Description

GDataContactsGroup is a subclass of GDataEntry to represent a group from a Google address book.

For more details of Google Contacts' GData API, see the

online documentation.

The user-set name of the group is stored in the “title” property, retrievable using gdata_entry_get_title(). Note that for system groups (see “system-group-id”), this group name is provided by Google, and is not localised. Clients should provide their own localised group names for the system groups.

In addition to all the standard properties available for a group, GDataContactsGroup supports an additional kind of property: extended properties. Extended properties, set with gdata_contacts_group_set_extended_property() and retrieved with gdata_contacts_group_get_extended_property(), are provided as a method of storing client-specific data which shouldn't be seen or be editable by the user, such as IDs and cache times.

Functions

gdata_contacts_group_new ()

GDataContactsGroup *
gdata_contacts_group_new (const gchar *id);

Creates a new GDataContactsGroup with the given ID and default properties.

Parameters

id

the group's ID, or NULL.

[allow-none]

Returns

a new GDataContactsGroup; unref with g_object_unref()

Since: 0.7.0


gdata_contacts_group_get_edited ()

gint64
gdata_contacts_group_get_edited (GDataContactsGroup *self);

Gets the “edited” property. If the property is unset, -1 will be returned.

Parameters

self

a GDataContactsGroup

 

Returns

the UNIX timestamp for the time the file was last edited, or -1

Since: 0.7.0


gdata_contacts_group_is_deleted ()

gboolean
gdata_contacts_group_is_deleted (GDataContactsGroup *self);

Returns whether the group has recently been deleted. This will always return FALSE unless “show-deleted” has been set to TRUE for the query which returned the group; then this function will return TRUE only if the group has been deleted.

If a group has been deleted, no other information is available about it. This is designed to allow groups to be deleted from local address books using incremental updates from the server (e.g. with “updated-min” and “show-deleted”).

Parameters

self

a GDataContactsGroup

 

Returns

TRUE if the group has been deleted, FALSE otherwise

Since: 0.7.0


gdata_contacts_group_get_system_group_id ()

const gchar *
gdata_contacts_group_get_system_group_id
                               (GDataContactsGroup *self);

Gets the “system-group-id” property. If the group is not a system group, NULL will be returned.

Parameters

self

a GDataContactsGroup

 

Returns

the group's system group ID, or NULL

Since: 0.7.0


gdata_contacts_group_get_extended_property ()

const gchar *
gdata_contacts_group_get_extended_property
                               (GDataContactsGroup *self,
                                const gchar *name);

Gets the value of an extended property of the group. Each group can have up to 10 client-set extended properties to store data of the client's choosing.

Parameters

self

a GDataContactsGroup

 

name

the property name; an arbitrary, unique string

 

Returns

the property's value, or NULL

Since: 0.7.0


gdata_contacts_group_get_extended_properties ()

GHashTable *
gdata_contacts_group_get_extended_properties
                               (GDataContactsGroup *self);

Gets the full list of extended properties of the group; a hash table mapping property name to value.

Parameters

self

a GDataContactsGroup

 

Returns

a GHashTable of extended properties.

[transfer none]

Since: 0.7.0


gdata_contacts_group_set_extended_property ()

gboolean
gdata_contacts_group_set_extended_property
                               (GDataContactsGroup *self,
                                const gchar *name,
                                const gchar *value);

Sets the value of a group's extended property. Extended property names are unique (but of the client's choosing), and reusing the same property name will result in the old value of that property being overwritten.

To unset a property, set value to NULL or an empty string.

A group may have up to 10 extended properties, and each should be reasonably small (i.e. not a photo or ringtone). For more information, see the

online documentation.

FALSE will be returned if you attempt to add more than 10 extended properties.

Parameters

self

a GDataContactsGroup

 

name

the property name; an arbitrary, unique string

 

value

the property value, or NULL.

[allow-none]

Returns

TRUE if the property was updated or deleted successfully, FALSE otherwise

Since: 0.7.0

Property Details

The “deleted” property

  “deleted”                  gboolean

Whether the entry has been deleted.

Flags: Read

Default value: FALSE

Since: 0.7.0


The “edited” property

  “edited”                   gint64

The last time the group was edited. If the group has not been edited yet, the content indicates the time it was created.

For more information, see the Atom Publishing Protocol specification.

Flags: Read

Allowed values: >= -1

Default value: -1

Since: 0.7.0


The “system-group-id” property

  “system-group-id”          gchar *

The system group ID for this group, if it's a system group. If the group is not a system group, this is NULL. Otherwise, it is one of the four system group IDs: GDATA_CONTACTS_GROUP_CONTACTS, GDATA_CONTACTS_GROUP_FRIENDS, GDATA_CONTACTS_GROUP_FAMILY and GDATA_CONTACTS_GROUP_COWORKERS.

If this is non-NULL, the group name stored in “title” will not be localised, so clients should provide localised group names of their own for each of the system groups. Whether a group is a system group should be detected solely on the basis of the value of this property, not by comparing the group name (“title”) or entry ID (“id”). The entry ID is not the same as the system group ID.

Flags: Read

Default value: NULL

Since: 0.7.0
