Mail::Box::Message - manage one message within a mail-folder


NAME

Mail::Box::Message - manage one message within a mail-folder


INHERITANCE

 Mail::Box::Message
   is a Mail::Message
   is a Mail::Reporter
 Mail::Box::Message is extended by
   Mail::Box::Dir::Message
   Mail::Box::File::Message
   Mail::Box::Message::Destructed
   Mail::Box::Net::Message


SYNOPSIS

 # Usually these message objects are created indirectly
 use Mail::Box::Manager;
 my $manager = Mail::Box::Manager->new;
 my $folder  = $manager->open(folder => 'Mail/Drafts');
 my $msg     = $folder->message(1);
 $msg->delete;
 $msg->size;   # and much more


DESCRIPTION

These pages do only describe methods which relate to folders. If you access the knowledge of a message, then read Mail::Message.

During its life, a message will pass through certain stages. These stages were introduced to reduce the access-time to the folder. Changing from stage, the message's body and head objects may change.

. body OBJECT

. body_type CODE|CLASS

If the body of a message is used delay-loaded, the message must what type of message to become when it finally gets parsed. The folder which is delaying the load must specify the algorithm to determine that type.

. deleted BOOLEAN

. field_type CLASS

. folder FOLDER

The folder where this message appeared in. The argument is an instance of (a sub-class of) a Mail::Box.

. head OBJECT

. head_type CLASS

. labels ARRAY|HASH

. log LEVEL

. messageId STRING

. modified BOOLEAN

. size INTEGER

The size of the message, which includes head and body, but without the message separators which may be used by the folder type.

. trace LEVEL

. trusted BOOLEAN

The message

$obj->container

See The message in the Mail::Message manpage

$obj->copyTo(FOLDER, OPTIONS)

Copy the message to the indicated opened FOLDER, without deleting the original. The coerced message (the clone in the destination folder) is returned.

 Option        Defined in       Default
 shallow                        <false>
 shallow_body                   <false>
 shallow_head                   <false>
 share                          <false>

. shallow BOOLEAN

Used for clone(shallow).

. shallow_body BOOLEAN

Used for clone(shallow_body).

. shallow_head BOOLEAN

Used for clone(shallow_head).

. share BOOLEAN

Try to share the physical storage of the message between the two folders. Sometimes, they even may be of different types. When not possible, this options will be silently ignored.

Example:

 my $draft = $mgr->open(folder => 'Draft');
 $message->copyTo($draft, share => 1);

$obj->folder([FOLDER])

In with folder did we detect this message/dummy? This is a reference to the folder-object.

$obj->isDummy

See The message in the Mail::Message manpage

$obj->isPart

See The message in the Mail::Message manpage

$obj->messageId

See The message in the Mail::Message manpage

$obj->moveTo(FOLDER, OPTIONS)

Move the message from this folder to the FOLDER specified. This will create a copy using clone() first. Then, this original message is flagged to get deleted. So until the source folder is closed, two copies of the message may stay in memory.

The newly created message clone (part of the destination folder) is returned. All OPTIONS are passed to copyTo()

 Option        Defined in       Default                          
 shallow_body                   <undef>                          
 share                          <true unless shallow_body exists>

. shallow_body BOOLEAN

Only create a shallow body, which means that the header can not be reused. A message can therefore not be shared in storage unless explicitly stated.

. share BOOLEAN

When there is a chance that the original message can be undeleted, then this must be set to false. Otherwise a shallow clone will be made, which will share the header which can be modified in the undeleted message.

Example: of moving a message

 my $t = $msg->moveTo('trash');

is equivalent to

 my $t = $msg->copyTo('trash', share => 1);
 $msg->delete;

$obj->readBody(PARSER, HEAD [, BODYTYPE])

Read the body of one message. The PARSER gives access to the folder file. The HEAD has been read with readHead(). The optional BODYTYPE supplies the class name of the body to be created, or a code reference to a routine which can produce a body type based on the head (passed as first argument).

By default, the BODYTYPE will call Mail::Box::determineBodyType() where the message will be added to.

Cleanup

$obj->DESTROY

See Cleanup in the Mail::Message manpage

$obj->destruct

Removes most of the memory occupied by the message by detaching the header and body. Then, the object changes into a Mail::Box::Message::Destructed which will catch all attempts to access the header and body. Be careful with the usage of this method.

$obj->inGlobalDestruction

DIAGNOSTICS

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: 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: 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: forwardAttach requires a preamble object

Error: forwardEncapsulate requires a preamble object

Error: no rebuild rule $name defined.
