module Tilia::CardDav::Backend::BackendInterface

CardDAV Backend Interface

Any CardDAV backend must implement this interface.

Note that there are references to 'addressBookId' scattered throughout the class. The value of the addressBookId is completely up to you, it can be any arbitrary value you can use as an unique identifier.

Public Instance Methods

address_books_for_user(principal_uri) click to toggle source

Returns the list of addressbooks for a specific user.

Every addressbook should have the following properties:

id - an arbitrary unique id
uri - the 'basename' part of the url
principaluri - Same as the passed parameter

Any additional clark-notation property may be passed besides this. Some common ones are :

{DAV:}displayname
{urn:ietf:params:xml:ns:carddav}addressbook-description
{http://calendarserver.org/ns/}getctag

@param string principal_uri @return array

# File lib/tilia/card_dav/backend/backend_interface.rb, line 31
def address_books_for_user(principal_uri)
end
card(address_book_id, card_uri) click to toggle source

Returns a specfic card.

The same set of properties must be returned as with getCards. The only exception is that 'carddata' is absolutely required.

If the card does not exist, you must return false.

@param mixed address_book_id @param string card_uri @return array

# File lib/tilia/card_dav/backend/backend_interface.rb, line 97
def card(address_book_id, card_uri)
end
cards(addressbook_id) click to toggle source

Returns all cards for a specific addressbook id.

This method should return the following properties for each card:

* carddata - raw vcard data
* uri - Some unique url
* lastmodified - A unix timestamp

It's recommended to also return the following properties:

* etag - A unique etag. This must change every time the card changes.
* size - The size of the card in bytes.

If these last two properties are provided, less time will be spent calculating them. If they are specified, you can also ommit carddata. This may speed up certain requests, especially with large cards.

@param mixed addressbook_id @return array

# File lib/tilia/card_dav/backend/backend_interface.rb, line 84
def cards(addressbook_id)
end
create_address_book(principal_uri, url, properties) click to toggle source

Creates a new address book

@param string principal_uri @param string url Just the 'basename' of the url. @param array properties @return void

# File lib/tilia/card_dav/backend/backend_interface.rb, line 57
def create_address_book(principal_uri, url, properties)
end
create_card(address_book_id, card_uri, card_data) click to toggle source

Creates a new card.

The addressbook id will be passed as the first argument. This is the same id as it is returned from the getAddressBooksForUser method.

The cardUri is a base uri, and doesn't include the full path. The cardData argument is the vcard body, and is passed as a string.

It is possible to return an ETag from this method. This ETag is for the newly created resource, and must be enclosed with double quotes (that is, the string itself must contain the double quotes).

You should only return the ETag if you store the carddata as-is. If a subsequent GET request on the same card does not have the same body, byte-by-byte and you did return an ETag here, clients tend to get confused.

If you don't return an ETag, you can just return null.

@param mixed address_book_id @param string card_uri @param string card_data @return string|null

# File lib/tilia/card_dav/backend/backend_interface.rb, line 136
def create_card(address_book_id, card_uri, card_data)
end
delete_address_book(address_book_id) click to toggle source

Deletes an entire addressbook and all its contents

@param mixed address_book_id @return void

# File lib/tilia/card_dav/backend/backend_interface.rb, line 64
def delete_address_book(address_book_id)
end
delete_card(address_book_id, card_uri) click to toggle source

Deletes a card

@param mixed address_book_id @param string card_uri @return bool

# File lib/tilia/card_dav/backend/backend_interface.rb, line 170
def delete_card(address_book_id, card_uri)
end
multiple_cards(address_book_id, uris) click to toggle source

Returns a list of cards.

This method should work identical to getCard, but instead return all the cards in the list as an array.

If the backend supports this, it may allow for some speed-ups.

@param mixed address_book_id @param array uris @return array

# File lib/tilia/card_dav/backend/backend_interface.rb, line 110
def multiple_cards(address_book_id, uris)
end
update_address_book(address_book_id, prop_patch) click to toggle source

Updates properties for an address book.

The list of mutations is stored in a SabreDAVPropPatch object. To do the actual updates, you must tell this object which properties you're going to process with the handle method.

Calling the handle method is like telling the PropPatch object “I promise I can handle updating this property”.

Read the PropPatch documenation for more info and examples.

@param string address_book_id @param SabreDAVPropPatch prop_patch @return void

# File lib/tilia/card_dav/backend/backend_interface.rb, line 48
def update_address_book(address_book_id, prop_patch)
end
update_card(address_book_id, card_uri, card_data) click to toggle source

Updates a card.

The addressbook id will be passed as the first argument. This is the same id as it is returned from the getAddressBooksForUser method.

The cardUri is a base uri, and doesn't include the full path. The cardData argument is the vcard body, and is passed as a string.

It is possible to return an ETag from this method. This ETag should match that of the updated resource, and must be enclosed with double quotes (that is: the string itself must contain the actual quotes).

You should only return the ETag if you store the carddata as-is. If a subsequent GET request on the same card does not have the same body, byte-by-byte and you did return an ETag here, clients tend to get confused.

If you don't return an ETag, you can just return null.

@param mixed address_book_id @param string card_uri @param string card_data @return string|null
