Class ContainerValueIdGenerator

java.lang.Object

com.evolveum.midpoint.schema.util.cid.ContainerValueIdGenerator

public class ContainerValueIdGenerator
extends Object

Generator assigning missing IDs to PCVs of multi-value containers. Originally internal to "new repo" (sqale), now used also from the lens (clockwork) - when simulating the effect of deltas on the objects during execution of operations in simulation mode.

ContainerValueIdGenerator

public ContainerValueIdGenerator(@NotNull
                                 @NotNull PrismObject<S> object)

Method Detail

generateForNewObject

public long generateForNewObject()
                          throws SchemaException

Method inserts IDs for prism container values without IDs and returns highest CID. This directly changes the object provided as a parameter, if necessary.

Throws:

SchemaException

forModifyObject

public ContainerValueIdGenerator forModifyObject(long containerIdSeq)
                                          throws SchemaException

Initializes the generator for modify object and checks that no previous CIDs are missing. This is a critical step before calling processModification(com.evolveum.midpoint.prism.delta.ItemDelta<?, ?>).

Throws:

SchemaException

processModification

public void processModification(ItemDelta<?,?> modification)
                         throws SchemaException

This checks the modification for containers without assigned CIDs and adds them. This changes values inside the modification and this *must be called before the modification is applied to the prism object*. Theoretically, the changes may affect the prism object after the fact, but if any cloning is involved this may not be true, so preferably use this *before* applying the modification.

Throws:

SchemaException

nextId

public long nextId()

getGenerated

public int getGenerated()

lastUsedId

public long lastUsedId()

isOverwrittenId

public boolean isOverwrittenId(Long id)
