Method Detail

revise

public static <E extends DataObject<E> & UniqueidentifiedInterface<E> & VersionedInterface<E>> E[] revise(E[] objectbatch,
                                                                                                          Versioned<E>[] versionedarrayforbatch)

forceaslatestversion

public void forceaslatestversion(E object)

Forces this object as the latest version. This should be used carefully, and mostly to repair corrupted data. It does not change the order of versions between themselves (result of getPreviousVersion() ).

Parameters:

object - provided object

revise

public E revise(E object)

creates a new version of the object from the current latest version

Parameters:

object - the object to create the new version for

Returns:

the just created version

postprocUniqueidentifiedDelete

public static <E extends DataObject<E> & UniqueidentifiedInterface<E> & VersionedInterface<E>> void postprocUniqueidentifiedDelete(E[] objectbatch,
                                                                                                                                   Versioned<E>[] versionedarrayforbatch)

massively processes an array of deleted objects

Parameters:

objectbatch - the batch of object

versionedarrayforbatch - the corresponding batch of versioned properties

postprocUniqueidentifiedDelete

public void postprocUniqueidentifiedDelete(E object)

processes deleted objects. Mostly, if the object deleted is the latest version, then previous version becomes the latest

Parameters:

object - the object deleted

getpreviousversion

public E getpreviousversion(E object)

gets the previous version of an object

Parameters:

object - the object to start the search on

Returns:

the previous version if present, null else

canberevised

public boolean canberevised(E object)

checks if the object can be revised

Parameters:

object - the object to check

Returns:

true if object can be revised

preprocStoredobjectInsert

public static <E extends DataObject<E> & UniqueidentifiedInterface<E> & VersionedInterface<E>> void preprocStoredobjectInsert(E[] objectbatch,
                                                                                                                              Versioned<E>[] versionedbatch)

pre-treatment of the object before insert

Parameters:

objectbatch - batch of object

versionedbatch - corresponding batch of versioned properties

preprocStoredobjectInsert

public void preprocStoredobjectInsert(E object)

pre-process the object before inserting. Creates the first version of the version scheme, the master id, and of course, version just created for the new object is the latest

Parameters:

object - the object to pre-process

getVersion

public java.lang.String getVersion()

Returns:

the version

getLastversion

public java.lang.String getLastversion()

Returns:

a string indicator if this version if the latest ( values are 'Y' and 'N')

getMasterid

public DataObjectMasterId<E> getMasterid()

Returns:

the id common to all versions of the object (each version will get its own version id)

setDependentPropertyUniqueidentified

public void setDependentPropertyUniqueidentified(Uniqueidentified<E> uniqueidentified)

sets the dependent property unique identified

Parameters:

uniqueidentified - the dependent property
