NAME
Mail::Message::Head::Subset - subset of header information of a message
INHERITANCE
Mail::Message::Head::Subset realizes a Mail::Message::Head::Complete
Mail::Message::Head::Subset
is a Mail::Message::Head
is a Mail::Reporter
SYNOPSIS
my $subset = Mail::Message::Head::Subset->new(...)
$subset->isa('Mail::Message::Head') # true
$subset->guessBodySize # integer or undef
$subset->isDelayed # true
DESCRIPTION
Some types of folders contain an index file which lists a few lines of information per
messages. Especially when it is costly to read header lines, the index speeds-up access
considerably. For instance, the subjects of all messages are often wanted, but waiting
for a thousand messages of the folder to be read may imply a thousand network reads (IMAP)
or file openings (MH)
When you access header fields which are not in the header subset, the whole header has to
be parsed (which may consume considerable time, depending on the type of folder).

Access to the header
Extends "Access to the header" in Mail::Message::Head.
$obj->count($name)
Count the number of fields with this $name. If the $name cannot be found, the full
header get loaded. In case we find any $name field, it is decided we know all of
them, and loading is not needed.
$obj->get( $name, [$index] )
Get the data which is related to the field with the $name. The case of the characters
in $name does not matter. When a $name is used which is not known yet, realization
will take place.
$obj->study( $name, [$index] )

About the body
Extends "About the body" in Mail::Message::Head.
$obj->guessBodySize()
The body size is defined in the "Content-Length" field. However, this field may not
be known. In that case, a guess is made based on the known "Lines" field. When also
that field is not known yet, "undef" is returned.

DIAGNOSTICS
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.
