Interface GroupProvider

All Known Implementing Classes:
AbstractGroupProvider, CrowdGroupProvider, DefaultGroupProvider, GroupMultiProvider, HybridGroupProvider, JDBCGroupProvider, LdapGroupProvider, MappedGroupProvider

public interface GroupProvider
Provider interface for groups. As grouped entities are thought to represent end-user entities, a group can be thought of as a collection of bare (not full) JIDs. The method of the Group class and its associated API will accept both bare and full JIDs, but are expected to 'cast down' a full JID to a bare JID prior to processing it. Developers that wish to integrate with their own group system must implement this class and then register the implementation with Openfire in the openfire.xml file. An entry in that file would look like the following:
   <provider>
     <group>
       <className>com.foo.auth.CustomGroupProvider</className>
     </group>
   </provider>

    • updateMember

      void updateMember(String groupName, org.xmpp.packet.JID user, boolean administrator) throws GroupNotFoundException

      user - the (bare) JID of the entity with new privileges

    • deleteMember

      void deleteMember(String groupName, org.xmpp.packet.JID user)
      Deletes an entity from a group (optional operation). Implementations should use the bare JID representation of the JID passed as an argument to this method.
      Parameters:
      groupName - the group name.
      user - the (bare) JID of the entity to delete.
      Throws:

    • isReadOnly

      boolean isReadOnly()

      Returns:
      true if the user provider is read-only.
    • search

      Collection<String> search(String query)
      Returns the group names that match a search. The search is over group names and implicitly uses wildcard matching (although the exact search semantics are left up to each provider implementation). For example, a search for "HR" should match the groups "HR", "HR Department", and "The HR People".

      Before searching or showing a search UI, use the isSearchSupported() method to ensure that searching is supported.

      Parameters:
      query - the search string for group names.
      Returns:
      all groups that match the search.
    • search

      Collection<String> search(String query, int startIndex, int numResults)
      Returns the group names that match a search given a start index and desired number of results. The search is over group names and implicitly uses wildcard matching (although the exact search semantics are left up to each provider implementation). For example, a search for "HR" should match the groups "HR", "HR Department", and "The HR People".

      Before searching or showing a search UI, use the isSearchSupported() method to ensure that searching is supported.

      Parameters:
      query - the search string for group names.
      startIndex - start index in results.
      numResults - number of results to return.
      Returns:
      all groups that match the search.
    • search

      Collection<String> search(String key, String value)
      Returns the names of groups that have a property matching the given key/value pair. This provides a simple extensible search mechanism for providers with differing property sets and storage models. The semantics of the key/value matching (wildcard support, scoping, etc.) are unspecified by the interface and may vary for each implementation. Before searching or showing a search UI, use the isSearchSupported() method to ensure that searching is supported.
      Parameters:
      key - The name of a group property (e.g. "sharedRoster.showInRoster")
      value - The value to match for the given property
      Returns:
      unmodifiable Collection of group names that match the given key/value pair.
    • isSearchSupported

      boolean isSearchSupported()
      Returns true if group searching is supported by the provider.
      Returns:
      true if searching is supported.
    • loadProperties

      PersistableMap<String,String> loadProperties(Group group)
      Loads the group properties (if any) from the backend data store. If the properties can be changed, the provider implementation must ensure that updates to the resulting Map are persisted to the backend data store. Otherwise, if a mutator method is called, the implementation should throw an UnsupportedOperationException. If there are no corresponding properties for the given group, or if the provider does not support group properties, this method should return an empty Map rather than null.
      Parameters:
      group - The target group
      Returns:
      The properties for the given group
