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:

METHODS

Constructors

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

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.
