Method Detail

findAcls

Map<AclObjectIdentity,Set<AclEntry>> findAcls(List<AclObjectIdentity> objectIdsToLookup)

Loads the AclEntry instances that apply for the passed AclObjectIdentity objects. The returned map is keyed on the passed objects, with the values being sets of the applicable AclEntry instances, sorted by the order parameter. Any unknown objects will not have a map key.

Parameters:

objectIdsToLookup - the objects to find AclEntry information for.

Returns:

a map with a set of AclEntry instances for each AclObjectIdentity passed as an argument.

findAclObjectIdentity

AclObjectIdentity findAclObjectIdentity(AclObjectIdentity objectId)

Loads a fully populated AclObjectIdentity object from the database for the provided AclObjectIdentity. The provided object must contain 'id' and 'objectClass' information.

Parameters:

objectId - the AclObjectIdentity to load from the database.

Returns:

a fully populated AclObjectIdentity object.

findAclObjectIdentityChildren

List<AclObjectIdentity> findAclObjectIdentityChildren(AclObjectIdentity objectId)

Loads the AclObjectIdentity instances that use the specified parent.

Parameters:

objectId - the object to find children for.

Returns:

the list of children.

deleteAcls

void deleteAcls(List<AclObjectIdentity> objectIdsToDelete)

Removes all relevant records for the provided AclObjectIdentity instances.

Parameters:

objectIdsToDelete - the AclObjectIdentity instances representing the records to delete.

saveAcl

void saveAcl(AclObjectIdentity aoi)
      throws AclAlreadyExistsException

Saves an AclObjectIdentity record in the database. It will have no entries.

Parameters:

aoi - the AclObjectIdentity to save.

Throws:

AclAlreadyExistsException - if the passed object identity already has a record.

updateAcl

void updateAcl(AclObjectIdentity aoi,
               List<AclEntry> entries)
        throws AclNotFoundException

Changes an existing AclObjectIdentity or the related AclEntry records in the database.

Parameters:

aoi - the AclObjectIdentity to update.

entries - the list of AclEntry objects to update.

Throws:

AclNotFoundException - if the relevant record could not be found.
