Method Detail

getPolicies

public AccessControlPolicy[] getPolicies(String nodePath)
                                  throws AccessControlException,
                                         PathNotFoundException,
                                         RepositoryException

Description copied from interface: AccessControlEditor

Retrieves the policies for the Node identified by the given nodePath. In contrast to AccessControlEditor.editAccessControlPolicies(java.lang.String) this method returns an empty array if no policy has been applied before by calling AccessControlEditor.setPolicy(java.lang.String, javax.jcr.security.AccessControlPolicy)). Still the returned policies are detached from the AccessControlProvider and are only an external representation. Modification will therefore not take effect, until they are written back to the editor and persisted.

Compared to the policy returned by AccessControlProvider.getEffectivePolicies(org.apache.jackrabbit.spi.Path, CompiledPermissions), the scope of the policies it limited to the Node itself and does not take inherited elements into account.

Specified by:

getPolicies in interface AccessControlEditor

Parameters:

nodePath - Absolute path to an existing node object.

Returns:

the policies applied so far or an empty array if no policy has been applied to the node before.

Throws:

AccessControlException - If the Node identified by the given nodePath does not allow access control modifications (e.g. the node itself stores the access control information for its parent).

PathNotFoundException - if no node exists for the given nodePath.

RepositoryException - if an error occurs

getPolicies

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

Always returns an empty array as no applicable policies are exposed.

Specified by:

getPolicies in interface AccessControlEditor

Parameters:

principal - Principal for which the editable policies should be returned.

Returns:

the policies applied so far or an empty array if no policy has been applied before.

Throws:

AccessControlException - if the specified principal does not exist, if this implementation cannot provide policies for individual principals or if same other access control related exception occurs.

RepositoryException - if an error occurs

editAccessControlPolicies

public AccessControlPolicy[] editAccessControlPolicies(String nodePath)
                                                throws AccessControlException,
                                                       PathNotFoundException,
                                                       RepositoryException

Description copied from interface: AccessControlEditor

Retrieves the editable policies for the Node identified by the given nodePath that are applicable but have not yet have been set.
The AccessControlPolicy objects returned are detached from the underlying AccessControlProvider and is only an external representation. Modification will therefore not take effect, until a modified policy is written back to the editor and persisted.

See AccessControlEditor.getPolicies(String) for the corresponding method that returns the editable policies that have been set to the node at nodePath before.

Compared to the policies returned by AccessControlProvider.getEffectivePolicies(org.apache.jackrabbit.spi.Path, CompiledPermissions), the scope of the policies returned by this methods it limited to the Node itself and does never not take inherited elements into account.

Specified by:

editAccessControlPolicies in interface AccessControlEditor

Parameters:

nodePath - Absolute path to an existing node object.

Returns:

an array of editable access control policies.

Throws:

AccessControlException - If the Node identified by the given nodePath does not allow access control modifications.

PathNotFoundException - if no node exists for the given nodePath.

RepositoryException - if an error occurs

Description copied from interface: AccessControlEditor

Returns an array of editable policies for the given principal.

Specified by:

editAccessControlPolicies in interface AccessControlEditor

Parameters:

principal - Principal for which the editable policies should be returned.

Returns:

an array of editable policies for the given principal.

Throws:

AccessDeniedException - If the editing session is not allowed to edit policies.

AccessControlException - if the specified principal does not exist, if this implementation cannot provide policies for individual principals or if same other access control related exception occurs.

RepositoryException - if another error occurs.

Stores the policy template to the respective node.

Specified by:

setPolicy in interface AccessControlEditor

Parameters:

nodePath - Absolute path to an existing node object.

policy - the AccessControlPolicy to store.

Throws:

AccessControlException - If the policy is null or if it is not applicable to the Node identified by the given nodePath.

Specified by:

removePolicy in interface AccessControlEditor

Parameters:
