Description

TpMessage represent a message send or received using the Message interface.

Details

TpMessage

typedef struct _TpMessage TpMessage;

Opaque structure representing a message in the Telepathy messages interface (an array of at least one mapping from string to variant, where the first mapping contains message headers and subsequent mappings contain the message body).

This base class provides convenience API for most of the common keys that can appear in the header. One notable exception is the sender of the message. Inside a connection manager, messages are represented by the TpCMMessage subclass, and you should use tp_cm_message_get_sender(). When composing a message in a client using TpClientMessage, messages do not have an explicit sender (the sender is automatically the local user). When a client sees a sent or received message signalled by the connection manager (represented by TpSignalledMessage), the message's sender (if any) can be accessed with tp_signalled_message_get_sender().

self :

a message

part :

a part number

Returns :

the GHashTable used to implement the given part, or NULL if the part number is out of range. The hash table is only valid as long as the message is valid and the part is not deleted. [transfer none][element-type utf8 GObject.Value]

Since 0.7.21


tp_message_to_text ()

gchar *             tp_message_to_text                  (TpMessage *message,

Concatene all the text parts contained in message.

message :

a TpMessage

out_flags :

(out) : if not NULL, the TpChannelTextMessageFlags of message

Returns :

a newly allocated string containing the text content of message. [transfer full]

Since 0.13.9


tp_message_get_message_type ()

TpChannelTextMessageType tp_message_get_message_type    (TpMessage *self);

self :

a message

Returns :

the type of this message

Since 0.13.10


tp_message_get_received_timestamp ()

gint64              tp_message_get_received_timestamp   (TpMessage *self);

Return when this message was received locally, as a number of seconds since the beginning of 1970 in the UTC timezone (the same representation used by g_date_time_new_from_unix_utc(), for instance), or 0 if not known.

self :

a message

Returns :

a Unix timestamp, or 0

Since 0.13.9


tp_message_get_sent_timestamp ()

gint64              tp_message_get_sent_timestamp       (TpMessage *self);

Return when this message was sent, as a number of seconds since the beginning of 1970 in the UTC timezone (the same representation used by g_date_time_new_from_unix_utc(), for instance), or 0 if not known.

If this protocol does not track the time at which the message was initially sent, this timestamp might be approximated by using the time at which it arrived at a central server.

self :

a message

Returns :

a Unix timestamp, or 0

Since 0.13.9


tp_message_get_specific_to_interface ()

const gchar *       tp_message_get_specific_to_interface
                                                        (TpMessage *self);

If this message is specific to a particular D-Bus interface and should be ignored by clients without knowledge of that interface, return the name of the interface.

If this message is an ordinary message or delivery report, return NULL.

self :

a message

Returns :

a D-Bus interface name, or NULL for ordinary messages and delivery reports. [transfer none]

Since 0.13.9


tp_message_get_supersedes ()

const gchar *       tp_message_get_supersedes           (TpMessage *self);

If this message replaces a previous message, return the value of tp_message_get_token() for that previous message. Otherwise, return NULL.

For instance, a user interface could replace the superseded message with this message, or grey out the superseded message.

self :

a message

Returns :

a non-empty opaque identifier, or NULL if none. [transfer none]

Since 0.13.9


tp_message_get_token ()

const gchar *       tp_message_get_token                (TpMessage *self);

Return this message's identifier in the underlying protocol. This is not guaranteed to be unique, even within the scope of a single channel or contact: the only guarantee made is that two messages with different non-empty tokens are different messages.

If there is no suitable token, return NULL.

self :

a message

Returns :

a non-empty opaque identifier, or NULL if none. [transfer none]

Since 0.13.9


tp_message_is_delivery_report ()

gboolean            tp_message_is_delivery_report       (TpMessage *self);

If this message is a delivery report indicating success or failure of delivering a message, return TRUE.

self :

a message

Returns :

TRUE if this is a delivery report

Since 0.13.9


tp_message_is_rescued ()

gboolean            tp_message_is_rescued               (TpMessage *self);

Returns TRUE if this incoming message has been seen in a previous channel during the lifetime of the Connection, but had not been acknowledged when that channel closed, causing an identical channel (in which the message now appears) to open.

Loggers should check this flag to avoid duplicating messages, for instance.

self :

a message

Returns :

TRUE if this message was seen in a previous Channel on this Connection

Since 0.13.9


tp_message_is_scrollback ()

gboolean            tp_message_is_scrollback            (TpMessage *self);

self :

a message

Returns :

TRUE if this message is part of a replay of message history, for instance in an XMPP chatroom.

Since 0.13.9


tp_message_get_pending_message_id ()

guint32             tp_message_get_pending_message_id   (TpMessage *self,
                                                         gboolean *valid);

Return the incoming message ID of self. Only incoming messages have such ID, for outgoing ones this function returns 0 and set valid to FALSE.

self :

a message

valid :

either NULL, or a location in which to store TRUE if self contains a pending message ID. [out]

Returns :

the incoming message ID.

Since 0.15.3


tp_message_is_mutable ()

gboolean            tp_message_is_mutable               (TpMessage *self);
