Use an empty JID to create a broadcast packet. status  An optional status message (e.g. "gone fishing"). priority  An optional presence priority. Legal range is between -128 and +127.

void addStatus (  const std::string &  status, const std::string &  lang = EmptyString )  [inline]

Adds a (possibly translated) status message. Parameters: status  The status message. lang  The language identifier for the desired language. It must conform to section 2.12 of the XML specification and RFC 3066. Definition at line 117 of file presence.h.

const Capabilities * capabilities (   )  const

A convenience function returning the stanza's Capabilities, if any. May be 0. Returns: A pointer to a Capabilities object, or 0. Definition at line 103 of file presence.cpp.

PresenceType presence (   )  const [inline]

Returns the presence's type. Returns: The presence's type. Definition at line 89 of file presence.h.

int priority (   )  const [inline]

Returns the presence priority in the legal range: -128 to +127. Returns: The priority information contained in the stanza, defaults to 0. Definition at line 131 of file presence.h.

void resetStatus (   )

Resets the default status message as well as all language-specific ones. Definition at line 86 of file presence.cpp.

void setPresence (  PresenceType  type  )  [inline]

Sets the presence type. Parameters: type  The presence type. Definition at line 95 of file presence.h.

void setPriority (  int  priority  )

Sets the priority. Legal range: -128 to +127. Parameters: priority  The priority to set. Definition at line 93 of file presence.cpp.

const std::string status (  const std::string &  lang = "default"  )  const [inline]

Returns the status text of a presence stanza for the given language if available. If the requested language is not available, the default status text (without a xml:lang attribute) will be returned. Parameters: lang  The language identifier for the desired language. It must conform to section 2.12 of the XML specification and RFC 3066. If empty, the default body will be returned, if any. Returns: The status text set by the sender. Definition at line 106 of file presence.h.

PresenceType subtype (   )  const [inline]

Returns the presence's type. Returns: The presence's type. Definition at line 76 of file presence.h.

Tag * tag (   )  const [virtual]

Creates a Tag representation of the Stanza. The Tag is completely independent of the Stanza and will not be updated when the Stanza is modified. Returns: A pointer to a Tag representation. It is the job of the caller to delete the Tag. Implements Stanza. Definition at line 108 of file presence.cpp.
