Class ChildDeltaCreator

java.lang.Object

org.faktorips.runtime.internal.delta.ChildDeltaCreator

public class ChildDeltaCreator
extends Object

Internal utility class to create ModelObjectDelta for associations.

Note that this is an internal utility class whose API may not be stable and thus should not be called by client code directly.

ChildDeltaCreator

@Deprecated
public ChildDeltaCreator(String association,
                                     IDeltaComputationOptions options)

Deprecated. since 19.12. Use ChildDeltaCreator(String, AssociationKind, IDeltaComputationOptions) instead.

Instantiates the creator for the given association name, kind and IDeltaComputationOptions.

Parameters:

association - The name of the association, will be provided to the created delta

options - The IDeltaComputationOptions that configures some behavior of delta computation

ChildDeltaCreator

public ChildDeltaCreator(String association,
                         AssociationKind kind,
                         IDeltaComputationOptions options)

Instantiates the creator for the given association name, kind and IDeltaComputationOptions.

Parameters:

association - The name of the association, will be provided to the created delta

kind - The kind of the association, needed to decide whether to follow an association recursively or not

options - The IDeltaComputationOptions that configures some behavior of delta computation

Method Detail

createChildDeltas

public void createChildDeltas(ModelObjectDelta delta,
                              IModelObject original,
                              IModelObject refObject)

Create and add a child delta for the comparison of original and reference model object.

The objects are compared according to the IDeltaComputationOptions. If one of the objects no longer exists, null is given to the appropriate parameter.

Parameters:

delta - The delta to which the child deltas are added

original - The associated object of the original model object or null if there is no object references

refObject - The associated object of the reference model object or null if there is no object references

createChildDeltas

public void createChildDeltas(ModelObjectDelta delta,
                              List<? extends IModelObject> originals,
                              List<? extends IModelObject> refObjects)

Create and add all child deltas for the list of associated objects. The objects are compared according to the IDeltaComputationOptions.

Parameters:

delta - The delta to which the child deltas are added

originals - The list of associated objects of the original model object

refObjects - The list of associated objects of the reference model object
