Class ElementState<O extends ObjectType>

java.lang.Object

com.evolveum.midpoint.model.impl.lens.ElementState<O>

All Implemented Interfaces:

Serializable, Cloneable

public class ElementState<O extends ObjectType>
extends Object
implements Serializable, Cloneable

Encapsulates the maintenance of the state of an element (focus, projection). Holds mainly: - basic information like type, definition, and OID - state: old, current, new - deltas: primary, secondary, current (i.e. current -> new), summary (i.e. old -> new) - archived secondary deltas - flags related to the validity of computed components (see below), to avoid needless recomputation - various other state flags (see in the description) Implementation notes: 1. Computed components (current, summary delta, adjusted current object, new object) are evaluated lazily. Their validity is indicated by appropriate flags, driving their (re)computation. 2. Because of their complexity and interdependence, state-changing operations are grouped in a separate region: State updates.

Method Detail

getOid

public String getOid()

getNewObject

public PrismObject<O> getNewObject()

getCurrentDelta

public ObjectDelta<O> getCurrentDelta()

getSummaryDelta

public ObjectDelta<O> getSummaryDelta()

getArchivedSecondaryDeltas

@NotNull
public @NotNull ObjectDeltaWaves<O> getArchivedSecondaryDeltas()

getRelativeObjectDeltaObject

public ObjectDeltaObject<O> getRelativeObjectDeltaObject()
                                                  throws SchemaException

Throws:

SchemaException

getAbsoluteObjectDeltaObject

public ObjectDeltaObject<O> getAbsoluteObjectDeltaObject()
                                                  throws SchemaException

Throws:

SchemaException

swallowToSecondaryDelta

public void swallowToSecondaryDelta(LensElementContext<?> context,
                                    ItemDelta<?,?> itemDelta)
                             throws SchemaException

Throws:

SchemaException

setCurrentObjectAndOid

public void setCurrentObjectAndOid(@NotNull
                                   @NotNull PrismObject<O> object)

Sets the current object and updates the OID as well. Used when OID may change (on projections). Should be used only by the context loader.

setLoadedObject

public void setLoadedObject(@NotNull
                            @NotNull PrismObject<O> object,
                            boolean add)

Sets both current and (if needed) also the old object. Should be used only by the context loader.

setInitialObject

public void setInitialObject(@NotNull
                             @NotNull PrismObject<O> object,
                             boolean add)

Sets both current and (if applicable) the old object. Almost the same as setLoadedObject(PrismObject, boolean) but the old object is updated regardless of whether it was already set or not.

rememberState

@NotNull
public @NotNull RememberedElementState<O> rememberState()

Creates a representation of a state to be (maybe) restored later. Currently comprises only the secondary deltas. Later we may add also current and summary deltas and new object.

restoreState

public void restoreState(@NotNull
                         @NotNull RememberedElementState<O> rememberedState)

normalize

public void normalize()

clone

public ElementState<O> clone()

Overrides:

clone in class Object

adopt

public void adopt(PrismContext prismContext)
           throws SchemaException

Throws:

SchemaException
