ACL Hierarchy Interface

Definition of an Access Control List Hierarchy

This interface defines an Access Control List Hierarchy. With this, it is possible to check if a principal has a specific permission for an object or his parents.

Method Summary

void	checkPermission(String[] objectIds, IPrincipal principal, String permission) This method checks if a principal can perform a permission on the specified object ID array.
boolean	isAllowed(String[] objectIds, IPrincipal principal, String permission) This method checks, if a principal can perform a permission on the specified object ID array.
void	propagade(IPrincipal caller, String rootObjectID, String[] childrenObjectIds) This method propagades the ACEs from the root of the subtree to his nodes and leaves.

Method Detail

isAllowed

boolean isAllowed(String[] objectIds,
                  IPrincipal principal,
                  String permission)
                  throws UMException

This method checks, if a principal can perform a permission on the specified object ID array.

Parameters:

objectIds - This object ID array represent the parent object IDs (the way from the specified object ID to the parent nodes up to the roof).

principal - the principal which has to be checked.

permission - the permission which has to be checked.

Returns:

true if the principal is authorised for the specified permission false otherwise

Throws:

UMException - if the data cannot be read.

propagade

void propagade(IPrincipal caller,
               String rootObjectID,
               String[] childrenObjectIds)
               throws UMException

This method propagades the ACEs from the root of the subtree to his nodes and leaves. These ACEs are inherited.

Parameters:

caller - a principal who has to be the owner of the root ACL

rootObjectID - a String which represents the root of the subtree. His ACEs will be propagated.

childrenObjectIds - a String array which represents all child object IDs under the root of the subtree.

Throws:

UMException - if the data cannot be set.

checkPermission

void checkPermission(String[] objectIds,
                     IPrincipal principal,
                     String permission)
                     throws UMException

This method checks if a principal can perform a permission on the specified object ID array.

Parameters:

objectIds - This object ID array represent the parent object IDs (the way from the specified object ID to the parent nodes up to the roof)

principal - the principal which has to be checked

permission - the permission which has to be checked

Throws:

UMException - if the principal has not the specified permission
