Class EntryCollector

java.lang.Object
  org.apache.jackrabbit.core.security.authorization.AccessControlObserver
      org.apache.jackrabbit.core.security.authorization.acl.EntryCollector

All Implemented Interfaces:

EventListener, SynchronousEventListener, AccessControlConstants

public class EntryCollector
extends AccessControlObserver
implements AccessControlConstants

EntryCollector collects ACEs defined and effective for a given Node and listens to access control modifications in order to inform listeners.

Field Summary

protected NodeId	rootID The root id.
protected SessionImpl	systemSession The system session used to register an event listener and process the events as well as collect AC entries.

Constructor Detail

EntryCollector

protected EntryCollector(SessionImpl systemSession,
                         NodeId rootID)
                  throws RepositoryException

Parameters:

systemSession -

rootID -

Throws:

RepositoryException

Method Detail

close

protected void close()

Release all resources contained by this instance. It will no longer be used. This implementation only stops listening to ac modification events.

Overrides:

close in class AccessControlObserver

collectEntries

protected List<AccessControlEntry> collectEntries(NodeImpl node,
                                                  EntryFilter filter)
                                           throws RepositoryException

Collect the ACEs effective at the given node applying the specified filter.

Parameters:

node -

filter -

Returns:

Throws:

RepositoryException

getEntries

protected List<AccessControlEntry> getEntries(NodeImpl node)
                                       throws RepositoryException

Retrieve the access control entries defined for the given node. If the node is not access controlled or if the ACL is empty this method returns an empty list.

Parameters:

node -

Returns:

Throws:

RepositoryException

getEntries

protected List<AccessControlEntry> getEntries(NodeId nodeId)
                                       throws RepositoryException

Parameters:

nodeId -

Returns:

Throws:

RepositoryException

getParentId

protected NodeId getParentId(NodeId nodeId)
                      throws RepositoryException

Returns the parentId of the given nodeId.

Parameters:

nodeId -

Returns:

Throws:

RepositoryException

onEvent

public void onEvent(EventIterator events)

Collect is of access controlled nodes that are effected by access control modification together with the corresponding modification type and finally inform listeners about the modifications.

Specified by:

onEvent in interface EventListener

Parameters:

events -
