AnyEvent::XMPP::IM::Message(3) Instant message

SYNOPSIS


use AnyEvent::XMPP::IM::Message;
my $con = AnyEvent::XMPP::IM::Connection->new (...);
AnyEvent::XMPP::IM::Message->new (
body => "Hello there!",
to => "[email protected]"
)->send ($con);

DESCRIPTION

This module represents an instant message. It's mostly a shortlived object and acts as wrapper object around the XML stuff that is happening under the hood.

A AnyEvent::XMPP::IM::Message object overloads the stringification operation. The string represenation of this object is the return value of the "any_body" method.

AnyEvent::XMPP::IM::Message is derived from AnyEvent::XMPP::IM::Delayed, use the interface described there to find out whether this message was delayed.

METHODS

new (%args)
This method creates a new instance of a AnyEvent::XMPP::IM::Message.

%args is the argument hash. All arguments to "new" are optional.

These are the possible keys:

connection => $connection
This is the AnyEvent::XMPP::IM::Connection object that will be used to send this message when the "send" method is called.
to => $jid
This is the destination JID of this message. $jid should be full if this message is send within a conversation 'context', for example when replying to a previous message.

Replies can also be generated by the "make_reply" method, see also the "from" argument below.

from => $jid
This is the source JID of this message, it's mainly used by the "make_reply" method.
lang => $lang
This is the default language that will be used to tag the values passed in the "body" and "subject" argument to "new".
body => $body
This is the text $body of the message either with the language tag from the "lang" attached or without any language tag.

If you want to attach multiple bodies with different languages use the "add_body" method.

subject => $subject
This is the $subject of the message either with the language tag from the "lang" attached or without any language tag.

If you want to attach the subject with a different language use the "add_subject" method.

type => $type
This field sets the type of the message. See also the type method below.

The default value for $type is 'normal'.

id ([$msg_id])
This method returns the ID of this message. If $msg_id is not undef it will replace the current message id.
from ([$jid])
This method returns the source JID of this message. If $jid is not undef it will replace the current source address.
to ([$jid])
This method returns the destination JID of this message. If $jid is not undef it will replace the current destination address.
make_reply ([$msg])
This method returns a new instance of AnyEvent::XMPP::IM::Message. The destination address, connection and type of the returned message object will be set.

If $msg is defined and an instance of AnyEvent::XMPP::IM::Message the destination address, connection and type of $msg will be changed and this method will not return a new instance of AnyEvent::XMPP::IM::Message.

is_connected ()
This method returns 1 when the message is ``connected''. That means: It returns 1 when you can call the "send" method without a connection argument. (It will also return only 1 when the connection that is referenced by this message is still connected).
send ([$connection])
This method send this message. If $connection is defined it will set the connection of this message object before it is send.
type ([$type])
This method returns the type of the message, which is either undefined or one of the following values: 

   'chat', 'error', 'groupchat', 'headline', 'normal'

If the $type argument is defined it will set the type of this message.

thread ([$thread])
This method returns the thread id of this message, which might be undefined.

If you want to set the threadid simply pass the $thread argument.

lang ([$lang])
This returns the default language tag of this message, which can be undefined.

To set the language tag pass the $lang argument, which should be the new default language tag.

If you do not want to specify any language pass the empty string as language tag.

subject ([$lang])
This method returns the subject of this message. If the $lang argument is defined a subject of that language will be returned or undef. If the $lang argument is undefined this method will return either the subject in the default language.
any_subject ([$lang])
This method will try to find any subject on the message with the following try order of languagetags: 

  1. $lang argument if one passed
  2. default language
  3. subject without any language tag
  4. subject with the 'en' language tag
  5. any subject from any language
add_subject ($subject, [$lang], [$subject2, $lang2, ...])
This method adds the subject $subject with the optional language tag $lang to this message. If no $lang argument is passed the default language for this message will be used.

Further subject => lang pairs can passed to this function like this: 

   $msg->add_subject ('foobar' => undef, "barfooo" => "de");
subjects
This method returns a list of key value pairs with the language tag as key and the subject as value.

The subject which has the empty string as key has no language attached.

body ([$lang])
This method returns the body of this message. If the $lang argument is defined a body of that language will be returned or undef. If the $lang argument is undefined this method will return either the body in the default language.
any_body ([$lang])
This method will try to find any body on the message with the following try order of languagetags: 

  1. $lang argument if one passed
  2. default language
  3. body without any language tag
  4. body with the 'en' language tag
  5. any body from any language
add_body ($body, [$lang], [$body2, $lang2, ...])
This method adds the body $body with the optional language tag $lang to this message. If no $lang argument is passed the default language for this message will be used.

Further body => lang pairs can passed to this function like this: 

   $msg->add_body ('foobar' => undef, "barfooo" => "de");
bodies
This method returns a list of key value pairs with the language tag as key and the body as value.

The body which has the empty string as key has no language attached.

append_creation ($create_cb)
This method allows the user to append custom XML stuff to the message when it is sent. This is an example: 

   my $msg =
      AnyEvent::XMPP::IM::Message->new (
         body => "Test!",
         to => "[email protected]",
      );
   $msg->append_creation (sub {
      my ($w) = @_;
      $w->startTag (['http://test.namespace','test']);
      $w->characters ("TEST");
      $w->endTag;
   });
   $msg->send ($con);

This should send a message stanza similar to this:
