module Tilia::DavAcl::PrincipalBackend::BackendInterface

Implement this interface to create your own principal backends.

Creating backends for principals is entirely optional. You can also implement Tilia::DavAcl::IPrincipal directly. This interface is used solely by Tilia::DavAcl::AbstractPrincipalCollection.

Public Instance Methods

find_by_uri(uri, principal_prefix) click to toggle source

Finds a principal by its URI.

This method may receive any type of uri, but mailto: addresses will be the most common.

Implementation of this API is optional. It is currently used by the CalDAV system to find principals based on their email addresses. If this API is not implemented, some features may not work correctly.

This method must return a relative principal path, or null, if the principal was not found or you refuse to find it.

@param string uri @param string principal_prefix @return string

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 98
def find_by_uri(uri, principal_prefix)
end
group_member_set(principal) click to toggle source

Returns the list of members for a group-principal

@param string principal @return array

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 105
def group_member_set(principal)
end
group_membership(principal) click to toggle source

Returns the list of groups a principal is a member of

@param string principal @return array

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 112
def group_membership(principal)
end
principal_by_path(path) click to toggle source

Returns a specific principal, specified by it's path. The returned structure should be the exact same as from getPrincipalsByPrefix.

@param string path @return array

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 33
def principal_by_path(path)
end
principals_by_prefix(prefix_path) click to toggle source

Returns a list of principals based on a prefix.

This prefix will often contain something like 'principals'. You are only expected to return principals that are in this base path.

You are expected to return at least a 'uri' for every user, you can return any additional properties if you wish so. Common properties are:

{DAV:}displayname
{http://sabredav.org/ns}email-address - This is a custom SabreDAV
  field that's actually injected in a number of other properties. If
  you have an email address, use this property.

@param string prefix_path @return array

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 24
def principals_by_prefix(prefix_path)
end
search_principals(prefix_path, search_properties, test = 'allof') click to toggle source

This method is used to search for principals matching a set of properties.

This search is specifically used by RFC3744's principal-property-search REPORT.

The actual search should be a unicode-non-case-sensitive search. The keys in searchProperties are the WebDAV property names, while the values are the property values to search on.

By default, if multiple properties are submitted to this method, the various properties should be combined with 'AND'. If test is set to 'anyof', it should be combined using 'OR'.

This method should simply return an array with full principal uri's.

If somebody attempted to search on a property the backend does not support, you should simply return 0 results.

You can also just return 0 results if you choose to not support searching at all, but keep in mind that this may stop certain features from working.

@param string prefix_path @param array search_properties @param string test @return array

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 80
def search_principals(prefix_path, search_properties, test = 'allof')
end
update_group_member_set(principal, members) click to toggle source

Updates the list of group members for a group principal.

The principals should be passed as a list of uri's.

@param string principal @param array members @return void

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 122
def update_group_member_set(principal, members)
end
update_principal(path, prop_patch) click to toggle source

Updates one ore more webdav properties on a principal.

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 path @param SabreDAVPropPatch prop_patch @return void

# File lib/tilia/dav_acl/principal_backend/backend_interface.rb, line 50
def update_principal(path, prop_patch)
