Description copied from interface: AccessManager

Determines whether the item with the specified itemPath or itemId can be read. Either of the two parameters may be null.
Note, that this method should only be called for persisted items as NEW items may not be visible to the permission evaluation. For new items AccessManager.isGranted(Path, int) should be used instead.

If this method is called with both Path and ItemId it is left to the evaluation, which parameter is used.

Specified by:

canRead in interface AccessManager

Parameters:

itemPath - The path to the item or null if itemId should be used to determine the READ permission.

itemId - Id of the item to be tested or null if the itemPath should be used to determine the permission.

Returns:

true if the item can be read; otherwise false.

Throws:

javax.jcr.RepositoryException - if the item is NEW and only an itemId is specified or if another error occurs.

Specified by:

canAccess in interface AccessManager

Parameters:

Returns:

true if the subject of the current context is granted access to the given workspace; otherwise false.

Throws:

hasPrivileges

public boolean hasPrivileges(String absPath,
                    Set<Principal> principals,
                    javax.jcr.security.Privilege[] privileges)
                      throws javax.jcr.PathNotFoundException,
                             javax.jcr.RepositoryException

Description copied from interface: JackrabbitAccessControlManager

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.

Specified by:

hasPrivileges in interface JackrabbitAccessControlManager

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:

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

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

javax.jcr.RepositoryException - if another error occurs.

                                                    javax.jcr.RepositoryException

Description copied from interface: JackrabbitAccessControlManager

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 JackrabbitAccessControlManager.hasPrivileges(java.lang.String, java.util.Set<java.security.Principal>, 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.

Specified by:

getPrivileges in interface JackrabbitAccessControlManager

Parameters:

absPath - an absolute path.

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

Returns:

an array of Privileges.

Throws:

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

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

javax.jcr.RepositoryException - if another error occurs.
