Method Detail

readAclsById

Map readAclsById(ObjectIdentity[] objects,
                 Sid[] sids)

Perform database-specific optimized lookup.

Parameters:

objects - the identities to lookup (required)

sids - the SIDs for which identities are required (may be null - implementations may elect not to provide SID optimisations)

Returns:

a Map where keys represent the ObjectIdentity of the located Acl and values are the located Acl (never null although some entries may be missing; this method should not throw NotFoundException, as a chain of LookupStrategys may be used to automatically create entries if required)
