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. These 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:
- •
- Mail::Message::TransferEnc::Base64
"base64" for binary information.
- •
- Mail::Message::TransferEnc::SevenBit
"7bit" for plain old ASCII characters only.
- •
- Mail::Message::TransferEnc::EightBit
"8bit" for extended character set data, not encoded.
- •
- 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.
