Interface IGroupMembershipProvider

  • All Known Implementing Classes:
    AbstractGroupMembershipProvider, DatabaseViewGroupMembershipProvider, StandardGroupMembershipProvider
    @StableMinor(version="14.0",
             sinceVersion="4.2")
public interface IGroupMembershipProvider
    Provides group membership information. A portal solution may configure a group type to use a specific implementation of this interface as a way to customize group membership definition/calculation.

    Membership caching is responsibility of IGroupMembershipProvider. It decides its own caching policy, using one appropriated to its membership calculation logic.

    All methods of this interface are called within a transactional context and within a user session context.

      • getGroupTypeConfigurationInterfaceId

        String getGroupTypeConfigurationInterfaceId()
        Returns the interface identifier for editing configurations at a group type scope.

        The interface will receive the parameter groupTypeId with the identifier of the group type being configured.

        Usually deleteGroupTypeMembershipData() will be used to delete data stored using this configuration interface.

        Returns:
        the interface identifier, or null if no such configuration interface exists.
        Since:
        4.2.1

      • getGroupConfigurationInterfaceId

        String getGroupConfigurationInterfaceId()
        Returns the interface identifier for editing configurations at a group scope.

        The interface will receive the parameter groupId with the identifier of the group being configured.

        Usually deleteGroupMembershipData(String) will be used to delete data stored using this configuration interface.

        Returns:
        the interface identifier, or null if no such configuration interface exists.

        4.2.1

      • addMember

        void addMember​(String groupId,
               String memberId)
        throws PortalException
        Add a member into a group.
        Parameters:
        groupId - the group identifier.
        memberId - the member identifier.
        Throws:
        UnsupportedOperationException - if this membership provider is read-only and does not supports adding members through this interface.
        PortalException
        Since:
        4.2.1

      • removeMember

        void removeMember​(String groupId,

           throws PortalException
        Remove a member from a group.
        Parameters:
        groupId - the group identifier.
        memberId - the member identifier.
        Throws:
        UnsupportedOperationException - if this membership provider is read-only and does not supports removing members through this interface. Note that if the member ceases to exists, and, even if this method throws this exception, getMembers(String, int) should no longer return that member as it does not exist.
        PortalException
        Since:

      • getGroups

        Collection<String> getGroups​(String principalId)
                      throws PortalException
        Returns the groups of a principal. Only the direct groups, belonging to the group type this provider is serving, are to be returned.
        Parameters:
        principalId - the principal identifier.
        Returns:
        the groups identifiers.
        Throws:

      • deleteGroupTypeMembershipData

        void deleteGroupTypeMembershipData()
                            throws PortalException
        Deletes all data stored for managing the membership of a group type. This method is called before a group type is deleted, in the same transaction in which the deletion will be performed.

        This allows this provider to cleanup membership, configuration or other data that it stores for managing a group type membership.

        Throws:
        PortalException
        Since:
        4.2.1

      • deleteGroupMembershipData

        void deleteGroupMembershipData​(String groupId)
                        throws PortalException
        Deletes all data stored for managing the membership of a group. This method is called before a group is deleted, in the same transaction in which the deletion will be performed.

        This allows this provider to cleanup membership, configuration or other data that it stores for managing a group membership.

        This deletion process order is illustrated in the following diagram: IGroupMembershipProvider.deleteGroupConfiguration Sequence Diagram

        Parameters:
        groupId - the group identifier.
        Throws:
        PortalException
