                            throws SQLException

Description copied from interface: DSpaceObjectService

Return the dspace object where an ADMIN action right is sufficient to grant the initial authorize check.

Default behaviour is ADMIN right on the object grant right on all other action on the object itself. Subclass should override this method as needed.

Specified by:

getAdminObject in interface DSpaceObjectService<Bundle>

Overrides:

getAdminObject in class DSpaceObjectServiceImpl<Bundle>

Parameters:

context - DSpace context

bundle - DSpaceObject

action - ID of action being attempted, from org.dspace.core.Constants. The ADMIN action is not a valid parameter for this method, an IllegalArgumentException should be thrown

Returns:

the dspace object, if any, where an ADMIN action is sufficient to grant the original action

Throws:

SQLException - if database error

public DSpaceObject getParentObject(Context context,

Description copied from interface: DSpaceObjectService

Return the dspace object that "own" the current object in the hierarchy. Note that this method has a meaning slightly different from the getAdminObject because it is independent of the action but it is in a way related to it. It defines the "first" dspace object OTHER then the current one, where allowed ADMIN actions imply allowed ADMIN actions on the object self.

Specified by:

getParentObject in interface DSpaceObjectService<Bundle>

Overrides:

getParentObject in class DSpaceObjectServiceImpl<Bundle>

Parameters:

context - DSpace context

bundle - DSpaceObject

Returns:

the dspace object that "own" the current object in the hierarchy
