Class GroupManager

java.lang.Object
org.opends.server.api.plugin.DirectoryServerPlugin<PluginCfg>
org.opends.server.api.plugin.InternalDirectoryServerPlugin
org.opends.server.core.GroupManager
All Implemented Interfaces:
LocalBackendInitializationListener
public final class GroupManager extends InternalDirectoryServerPlugin implements LocalBackendInitializationListener
This class provides a mechanism for interacting with all groups defined in the Directory Server. It will handle all necessary processing at server startup to identify and load all group implementations, as well as to find all group instances within the server.

FIXME: At the present time, it assumes that all of the necessary information about all of the groups defined in the server can be held in memory. If it is determined that this approach is not workable in all cases, then we will need an alternate strategy.

  • Method Details

    • getAllGroups

      public Iterable<Group> getAllGroups()
      Retrieves an Iterable object that may be used to cursor across the group instances defined in the server.
      Returns:
      An Iterable object that may be used to cursor across the group instances defined in the server.

    • getGroup

      public Group getGroup(Dn entryDN)
      Retrieves the group defined in the entry with the specified DN.
      Parameters:
      entryDN - The DN of the entry containing the definition of the group to retrieve.
      Returns:
      The group defined in the entry with the specified DN, or null if no such group is currently defined.

    • doStartup

      public void doStartup()
      Description copied from class: DirectoryServerPlugin
      Performs any processing that should be done when the Directory Server is in the process of starting. This method will be called after virtually all other initialization has been performed but before the connection handlers are started.
      Overrides:
      doStartup in class DirectoryServerPlugin<PluginCfg>

    • performBackendPreInitializationProcessing

      public void performBackendPreInitializationProcessing(LocalBackend<?> backend)
      Performs any processing that may be required whenever a backend is initialized for use in the Directory Server. This method will be invoked after the backend has been initialized but before it has been put into service.

      In this case, the server will search the backend to find all group instances that it may contain and register them with this group manager.

      Specified by:
      performBackendPreInitializationProcessing in interface LocalBackendInitializationListener
      Parameters:
      backend - The backend that has been initialized and is about to be put into service.

    • performBackendPostFinalizationProcessing

      public void performBackendPostFinalizationProcessing(String backendId, Predicate<Dn> handlesEntry)
      Performs any processing that may be required whenever a backend is finalized. This method will be invoked after the backend has been taken out of service and after it has been finalized.

      In this case, the server will de-register all group instances associated with entries in the provided backend.

      Specified by:
      performBackendPostFinalizationProcessing in interface LocalBackendInitializationListener
      Parameters:
      backendId - The backend ID of the backend that has been taken out of service.
      handlesEntry - A predicate which can be used for determining whether the finalized backend contained an entry.

    • doPostCommit

      public void doPostCommit(PostCommitAddOperation addOperation)
      Description copied from class: DirectoryServerPlugin
      Performs any necessary processing that should be done after the Directory Server has committed an add operation.
      Overrides:
      doPostCommit in class DirectoryServerPlugin<PluginCfg>
      Parameters:
      addOperation - The add operation that has just been committed.

    • doPostCommit

      public void doPostCommit(PostCommitDeleteOperation deleteOperation)
      Description copied from class: DirectoryServerPlugin
      Performs any necessary processing that should be done after the Directory Server has committed a delete operation.
      Overrides:
      doPostCommit in class DirectoryServerPlugin<PluginCfg>
      Parameters:
      deleteOperation - The delete operation that has just been committed.

    • doPostCommit

      public void doPostCommit(PostCommitModifyOperation modifyOperation)
      Description copied from class: DirectoryServerPlugin
      Performs any necessary processing that should be done after the Directory Server has committed a modify operation.
      Overrides:
      doPostCommit in class DirectoryServerPlugin<PluginCfg>
      Parameters:
      modifyOperation - The modify operation that has just been committed.

    • doPostCommit

      public void doPostCommit(PostCommitModifyDNOperation modifyDNOperation)
      Description copied from class: DirectoryServerPlugin
      Performs any necessary processing that should be done after the Directory Server has committed a modify DN operation.
      Overrides:
      doPostCommit in class DirectoryServerPlugin<PluginCfg>
      Parameters:
      modifyDNOperation - The modify DN operation that has just been committed.

    • deregisterAllGroups

      public void deregisterAllGroups()
      Removes all group instances that might happen to be registered with the group manager. This method is only intended for testing purposes and should not be called by any other code.
