## 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.

  ContactManager::contactsForUris(), vcardAddresses()

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

Return whether the avatar token of this contact is known.

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.

This method requires Contact::FeatureAvatarToken to be ready.

Returns:
  The avatar token.

See also:

void Tp::Contact::requestAvatarData | ( |  | ) |

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()

Return the capabilities for this contact.

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.

This method requires Contact::FeatureCapabilities to be ready.

Returns:
  An object representing the contact capabilities.

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.

Returns:
  A PendingContactInfo, which will emit PendingContactInfo::finished when the information has been retrieved or an error occurred.

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

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