Specified by:

init in interface AccessControlProvider

Overrides:

init in class AbstractAccessControlProvider

Parameters:

systemSession - System session.

configuration - Configuration used to initialize this provider.

Throws:

RepositoryException - If the specified session is not a SessionImpl or if retrieving the observation manager fails.

close

public void close()

Description copied from interface: AccessControlProvider

Closes this provider when it is no longer used by the respective workspace and release resources bound by this provider.

Specified by:

close in interface AccessControlProvider

Overrides:

close in class AbstractAccessControlProvider

getEffectivePolicies

public AccessControlPolicy[] getEffectivePolicies(Path absPath,
                                                  CompiledPermissions permissions)
                                           throws ItemNotFoundException,
                                                  RepositoryException

Description copied from interface: AccessControlProvider

Returns the effective policies for the node at the given absPath.

Specified by:

getEffectivePolicies in interface AccessControlProvider

Parameters:

absPath - an absolute path.

permissions - The effective permissions of the editing sessions that attempts to view the effective policies.

Returns:

The effective policies that apply at absPath or an empty array if the implementation cannot determine the effective policy at the given path.

Throws:

ItemNotFoundException - If no Node with the specified absPath exists.

RepositoryException - If another error occurs.

                                           throws RepositoryException

Description copied from interface: AccessControlProvider

Returns the effective policies for the given principals.

Specified by:

getEffectivePolicies in interface AccessControlProvider

Parameters:

principals - A set of principal.

permissions - The effective permissions of the editing sessions that attempts to view the effective policies. @return The effective policies that are in effect for the given principal or an empty array.

Parameters:

editingSession - The editing session.

Returns:

the ACL editor or null.

                                       throws RepositoryException

Description copied from interface: AccessControlProvider

Compiles the effective policy for the specified set of Principals.

Specified by:

compilePermissions in interface AccessControlProvider
