## Description

TpContact objects represent the contacts on a particular TpConnection.

## Details

### TpContact

    typedef struct _TpContact TpContact;

An object representing a contact on a TpConnection.

Contact objects support tracking a number of attributes of contacts, as described by the TpContactFeature flags. Features can be specified when instantiating contact objects (with `tp_connection_get_contacts_by_id()` or `tp_connection_get_contacts_by_handle()`), or added to an existing contact object with `tp_connection_upgrade_contacts()`. For example, a client wishing to keep track of a contact's alias would set TP_CONTACT_FEATURE_ALIAS, and then listen for the "notify::alias" signal, emitted whenever the "alias" property changes.

Note that releasing a TpContact object might release handle references held by calling `tp_cli_connection_call_request_handles()`, `tp_cli_connection_run_request_handles()`, `tp_cli_connection_call_hold_handles()`, `tp_cli_connection_run_hold_handles()`, `tp_cli_connection_interface_contacts_call_get_contact_attributes()` or `tp_cli_connection_interface_contacts_run_get_contact_attributes()` directly. Those functions should be avoided in favour of using TpContact, `tp_connection_hold_handles()`, `tp_connection_request_handles()` and `tp_connection_get_contact_attributes()`.

Since 0.7.18

### enum TpContactFeature

    typedef enum {
        TP_CONTACT_FEATURE_ALIAS,
        TP_CONTACT_FEATURE_AVATAR_TOKEN,
        TP_CONTACT_FEATURE_PRESENCE,
        TP_CONTACT_FEATURE_LOCATION,
        TP_CONTACT_FEATURE_CAPABILITIES,
        TP_CONTACT_FEATURE_AVATAR_DATA,
        TP_CONTACT_FEATURE_CONTACT_INFO,
        TP_CONTACT_FEATURE_CLIENT_TYPES,
        TP_CONTACT_FEATURE_SUBSCRIPTION_STATES,
        TP_CONTACT_FEATURE_CONTACT_GROUPS,
        TP_CONTACT_FEATURE_CONTACT_BLOCKING,
    } TpContactFeature;

Enumeration representing the features a TpContact can optionally support. When requesting a TpContact, library users specify the desired features; the TpContact code will only initialize state for those features, to avoid unwanted D-Bus round-trips and signal connections.

Since 0.11.5, there is a corresponding GEnumClass type, `TP_TYPE_CONTACT_FEATURE`.

`TP_CONTACT_FEATURE_ALIAS` | "alias"
`TP_CONTACT_FEATURE_AVATAR_TOKEN` | "avatar-token"
`TP_CONTACT_FEATURE_PRESENCE` | "presence-type", "presence-status" and "presence-message"
`TP_CONTACT_FEATURE_LOCATION` | "location" (available since 0.11.1) and "location-vardict" (since 0.19.10)
`TP_CONTACT_FEATURE_CAPABILITIES` | "capabilities" (available since 0.11.3)
`TP_CONTACT_FEATURE_AVATAR_DATA` | "avatar-file" and "avatar-mime-type". Implies `TP_CONTACT_FEATURE_AVATAR_TOKEN` (available since 0.11.6)
`TP_CONTACT_FEATURE_CONTACT_INFO` | "contact-info" (available since 0.11.7)
`TP_CONTACT_FEATURE_CLIENT_TYPES` | "client-types" (available since 0.13.1)
`TP_CONTACT_FEATURE_SUBSCRIPTION_STATES` | "subscribe-state", "publish-state" and "publish-request". Require a Connection implementing the `TP_IFACE_CONNECTION_INTERFACE_CONTACT_LIST` interface. (available since 0.13.12)
`TP_CONTACT_FEATURE_CONTACT_GROUPS` | "contact-groups" (available since 0.13.14)
`TP_CONTACT_FEATURE_CONTACT_BLOCKING` | "is-blocked". Require Connection implementing the `TP_IFACE_CONNECTION_INTERFACE_CONTACT_BLOCKING` interface. (available since 0.17.0)

Since 0.7.18

### TP_CONTACT_FEATURE_INVALID

    #define TP_CONTACT_FEATURE_INVALID ((TpContactFeature) -1)

An invalid TpContactFeature. Used as list termination. See for example `tp_simple_client_factory_add_contact_features_varargs()`.

Since 0.15.5

### NUM_TP_CONTACT_FEATURES

    #define NUM_TP_CONTACT_FEATURES TP_NUM_CONTACT_FEATURES

1 higher than the highest TpContactFeature supported by this version of telepathy-glib. Use `TP_NUM_CONTACT_FEATURES` in new code.

Since 0.7.18

### TP_NUM_CONTACT_FEATURES

    #define TP_NUM_CONTACT_FEATURES (TP_CONTACT_FEATURE_CONTACT_BLOCKING + 1)

1 higher than the highest TpContactFeature supported by this version of telepathy-glib.

Since 0.19.0

### TP_TYPE_CONTACT_FEATURE

    #define TP_TYPE_CONTACT_FEATURE (tp_contact_feature_get_type ())

The GEnumClass type of a TpContactFeature.

Since 0.11.5

### TpConnectionContactsByHandleCb ()

    void                (*TpConnectionContactsByHandleCb)   (TpConnection *connection,
                                                             guint n_contacts,
                                                             TpContact * const *contacts,
                                                             guint n_failed,
                                                             const TpHandle *failed,
                                                             const GError *error,
                                                             gpointer user_data,
                                                             GObject *weak_object);

### Warning

`TpConnectionContactsByHandleCb` is deprecated and should not be used in newly-written code.

Signature of a callback used to receive the result of `tp_connection_get_contacts_by_handle()`.

If an unrecoverable error occurs (for instance, if `connection` becomes disconnected) the whole operation fails, and no contacts or invalid handles are returned.

If some or even all of the `handles` passed to `tp_connection_get_contacts_by_handle()` were not valid, this is not considered to be a failure. `error` will be `NULL` in this situation, `contacts` will contain contact objects for those handles that were valid (possibly none of them), and `invalid` will contain the handles that were not valid.

`connection` : | The connection
`n_contacts` : | The number of TpContact objects successfully created (one per valid handle), or 0 on unrecoverable errors
`contacts` : | An array of `n_contacts` TpContact objects (this callback is not given a reference to any of these objects, and must call `g_object_ref()` on any that it will keep), or `NULL` on unrecoverable errors. [array length=n_contacts]
`n_failed` : | The number of invalid handles that were passed to `tp_connection_get_contacts_by_handle()` (or on unrecoverable errors, the total number of handles that were given)
`failed` : | An array of `n_failed` handles that were passed to `tp_connection_get_contacts_by_handle()` but turned out to be invalid (or on unrecoverable errors, all the handles that were given). [array length=n_failed]
`error` : | `NULL` on success, or an unrecoverable error that caused everything to fail
`user_data` : | the `user_data` that was passed to `tp_connection_get_contacts_by_handle()`
`weak_object` : | the `weak_object` that was passed to `tp_connection_get_contacts_by_handle()`

Since 0.7.18

### tp_connection_dup_contact_if_possible ()

    TpContact *         tp_connection_dup_contact_if_possible
                                                            (TpConnection *connection,
                                                             TpHandle handle,
                                                             const gchar *identifier);

Try to return an existing contact object or create a new contact object immediately.

If `tp_connection_has_immortal_handles()` would return `TRUE` and `identifier` is non-`NULL`, this function always succeeds.

On connections without immortal handles, it is not possible to guarantee that `handle` remains valid without making asynchronous D-Bus calls, so it might be necessary to delay processing of messages or other events until a TpContact can be constructed asynchronously, for instance by using `tp_connection_get_contacts_by_id()`.

Similarly, if `identifier` is `NULL`, it might not be possible to find the identifier for `handle` without making asynchronous D-Bus calls, so it might be necessary to delay processing of messages or other events until a TpContact can be constructed asynchronously, for instance by using `tp_connection_get_contacts_by_handle()`.

`connection` : | a connection
`handle` : | a handle of type `TP_HANDLE_TYPE_CONTACT`
`identifier` : | the normalized identifier (XMPP JID, etc.) corresponding to `handle`, or `NULL` if not known. [transfer none]
Returns : | a contact or `NULL`. [transfer full]

Since 0.13.9

### tp_connection_get_contacts_by_handle ()

### Warning

`tp_connection_get_contacts_by_handle` is deprecated and should not be used in newly-written code. Use `tp_simple_client_factory_ensure_contact()` instead.

Create a number of TpContact objects and make asynchronous method calls to hold their handles and ensure that all the features specified in `features` are ready for use (if they are supported at all).

It is not an error to put features in `features` even if the connection manager doesn't support them - users of this method should have a static list of features they would like to use if possible, and use it for all connection managers.

`self` : | A connection, which must have the `TP_CONNECTION_FEATURE_CONNECTED` feature prepared
`n_handles` : | The number of handles in `handles` (must be at least 1)
`handles` : | An array of handles of type `TP_HANDLE_TYPE_CONTACT` representing the desired contacts. [array length=n_handles][element-type uint]
`n_features` : | The number of features in `features` (may be 0)
`features` : | An array of features that must be ready for use (if supported) before the callback is called (may be `NULL` if `n_features` is 0). [array length=n_features][allow-none][element-type uint]
`callback` : | A user callback to call when the contacts are ready
`user_data` : | Data to pass to the callback
`destroy` : | Called to destroy `user_data` either after `callback` has been called, or if the operation is cancelled
`weak_object` : | An object to pass to the callback, which will be weakly referenced; if this object is destroyed, the operation will be cancelled. [allow-none]

Signature of a callback used to receive the result of `tp_connection_get_contacts_by_id()`.

`requested_ids` contains the IDs that were converted to handles successfully. The normalized form of requested_ids[i] is tp_contact_get_identifier (contacts[i]).

If some or even all of the `ids` passed to `tp_connection_get_contacts_by_id()` were not valid, this is not considered to be a fatal error. `error` will be `NULL` in this situation, `contacts` will contain contact objects for those IDs that were valid (it may be empty), and `failed_id_errors` will map the IDs that were not valid to a corresponding GError (if the connection manager complies with the Telepathy spec, it will have domain `TP_ERROR` and code `TP_ERROR_INVALID_HANDLE`).

If an unrecoverable error occurs (for instance, if `connection` becomes disconnected) the whole operation fails, and no contacts or requested IDs are returned. `failed_id_errors` will contain all the IDs that were requested, mapped to a corresponding GError (either one indicating that the ID was invalid, if that was determined before the fatal error occurred, or a copy of `error`).

`tp_contact_get_contact_info` is deprecated and should not be used in newly-written code. Since 0.19.9. New code should use `tp_contact_dup_contact_info()` instead.

Returns a newly allocated GList of contact's vCard fields. The list must be freed with `g_list_free()` after used.

Requests an asynchronous request of the contact info of `self`. When the operation is finished, `callback` will be called. You can then call `tp_contact_request_contact_info_finish()` to get the result of the operation.

If the operation is successful, the "contact-info" property will be updated (emitting "notify::contact-info" signal) before `callback` is called. That means you can call `tp_contact_get_contact_info()` to get the new vCard inside `callback`.

Note that requesting the vCard from the network can take significant time, so a bigger timeout is set on the underlying D-Bus call. `cancellable` can be cancelled to free resources used in the D-Bus call if the caller is no longer interested in the vCard.

If `TP_CONTACT_FEATURE_CONTACT_INFO` is not yet set on `self`, it will be set before its property gets updated and `callback` is called.

If "publish-state" is set to `TP_SUBSCRIPTION_STATE_ASK`, return the message that this remote contact sent when they requested permission to see the local user's presence, an empty string ("") otherwise. This remains valid until the main loop is re-entered; if the caller requires a string that will persist for longer than that, it must be copied with `g_strdup()`.

This is set to `NULL` until `TP_CONTACT_FEATURE_SUBSCRIPTION_STATES` has been prepared, and it is guaranteed to be non-`NULL` afterward.

Add `self` to the given groups (creating new groups if necessary), and remove it from all other groups. If the user is removed from a group of which they were the only member, the group MAY be removed automatically. You can then call `tp_contact_set_contact_groups_finish()` to get the result of the operation.

If the operation is successful and `TP_CONTACT_FEATURE_CONTACT_GROUPS` is prepared, the "contact-groups" property will be updated (emitting "notify::contact-groups" signal) and "contact-groups-changed" signal will be emitted before `callback` is called. That means you can call `tp_contact_get_contact_groups()` to get the new contact groups inside `callback`.

`self` : | a TpContact
`n_groups` : | the number of groups, or -1 if `groups` is `NULL`-terminated
`groups` : | the set of groups which the contact should be in (may be `NULL` if `n_groups` is 0). [array length=n_groups][element-type utf8][allow-none]
`callback` : | a callback to call when the request is satisfied
`user_data` : | data to pass to `callback`

## Property Details

### The `"alias"` property

      "alias"                    gchar*                : Read

The contact's alias if available, falling back to their "identifier" if no alias is available or if the TpContact has not been set up to track `TP_CONTACT_FEATURE_ALIAS`.

This alias may have been supplied by the contact themselves, or by the local user, so it does not necessarily unambiguously identify the contact. However, it is suitable for use as a main "display name" for the contact.

This is never `NULL` for contact objects that are visible to library-user code.

Default value: NULL

### The `"avatar-file"` property

      "avatar-file"              GFile*                : Read

GFile to the latest cached avatar image, or `NULL` if this contact has no avatar, or if the avatar data is not yet retrieved.

When "avatar-token" changes, this property is not updated immediately, but will be updated when the new avatar data is retrieved and stored in cache. Until then, the file will keep its old value of the latest cached avatar image.

This is set to `NULL` if `TP_CONTACT_FEATURE_AVATAR_DATA` is not set on this contact. Note that setting `TP_CONTACT_FEATURE_AVATAR_DATA` will also implicitly set `TP_CONTACT_FEATURE_AVATAR_TOKEN`.

Since 0.11.6

### The `"avatar-mime-type"` property

      "avatar-mime-type"         gchar*                : Read

MIME type of the latest cached avatar image, or `NULL` if this contact has no avatar, or if the avatar data is not yet retrieved.

This is always the MIME type of the image given by "avatar-file".

Default value: NULL

Since 0.11.6

### The `"avatar-token"` property

      "avatar-token"             gchar*                : Read

An opaque string representing state of the contact's avatar (depending on the protocol, this might be a hash, a timestamp or something else), or an empty string if there is no avatar.

This may be `NULL` if it is not known whether this contact has an avatar or not (either for network protocol reasons, or because this TpContact has not been set up to track `TP_CONTACT_FEATURE_AVATAR_TOKEN`).

Default value: NULL

### The `"capabilities"` property

      "capabilities"             TpCapabilities*       : Read

The capabilities supported by this contact. If the underlying Connection doesn't support the ContactCapabilities interface, this property will contain the capabilities supported by the connection. Use `tp_capabilities_is_specific_to_contact()` to check if the capabilities are specific to this TpContact or not.

This may be `NULL` if this TpContact object has not been set up to track `TP_CONTACT_FEATURE_CAPABILITIES`.

Since 0.11.3

### The `"client-types"` property

      "client-types"             GStrv                 : Read

A GStrv containing the client types of this contact.

This is set to `NULL` if `TP_CONTACT_FEATURE_CLIENT_TYPES` is not set on this contact; it may also be `NULL` if that feature is prepared, but the contact's client types are unknown.

Since 0.13.1

### The `"connection"` property

      "connection"               TpConnection*         : Read

The TpConnection to which this contact belongs.

### The `"contact-groups"` property

      "contact-groups"           GStrv                 : Read

a GStrv with names of groups of which a contact is a member.

This is set to `NULL` if `TP_CONTACT_FEATURE_CONTACT_GROUPS` is not prepared on this contact, or if the connection does not implement ContactGroups interface.

Since 0.13.14

### The `"contact-info"` property

      "contact-info"             TpContactInfoList*    : Read

A GList of TpContactInfoField representing the vCard of this contact.

This is set to `NULL` if `TP_CONTACT_FEATURE_CONTACT_INFO` is not set on this contact.

Since 0.11.7

### The `"handle"` property

      "handle"                   guint                 : Read

The contact's handle in the Telepathy D-Bus API, a handle of type `TP_HANDLE_TYPE_CONTACT` representing the string given by "identifier".

This handle is referenced using the Telepathy D-Bus API and remains referenced for as long as the TpContact exists and the "connection" remains valid.

However, getting this property does not cause an additional reference to the handle to be held.

If the "connection" becomes invalid, this property is no longer meaningful and will be set to 0.

Default value: 0

### The `"identifier"` property

      "identifier"               gchar*                : Read

The contact's identifier in the instant messaging protocol (e.g. XMPP JID, SIP URI, AOL screenname or IRC nick - whatever the underlying protocol uses to identify a user).

This is never `NULL` for contact objects that are visible to library-user code.

Default value: NULL

### The `"is-blocked"` property

      "is-blocked"               gboolean              : Read

`TRUE` if the contact has been blocked.

This is set to `FALSE` if `TP_CONTACT_FEATURE_CONTACT_BLOCKING` is not prepared on this contact, or if the connection does not implement ContactBlocking interface.

Default value: FALSE

Since 0.17.0

### The `"location"` property

      "location"                 GHashTable_gchararray+GValue_*  : Read

If this contact has set a user-defined location, a string to GValue * hash table containing his location. If not, `NULL`. `tp_asv_get_string()` and similar functions can be used to access the contents.

This may be `NULL` even if the contact has set a location, if this TpContact object has not been set up to track `TP_CONTACT_FEATURE_LOCATION`.

Since 0.11.1

### The `"location-vardict"` property

      "location-vardict"         GVariant*             : Read

If this contact has set a user-defined location, a string to variant map containing his location. If not, `NULL`. `tp_vardict_get_string()` and similar functions can be used to access the contents.

This may be `NULL` even if the contact has set a location, if this TpContact object has not been set up to track `TP_CONTACT_FEATURE_LOCATION`.

This property contains the same information as "location", in a different format.

Allowed values: GVariant<a{sv}>

Default value: NULL

Since 0.19.10

### The `"presence-message"` property

      "presence-message"         gchar*                : Read

If this contact has set a user-defined status message, that message; if not, an empty string (which user interfaces may replace with a localized form of the "presence-status" or "presence-type").

This may be an empty string even if the contact has set a message, if this TpContact object has not been set up to track `TP_CONTACT_FEATURE_PRESENCE`. It is never `NULL`.

Default value: ""

### The `"presence-status"` property

      "presence-status"          gchar*                : Read

A string representing the presence status of this contact. This may be a well-known string from the Telepathy specification, like "available", or a connection-manager-specific string, like "out-to-lunch".

This may be an empty string if this TpContact object has not been set up to track `TP_CONTACT_FEATURE_PRESENCE`. It is never `NULL`.

Default value: ""

### The `"presence-type"` property

      "presence-type"            guint                 : Read

The TpConnectionPresenceType representing the type of presence status for this contact.

This is provided so even unknown values for "presence-status" can be classified into their fundamental types.

This may be `TP_CONNECTION_PRESENCE_TYPE_UNSET` if this TpContact has not been set up to track `TP_CONTACT_FEATURE_PRESENCE`.

Default value: 0

### The `"publish-request"` property

      "publish-request"          gchar*                : Read

The message that contact sent when they requested permission to see the local user's presence, if "publish-state" is `TP_SUBSCRIPTION_STATE_ASK`, an empty string ("") otherwise.

This is set to `NULL` until `TP_CONTACT_FEATURE_SUBSCRIPTION_STATES` has been prepared, and it is guaranteed to be non-`NULL` afterward.

Default value: NULL

Since 0.13.12

### The `"publish-state"` property

      "publish-state"            guint                 : Read

A TpSubscriptionState indicating the state of this contact's subscription to the local user's presence.

This is set to `TP_SUBSCRIPTION_STATE_UNKNOWN` until `TP_CONTACT_FEATURE_SUBSCRIPTION_STATES` has been prepared

Default value: 0

Since 0.13.12

### The `"subscribe-state"` property

      "subscribe-state"          guint                 : Read

A TpSubscriptionState indicating the state of the local user's subscription to this contact's presence.

This is set to `TP_SUBSCRIPTION_STATE_UNKNOWN` until `TP_CONTACT_FEATURE_SUBSCRIPTION_STATES` has been prepared

Default value: 0

Since 0.13.12
