## Detailed Description

The Contact class represents a Telepathy contact.

The accessor functions on this object (id(), alias(), and so on) don't make any D-Bus calls; instead, they return/use values cached from a previous introspection run. The introspection process populates their values in the most efficient way possible based on what the service implements.

To avoid unnecessary D-Bus traffic, some accessors only return valid information after specific features have been enabled. For instance, to retrieve the contact avatar token, it is necessary to enable the feature Contact::FeatureAvatarToken. See the individual methods descriptions for more details.

Contact features can be enabled by constructing a ContactFactory and enabling the desired features, and passing it to AccountManager, Account or ClientRegistrar when creating them as appropriate. However, if a particular feature is only ever used in a specific circumstance, such as an user opening some settings dialog separate from the general view of the application, features can be later enabled as needed by calling ContactManager::upgradeContacts() with the additional features, and waiting for the resulting PendingOperation to finish.

As an addition to accessors, signals are emitted to indicate that properties have changed, for example aliasChanged(), avatarTokenChanged(), etc.

This method requires Contact::FeatureAvatarToken to be ready.

Returns
  `true` if the avatar token is known, `false` otherwise.

See Also
  avatarToken()

QString Tp::Contact::avatarToken | ( |  | ) | const

Return the avatar token for this contact.

Change notification is via the avatarTokenChanged() signal.

Start a request to retrieve the avatar for this contact.

Force the request of the avatar data. This method returns directly, emitting avatarTokenChanged() and avatarDataChanged() signals once the token and data are fetched from the server.

This is only useful if the avatar token is unknown; see isAvatarTokenKnown(). It happens in the case of offline XMPP contacts, because the server does not send the token for them and an explicit request of the avatar data is needed.

This method requires Contact::FeatureAvatarData to be ready.

See Also
  avatarData(), avatarDataChanged(), avatarToken(), avatarTokenChanged()

Presence Tp::Contact::presence | ( |  | ) | const

User interfaces can use this information to show or hide UI components.

If ContactManager::supportedFeatures() contains Contact::FeatureCapabilities, the returned object will be a ContactCapabilities object, where CapabilitiesBase::isSpecificToContact() will be `true`; if that feature isn't present, this returned object is the subset of Contact::manager()::connection()::capabilities() and CapabilitiesBase::isSpecificToContact() will be `false`.

Change notification is via the capabilitiesChanged() signal.

Returns
  The contact location as a LocationInfo object.

bool Tp::Contact::isContactInfoKnown | ( |  | ) | const

Return whether the info card for this contact has been received.

With some protocols (notably XMPP) information is not pushed from the server and must be requested explicitely using refreshInfo() or requestInfo(). This method can be used to know if the information is received from the server or if an explicit request is needed.

Returns
  `true` if the information is known; `false` otherwise.

Contact::InfoFields Tp::Contact::infoFields | ( |  | ) | const

Note that this method only return cached information. In order to refresh the information use refreshInfo().

Change notification is via the infoFieldsChanged() signal.

This method requires Contact::FeatureInfo to be ready.

Returns
  The contact info as a Contact::InfoFields object.

bool Tp::Contact::isSubscriptionStateKnown | ( |  | ) | const

Return whether the presence subscription state of this contact is known.

Returns
  `true` if the presence subscription state is known, `false` otherwise.

See Also
  blockAndReportAbuse(), unblock()

See Also
  groups(), addToGroup()

QStringList Tp::Contact::clientTypes | ( |  | ) | const

Return the client types of this contact, if known.

Client types are represented using the values documented by the XMPP registrar, with some additional types. A contact can set one or more client types, or can simply advertise itself as unknown - in this case, an empty list is returned.

This method returns cached information and is more appropriate for "lazy" client type finding, for instance displaying the client types (if available) of everyone in your contact list. For getting latest up-to-date information from the server you should use requestClientTypes() instead.

This method requires FeatureClientTypes to be ready.

Returns
  A list of the client types advertised by this contact.

See Also
  requestClientTypes(), clientTypesChanged()

PendingStringList * Tp::Contact::requestClientTypes | ( |  | ) |

Return the current client types of the given contact.

If necessary, this method will make a request to the server for up-to-date information and wait for a reply. Therefore, this method is more appropriate for use in a "Contact Information..." dialog; it can be used to show progress information (while waiting for the method to return), and can distinguish between various error conditions.

This method requires FeatureClientTypes to be ready.

Returns
  A list of the client types advertised by this contact.
