INHERITANCE
     Mail::Message::Head::Delayed realizes a Mail::Message::Head::Complete

     Mail::Message::Head::Delayed
       is a Mail::Message::Head

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

DESCRIPTION
    This object is used as place-holder, to be replaced by a Mail::Message::Head when someone
    accesses the header of a message.

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

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

    overload: ""
        Inherited, see "OVERLOADED" in Mail::Message::Head

    overload: bool
        Inherited, see "OVERLOADED" in Mail::Message::Head

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

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

    $obj->build($fields)
        You cannot create a delayed header with fields.

    Mail::Message::Head::Delayed->new(%options)
        Inherited, see "Constructors" 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.

    $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.

    $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

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

DIAGNOSTICS
    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.

    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.
