Overrides:

getRhsValue in class JboCompareValidator

setRhsValue

public void setRhsValue(java.lang.Object rhsValue)

Description copied from class: JboCompareValidator

public void setCompareValue(java.lang.String compareValue)

Overrides:

validateValueWithContext

public boolean validateValueWithContext(JboValidatorContext evObj,
                                        java.lang.Object value)

Description copied from class: JboAbstractValidator

Called internally by the framework with validation OnCondition is true or there is no validation OnCondition. This method should not be directly invoked in applications.

Overrides:

validateValueWithContext in class JboCompareValidator

resolve

public void resolve(ValidationManager owner,
                    StructureDef structDef,
                    PersistableDefObject defObj)

Specified by:

resolve in interface JboValidatorHints

Overrides:

resolve in class JboAbstractValidator

loadXMLContents

public void loadXMLContents(DefElement elem)

Overrides:

loadXMLContents in class JboCompareValidator

writeChildren

public void writeChildren(DefWriter jos)

Description copied from interface: PersistentDefinition

Writes the Object's children to the Persistent storage

Specified by:

writeChildren in interface PersistentDefinition

Overrides:

writeChildren in class AbstractValidator

Parameters:

jos - the Output storage for persistence

diffChildren

public DifferDetails diffChildren(DiffMergeable docDef,
                                  DiffMergeable orgDef,
                                  DifferDetails difDetails)

Description copied from interface: DiffMergeable

Performs diff of children defs. This def should enumerate through all its children and diff them and accumulate details of diff into difDetails and return it at the end.

For example, if this def has Child1 and Child2, its implementation should look something like:

    public DifferDetails diffChildren(DiffMergeable docDef, DiffMergeable orgDef, DifferDetails difDetails)
    {
       difDetails = diffChildrenChild1(docDef, orgDef, difDetails);
       difDetails = diffChildrenChild1(docDef, orgDef, difDetails);

       return difDetails;
    }
 

where diffChildrenChild1() uses DifferChildren's helper method diffChildrenList to diff the child defs.

Specified by:

diffChildren in interface DiffMergeable

Overrides:

diffChildren in class AbstractValidator

Parameters:

docDef - the document-level definition

orgDef - the original definition. It could be null if the definition did not exist originally

difDetails - the DifferDetails that accumulate the details of diff from the document-level (top-level) def

Returns:

the DifferDetails that has all the details of diff

applyDiffChildren

public void applyDiffChildren(DifferDetails dif,
                              DiffResolver resolver)

Description copied from interface: DiffMergeable

Applies changes to children defs. dif contains the changes to be applied to the children. For each child def, this method should first retrieve the diff details for the child, which is of type DifferChildren. Then, it should call DifferChildren.applyDiffChanges(oracle.jbo.mom.DiffChildrenMerge, oracle.jbo.mom.DiffResolver) to perform the change operation.

applyChanges() requires a DiffChildrenMerge object, which has the insert, update, and remove methods. 'this' def object must provide implmementation of these operations.

Here is a sample:

    public void applyDiffChildren(DifferDetails dif, DiffResolver resolver)
    {
       DifferChangeMap detailMap = dif.getDetailMap();

       if (detailMap != null)
       {
          DifferChildren difChild1 = (DifferChildren) detailMap.getValue();

          if (difVCs != null)
          {
             DiffChildrenMerge dm = new DiffChildrenMerge()
             {
                public void insertChild(Object id, Object value)
                {
                   .. perform insert op for Child1 ..
                }

                public void updateChild(Object id, Object value, Object oldValue)
                {
                   .. perform update op for Child1 ..
                }

                public void removeChild(Object id)
                {
                   .. perform remove op for Child1 ..
                }
             };

             difChild1.applyDiffChanges(dm, resolver);
          }

          // Similarly for Child2
       }
    }
