Mail::Box::Message::DeUsercContributed Perl DMail::Box::Message::Destructed(3)NAMEMail::Box::Message::Destructed - a destructed message
INHERITANCEMail::Box::Message::Destructed
is a Mail::Box::Message
is a Mail::Message
is a Mail::Reporter
SYNOPSIS
$folder->message(3)->destruct;
DESCRIPTION
When a message folder is read, each message will be parsed into Perl
structures. Especially the header structure can consume a huge amount
of memory (message bodies can be moved to external temporary files).
Destructed messages have forcefully cleaned-up all header and body
information, and are therefore much smaller. Some useful information
is still in the object.
BE WARNED: once a message is destructed, it cannot be revived.
Destructing enforces irreversable deletion from the folder. If you
have a folder opened for read-only, the message will stay in that
folder, but otherwise it may be deleted.
METHODS

DETAILSDIAGNOSTICS
Error: Cannot coerce a (class) into destruction
Only real Mail::Box::Message objects can get destructed into
Mail::Box::Message::Destructed objects. Mail::Message free their
memory immediately when the last reference is lost.
Error: Cannot include forward source as $include.
Unknown alternative for the forward(include). Valid choices are
"NO", "INLINE", "ATTACH", and "ENCAPSULATE".
Error: Cannot include reply source as $include.
Unknown alternative for the "include" option of reply(). Valid
choices are "NO", "INLINE", and "ATTACH".
Error: Destructed message has no labels except 'deleted'
Error: Destructed messages can not be undeleted
Once a message is destructed, it can not be revived. Destruction
is an optimization in memory usage: if you need an undelete
functionality, then you can not use Mail::Box::Message::destruct().
Error: Method bounce requires To, Cc, or Bcc
The message bounce() method forwards a received message off to
someone else without modification; you must specified it's new
destination. If you have the urge not to specify any destination,
you probably are looking for reply(). When you wish to modify the
content, use forward().
Error: Method forwardAttach requires a preamble
Error: Method forwardEncapsulate requires a preamble
Error: No address to create forwarded to.
If a forward message is created, a destination address must be
specified.
Error: No default mailer found to send message.
The message send() mechanism had not enough information to
automatically find a mail transfer agent to sent this message.
Specify a mailer explicitly using the "via" options.
Error: No rebuild rule $name defined.
Error: Only build() Mail::Message's; they are not in a folder yet
You may wish to construct a message to be stored in a some kind of
folder, but you need to do that in two steps. First, create a
normal Mail::Message, and then add it to the folder. During this
Mail::Box::addMessage() process, the message will get coerce()-d
into the right message type, adding storage information and the
like.
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.
Error: You cannot instantiate a destructed message
You cannot instantiate a destructed message object directly.
Destruction is done by calling Mail::Box::Message::destruct() on
any existing folder message.
Error: You cannot take the head/body of a destructed message
The message originated from a folder, but its memory has been
freed-up forcefully by means of Mail::Box::Message::destruct().
Apparently, your program still tries to get to the header or body
data after this destruction, which is not possible.
