC-1521:
	   my ($type, $subtype) = split('/', $field->type);

	   # Get generic information:
	   print $field->name;

	   # Get information related to "message" type:
	   if ($type eq 'message') {
	       print $field->id;
	       print $field->number;
	       print $field->total;
	   }

	   # Get information related to "multipart" type:
	   if ($type eq 'multipart') {
	       print $field->boundary;		  # the basic value, fixed up
	       print $field->multipart_boundary;  # empty if not a multipart message!
	   }

	   # Get information related to "text" type:
	   if ($type eq 'text') {
	       print $field->charset;	   # returns 'us-ascii' as default
	   }

PUBLIC INTERFACE
       boundary
	   Return the boundary field.  The boundary is returned exactly as
	   given in the "Content-type:" field; that is, the leading double-
	   hyphen ("--") is not prepended.

	   (Well, almost exactly... from RFC-1521:

	      (If a boundary appears to end with white space, the white space
	      must be presumed to have been added by a gateway, and must be deleted.)

	   so we oblige and remove any trailing spaces.)

	   Returns the empty string if there is no boundary, or if the bound-
	   ary is illegal (e.g., if it is empty after all trailing whitespace
	   has been removed).

       multipart_boundary
	   Like "boundary()", except that this will also return the empty
	   string if the message is not a multipart message.  In other words,
	   there's an automatic sanity check.

       type
	   Try real hard to determine the content type (e.g., "text/plain",
	   "image/gif", "x-weird-type", which is returned in all-lowercase.

	   A happy thing: the following code will work just as you would want,
	   even if there's no subtype (as in "x-weird-type")... in such a
	   case, the $subtype would simply be the empty string:

	       ($type, $subtype) = split('/', $head->mime_type);

	   If the content-type information is missing, it defaults to
	   "text/plain", as per RFC-1521:

	       Default RFC-822 messages are typed by this protocol as plain text in
	       the US-ASCII character set, which can be explicitly specified as
	       "Content-type: text/plain; charset=us-ascii".  If no Content-Type is
	       specified, this default is assumed.

	   Note: under the "be liberal in what we accept" principle, this rou-
	   tine no longer syntax-checks the content type.  If it ain't empty,
	   just downcase and return it.

NOTES
       Since nearly all (if not all) parameters must have non-empty values to
       be considered valid, we just return the empty string to signify missing
       fields.	If you need to get the real underlying value, use the inher-
       ited "param()" method (which returns undef if the parameter is miss-
       ing).
