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

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.

Details

       Extends "DETAILS" 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.

Inheritance

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

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

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.

           Inherited, see "Constructors" in Mail::Message::Head

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

       $obj->isEmpty()

       $obj->knownNames()

       $obj->orderedFields()
           Inherited, see "The header" in Mail::Message::Head

   Accesstotheheader
       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

   Aboutthebody
       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.
