Method Summary

JackrabbitAccessControlPolicy[]	getApplicablePolicies(Principal principal) Returns the applicable policies for the specified principal or an empty array if no additional policies can be applied.

Method Detail

getApplicablePolicies

JackrabbitAccessControlPolicy[] getApplicablePolicies(Principal principal)
                                                      throws AccessDeniedException,
                                                             AccessControlException,
                                                             UnsupportedRepositoryOperationException,
                                                             RepositoryException

Returns the applicable policies for the specified principal or an empty array if no additional policies can be applied.

Parameters:

principal - A principal known to the editing session.

Returns:

array of policies for the specified principal. Note that the policy object returned must reveal the path of the node where they can be applied later on using AccessControlManager.setPolicy(String, javax.jcr.security.AccessControlPolicy).

Throws:

AccessDeniedException - if the session lacks MODIFY_ACCESS_CONTROL privilege.

AccessControlException - if the specified principal does not exist or if another access control related exception occurs.

UnsupportedRepositoryOperationException - if editing access control policies by principal is not supported.

RepositoryException - if another error occurs.

getPolicies

JackrabbitAccessControlPolicy[] getPolicies(Principal principal)
                                            throws AccessDeniedException,
                                                   AccessControlException,
                                                   UnsupportedRepositoryOperationException,
                                                   RepositoryException

Returns the AccessControlPolicy objects that have been set for the given principal or an empty array if no policy has been set. This method reflects the binding state, including transient policy modifications.

Parameters:

principal - A valid principal.

Returns:

The policies defined for the given principal or an empty array.

Throws:

AccessDeniedException - if the session lacks READ_ACCESS_CONTROL privilege.

AccessControlException - if the specified principal does not exist or if another access control related exception occurs.

UnsupportedRepositoryOperationException - if editing access control policies by principal is not supported.

RepositoryException - If another error occurs.

hasPrivileges

boolean hasPrivileges(String absPath,
                      Set<Principal> principals,
                      Privilege[] privileges)
                      throws PathNotFoundException,
                             AccessDeniedException,
                             RepositoryException

Returns whether the given set of Principals has the specified privileges for absolute path absPath, which must be an existing node.

Testing an aggregate privilege is equivalent to testing each non aggregate privilege among the set returned by calling Privilege.getAggregatePrivileges() for that privilege.

The results reported by the this method reflect the net effect of the currently applied control mechanisms. It does not reflect unsaved access control policies or unsaved access control entries. Changes to access control status caused by these mechanisms only take effect on Session.save() and are only then reflected in the results of the privilege test methods.

Since this method allows to view the privileges of principals other than included in the editing session, this method must throw AccessDeniedException if the session lacks READ_ACCESS_CONTROL privilege for the absPath node.

Parameters:

absPath - an absolute path.

principals - a set of Principals for which is the given privileges are tested.

privileges - an array of Privileges.

Returns:

true if the session has the specified privileges; false otherwise.

Throws:

PathNotFoundException - if no node at absPath exists or the session does not have sufficent access to retrieve a node at that location.

AccessDeniedException - if the session lacks READ_ACCESS_CONTROL privilege for the absPath node.

RepositoryException - if another error occurs.

getPrivileges

Privilege[] getPrivileges(String absPath,
                          Set<Principal> principals)
                          throws PathNotFoundException,
                                 AccessDeniedException,
                                 RepositoryException

Returns the privileges the given set of Principals has for absolute path absPath, which must be an existing node.

The returned privileges are those for which hasPrivileges(java.lang.String, java.util.Set, javax.jcr.security.Privilege[]) would return true.

The results reported by the this method reflect the net effect of the currently applied control mechanisms. It does not reflect unsaved access control policies or unsaved access control entries. Changes to access control status caused by these mechanisms only take effect on Session.save() and are only then reflected in the results of the privilege test methods.

Since this method allows to view the privileges of principals other than included in the editing session, this method must throw AccessDeniedException if the session lacks READ_ACCESS_CONTROL privilege for the absPath node.

Note that this method does not resolve any group membership, as this is the job of the user manager. nor does it augment the set with the "everyone" principal.

Parameters:

absPath - an absolute path.

principals - a set of Principals for which is the privileges are retrieved.

Returns:

an array of Privileges.

Throws:

PathNotFoundException - if no node at absPath exists or the session does not have sufficient access to retrieve a node at that location.

AccessDeniedException - if the session lacks READ_ACCESS_CONTROL privilege for the absPath node.

RepositoryException - if another error occurs.
