SYNOPSIS

15        !!! ALPHA CODE !!!
16
17        # change
18        use Mail::Internet;
19        use Mail::Header;
20        # into
21        use Mail::Message::Replace::MailInternet;
22        # in existing code, and the code should still work, but
23        # with the Mail::Message features.

DESCRIPTION

26       This module is a wrapper around a Mail::Message::Head::Complete, which
27       simulates a Mail::Header object.  The name-space of that module is
28       hijacked and many methods are added.
29
30       Most methods will work without any change, but you should test your
31       software again.  Small changes have been made to fold_length(),
32       header_hashref().

117       Extends "Access to the header" in Mail::Message::Head::Complete.
118
119       $obj->add( $line, [$index] )
120           Add a header line, which simply calls "Mail::Message::Head::add()"
121           on the header for the specified $line.  The $index is ignored, the
122           unfolded body of the field is returned.

141           Delete the fields with the specified $tag.  The deleted fields are
142           returned.  If no index is given, then all are removed.
143
144       $obj->get( $name, [$index] )
145           Get all the header fields with the specified $name.  In scalar
146           context, only the first fitting $name is returned.  Even when only
147           one $name is specified, multiple lines may be returned in list
148           context: some fields appear more than once in a header.

203           Replace the field named $tag. from place $index (by default the
204           first) by the $line.  When $tag is "undef", it will be extracted
205           from the $line first.  This calls

335   Access to the header
336   Simulating Mail::Header
337       $obj->as_string()
338           Returns the whole header as one big scalar.  Calls
339           Mail::Message::Head::Complete::string().
340
341       $obj->cleanup()
342           Cleanup memory usage.  Not needed here.
343
344       $obj->combine( $tag, [$with] )
345           I do not see any valid reason for this command, so did not
346           implement it.
347
348       $obj->dup()
349           Duplicate the header, which is simply clone().
350
351       $obj->empty()
352           Clean-out the whole hash. Better not use this (simply create
353           another header object), although it should work.
354
355       $obj->exists()
356           Returns whether there are any fields.
357
358       $obj->extract(ARRAY)
359           Extract (and remove) header fields from the array.
360
361       $obj->fold( [$length] )
362           Refold all fields in the header, to $length or whatever
363           fold_length() returns.
364
365       $obj->fold_length( [[$tag], $length] )
366           Returns the line wrap, optionally after setting it to $length.  The
367           old value is returned.  The $tag argument is ignored, because it is
368           silly to have different lines fold in different ways.  This method
369           cannot be called statically anymore.
370
371       $obj->header( [ARRAY] )
372           Extract the fields from the ARRAY, if specified, and then fold the
373           fields.  Returned is an array with all fields, produced via
374           orderedFields().
375
376       $obj->header_hashref(HASH)
377           If you are using this method, you must be stupid... anyway: I do
378           not want to support it for now: use add() and friends.
379
380       $obj->mail_from( ['IGNORE'|'ERROR'|'COERCE'|'KEEP'] )
381           What to do when a header line in the form `From ' is encountered.
382           Valid values are "IGNORE" - ignore and discard the header, "ERROR"
383           - invoke an error (call die), "COERCE" - rename them as Mail-From
384           and "KEEP" - keep them.
385
386       $obj->modify( [BOOLEAN] )
387           Refold the headers when they are added.
388
389       $obj->read($file)
390           Read the header from the $file.
391
392       $obj->tags()
393           Returns all the names of fields, implemented by
394           Mail::Message::Head::Complete::names().
395
396       $obj->unfold( [$tag] )
397           Remove the folding for all instances of $tag, or all fields at
398           once.
399
400   The nasty bits
401       $obj->isa($class)
402       Mail::Message::Replace::MailHeader->isa($class)
403           Of course, the "isa()" class inheritance check should not see our
404           nasty trick.

DIAGNOSTICS

410       Warning: Cannot remove field $name from header: not found.
411           You ask to remove a field which is not known in the header.  Using
412           delete(), reset(), or set() to do the job will not result in
413           warnings: those methods check the existence of the field first.
414
415       Warning: Field objects have an implied name ($name)
416       Error: Package $package does not implement $method.
417           Fatal error: the specific package (or one of its superclasses) does
418           not implement this method where it should. This message means that
419           some other related classes do implement this method however the
420           class at hand does not.  Probably you should investigate this and
421           probably inform the author of the package.
