💖 Mail::Message::Head::Delayed — the manual page ✨

okay bestie, so this is Mail::Message::Head::Delayed(3pm) from the User Contributed Perl Documentation (that's the 3pm section, iykyk). It ships inside the Mail-Box distribution and it is, fr fr, one of those little modules that does one tiny job perfectly and then dips. Let's get into it 🫶

🌸 NAME

Mail::Message::Head::Delayed — a not-read header of a Mail::Message

🧬 INHERITANCE

  • Mail::Message::Head::Delayed realizes a Mail::Message::Head::Complete
  • Mail::Message::Head::Delayed
    • is a Mail::Message::Head
    • is a Mail::Reporter

✨ SYNOPSIS

my $delayed = Mail::Message::Head::Delayed->new(...)
$delayed->isa('Mail::Message::Head')  # true
$delayed->guessBodySize               # undef
$delayed->isDelayed                   # true

🦋 DESCRIPTION

So basically this object is a place-holder 🎀. It sits there being a vibe until somebody actually accesses the header of a message, and then it gets replaced by a Mail::Message::Head. That's the whole arc. Character development: delayed header → real header.

Extends "DESCRIPTION" in Mail::Message::Head.

🔥 OVERLOADED

Extends "OVERLOADED" in Mail::Message::Head.

  • overload: "" stringifaction — inherited, see "OVERLOADED" in Mail::Message::Head
  • overload: bool true/false — inherited, see "OVERLOADED" in Mail::Message::Head

👑 METHODS

Extends "METHODS" in Mail::Message::Head.

🎀 Constructors

Extends "Constructors" in Mail::Message::Head.

  • $class->build($fields) — You cannot create a delayed header with fields. Improves base, see "Constructors" in Mail::Message::Head
  • $class->new(%options) — inherited, see "Constructors" in Mail::Message::Head

🌸 Attributes

Extends "Attributes" in Mail::Message::Head.

💌 The header

Extends "The header" in Mail::Message::Head.

  • $obj->isDelayed() — inherited, see "The header" in Mail::Message::Head
  • $obj->isEmpty() — inherited, see "The header" in Mail::Message::Head
  • $obj->isModified() — inherited, see "The header" in Mail::Message::Head
  • $obj->knownNames() — inherited, see "The header" in Mail::Message::Head
  • $obj->message( [$message] ) — inherited, see "The header" in Mail::Message::Head
  • $obj->modified( [BOOLEAN] ) — inherited, see "The header" in Mail::Message::Head
  • $obj->orderedFields() — inherited, see "The header" in Mail::Message::Head

🔍 Access to the header

Extends "Access to the header" in Mail::Message::Head.

  • $obj->get( $name, [$index] ) — Get the information about the header line $name. Realization will take place. ✨ Improves base, see "Access to the header" in Mail::Message::Head
  • $obj->study( $name, [$index] ) — inherited, see "Access to the header" in Mail::Message::Head

🍓 About the body

Extends "About the body" in Mail::Message::Head.

  • $obj->guessBodySize() — On a delayed head, this returns undef, because when there is no header there is also no body. 💀 For messages in directory or network organized folders, Mail::Message::size() usually will give a figure for the whole message without much cost. Subtract a few hundred bytes for the header, and you will get a good estimate. Improves base, see "About the body" in Mail::Message::Head
  • $obj->guessTimeStamp() — Make a guess about when the message was originally posted. On a delayed head, this returns undef. For messages in directory or network organized folders, Mail::Message::timestamp() usually will give a figure without much cost.
  • $obj->isMultipart() — inherited, see "About the body" in Mail::Message::Head

🧚 Internals

Extends "Internals" in Mail::Message::Head.

  • $obj->addNoRealize($field) — inherited, see "Internals" in Mail::Message::Head
  • $obj->addOrderedFields($fields) — inherited, see "Internals" in Mail::Message::Head
  • $obj->fileLocation() — inherited, see "Internals" in Mail::Message::Head
  • $obj->load() — inherited, see "Internals" in Mail::Message::Head
  • $obj->moveLocation($distance) — inherited, see "Internals" in Mail::Message::Head
  • $obj->read($parser) — inherited, see "Internals" in Mail::Message::Head
  • $obj->setNoRealize($field) — Not possible. 🚫 Improves base, see "Internals" in Mail::Message::Head

🙈 Error handling

Extends "Error handling" in Mail::Message::Head.

  • $obj->AUTOLOAD() — inherited, see "Error handling" in Mail::Reporter
  • $obj->notImplemented() — inherited, see "Error handling" in Mail::Reporter

🧹 Cleanup

Extends "Cleanup" in Mail::Message::Head.

  • $obj->DESTROY() — inherited, see "Cleanup" in Mail::Reporter

🌈 DETAILS

Extends "DETAILS" in Mail::Message::Head.

💅 DIAGNOSTICS

  • Error: attempt to set field on a delayed header. — Cast by setNoRealize()
  • Error: cannot build() a delayed header. — A delayed message header cannot contain any information, so cannot be build. You can construct complete or subset headers. Cast by build()
  • Error: class $package does not implement method $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. Cast by notImplemented()
