Mail::Message::TransfeUser(Contributed Perl DocMail::Message::TransferEnc(3pm)



NAME
       Mail::Message::TransferEnc - message transfer encoder/decoder

INHERITANCE
        Mail::Message::TransferEnc
          is a Mail::Reporter

        Mail::Message::TransferEnc is extended by
          Mail::Message::TransferEnc::Base64
          Mail::Message::TransferEnc::Binary
          Mail::Message::TransferEnc::EightBit
          Mail::Message::TransferEnc::QuotedPrint
          Mail::Message::TransferEnc::SevenBit

SYNOPSIS
        my Mail::Message $msg = ...;
        my $decoded = $msg->decoded;
        my $encoded = $msg->encode(transfer => 'base64');

DESCRIPTION
       This class is the base for various encoders and decoders, which are
       used during transport of the message.  This packages, and all which are
       derived, are invoked by the message's Mail::Message::decoded() and
       Mail::Message::encode() methods:

        my $message = $folder->message(3);
        my $decoded_body = $message->decoded;
        my $encoded_body = $message->encode(transfer => 'base64');

       The following coders/decoders are currently available:

       o   Mail::Message::TransferEnc::Base64

           "base64" for binary information.

       o   Mail::Message::TransferEnc::SevenBit

           "7bit" for plain old ASCII characters only.

       o   Mail::Message::TransferEnc::EightBit

           "8bit" for extended character set data, not encoded.

       o   Mail::Message::TransferEnc::QuotedPrint

           "quoted-printable" encdoded extended character set data.

METHODS
       Constructors

       Mail::Message::TransferEnc->new(OPTIONS)

           See "Constructors" in Mail::Reporter

       The Encoder

       Mail::Message::TransferEnc->addTransferEncoder(TYPE, CLASS)

           Adds one new encoder to the list known by the Mail::Box suite.  The
           TYPE is found in the message's header in the
           "Content-Transfer-Encoding" field.

       $obj->create(TYPE, OPTIONS)

           Create a new coder/decoder based on the required type.

       $obj->name

           The name of the encoder.  Case is not significant.

       Encoding

       $obj->check(BODY, OPTIONS)

           Check whether the body is correctly encoded.  If so, the body
           reference is returned with the "checked" flag set.  Otherwise, a
           new object is created and returned.

            Option     --Default
            result_type  <type of source body>

           . result_type => CLASS

               The type of the body to be produced, when the checker decides
               to return modified data.

       $obj->decode(BODY [, OPTIONS])

           Use the encoder to decode the content of BODY.  A new body is
           returned.

            Option     --Default
            result_type  <type of source body>

           . result_type => CLASS

               The type of the body to be produced, when the decoder decides
               to return modified data.

       $obj->encode(BODY, OPTIONS)

           Use the encoder to encode the content of BODY.

            Option     --Default
            result_type  <type of source body>

           . result_type => CLASS

               The type of the body to be produced, when the decoder decides
               to return modified data.

DIAGNOSTICS
       Error: Decoder for transfer encoding $type does not work: $@

           Compiling the required transfer encoding resulted in errors, which
           means that the decoder can not be used.

       Warning: No decoder for transfer encoding $type.

           A decoder for the specified type of transfer encoding is not
           implemented.

       Error: Package $package does not implement $method.

           Fatal error: the specific package (or one of its superclasses) does
           not implement this method where it should. This message means that
           some other related classes do implement this method however the
           class at hand does not.  Probably you should investigate this and
           probably inform the author of the package.
