Method Detail

create

public void create(KerberosKeytabPrincipalEntity kerberosKeytabPrincipalEntity)

create

public void create(KerberosKeytabEntity kerberosKeytabEntity,
                   HostEntity hostEntity,
                   KerberosPrincipalEntity principalEntity)

                                                                                 HostEntity hostEntity,

Find or create KerberosKeytabPrincipalEntity with specified dependecies.

Parameters:

kerberosKeytabEntity - KerberosKeytabEntity which owns this principal

hostEntity - HostEntity which owns this principal

kerberosPrincipalEntity - KerberosPrincipalEntity which related to this principal

Returns:

evaluated entity

merge

public KerberosKeytabPrincipalEntity merge(KerberosKeytabPrincipalEntity kerberosKeytabPrincipalEntity)

remove

public void remove(KerberosKeytabPrincipalEntity kerberosKeytabPrincipalEntity)

remove

public void remove(Collection<KerberosKeytabPrincipalEntity> kerberosKeytabPrincipalEntities)

findByPrincipal

public List<KerberosKeytabPrincipalEntity> findByPrincipal(String principal)

findByHost

public List<KerberosKeytabPrincipalEntity> findByHost(Long hostId)

findByHostAndKeytab

public List<KerberosKeytabPrincipalEntity> findByHostAndKeytab(Long hostId,
                                                               String keytabPath)

findByHostKeytabAndPrincipal

public KerberosKeytabPrincipalEntity findByHostKeytabAndPrincipal(Long hostId,
                                                                  String keytabPath,
                                                                  String principalName)

findByKeytabAndPrincipalNullHost

public KerberosKeytabPrincipalEntity findByKeytabAndPrincipalNullHost(String keytabPath,
                                                                      String principal)

findByNaturalKey

public KerberosKeytabPrincipalEntity findByNaturalKey(Long hostId,
                                                      String keytabPath,
                                                      String principalName)

Ideally for this record PK must be (hostId, keytabPath, principalName), but in some cases hostId can be null. So surrogate auto-generated PK used, and unique constraint for (hostId, keytabPath, principalName) applied. This method checks if hostId is null and calls specific method.

Parameters:

hostId - host id

keytabPath - keytab path

principalName - principal name

Returns:

keytab found

public boolean exists(Long hostId,
                      String keytabPath,
                      String principalName)

findAll

public List<KerberosKeytabPrincipalEntity> findAll()

remove

public void remove(List<KerberosKeytabPrincipalEntity> entities)

removeByHost

public void removeByHost(Long hostId)
