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.

       See documentation in the base class.

OVERLOADED

       See documentation in the base class.

       overload: ""()
           See "OVERLOADED" in Mail::Message::Head

       overload: bool()
           See "OVERLOADED" in Mail::Message::Head

METHODS

       See documentation in the base class.

   Constructors
       See documentation in the base class.

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

       Mail::Message::Head::Delayed->new(OPTIONS)
           See "Constructors" in Mail::Message::Head

   The header
       See documentation in the base class.

       $obj->isDelayed()
           See "The header" in Mail::Message::Head

       $obj->isEmpty()
           See "The header" in Mail::Message::Head

       $obj->isModified()
           See "The header" in Mail::Message::Head

       $obj->knownNames()
           See "The header" in Mail::Message::Head

       $obj->message([MESSAGE])
           See "The header" in Mail::Message::Head

       $obj->modified([BOOLEAN])
           See "The header" in Mail::Message::Head

       $obj->orderedFields()
           See "The header" in Mail::Message::Head

   Access to the header
       See documentation in the base class.

       $obj->get(NAME [,INDEX])
           Get the information about the header line NAME.  Realization will take place.

       $obj->study(NAME [,INDEX])
           See "Access to the header" in Mail::Message::Head

   About the body
       See documentation in the base class.

       $obj->guessBodySize()
           On a delayed head, this retuns "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()
           See "About the body" 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.
