Method Detail

hasVariables

public boolean hasVariables()

Description copied from interface: VariableManagerOwnerBase

Returns a flag indicating whether this object has Variables or not.

Specified by:

hasVariables in interface VariableManagerOwnerBase

Returns:

the flag indicating whether this object has Variables.

getVariableManager

public VariableValueManager getVariableManager()

Description copied from interface: VariableManagerOwnerBase

Returns this object's current Variable Value Manager. It will return null if Variable Value Manager has been initialized.

When a framework object is first created, its Variable Value Manager may be null. This method does not initialize (create) the Variable Value Manager.

VariableManagerOwnerBase.ensureVariableManager() in contrast, ensures that the Variable Value Manager is initialized (created).

Specified by:

getVariableManager in interface VariableManagerOwnerBase

Returns:

this object's current Variable Value Manager. May return null if one was not yet initialized.

setVariableManager

protected void setVariableManager(VariableValueManager mgr)

Description copied from interface: DiffMergeable

This method is the entry point call when the diffing process begins on the document-level def. This document-level def may perform its setup or preparation operations and then traverse into nested (children) DiffMergeable's. 'this' object is the changed definition.

Specified by:

beginDiffObjects in interface DiffMergeable

Overrides:

beginDiffObjects in class PersistableDefObject

Parameters:

docDef - the document-level definition

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

Returns:

the DifferDetails that has all the details of diff

                                  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 PersistableDefObject

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

applyDiffChildrenPDefComponentOperations

protected void applyDiffChildrenPDefComponentOperations(DifferDetails dif,
                                                        DiffResolver resolver)

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
       }
    }

                                  DifferDetails difDetails)

Description copied from interface: DiffMergeable

Performs diff of scalar values. Typically, scalar attr values are grouped into String, int, and boolean arrays -- one set coming from 'this' definition and the other set coming from orgDef. Then, help methods on DifferBase can be used to diff the attr values and accumulate the details of diff in difDetails.

Here is example code snippet:

    private static final String DIFF_STRING_ELEMS[] =
    {
       "MyStringVal1",
       "MyStringVal2"
    };

    private static final String DIFF_INT_ELEMS[] =
    {
       "MyIntVal",
    }

    public DifferDetails diffContents(DiffMergeable docDef, DiffMergeable orgDef, DifferDetails difDetails)
    {
        orgDefImpl = () orgDef;

       final String editStringValues[] =
       {
          this.getMyStringVal1(),
          this.getMyStringVal2()
       };

       String orgStringValues[] = null;

       if (orgDef != null)
       {
          String orgV[] =
          {
             orgDefImpl.getMyStringVal1(),
             orgDefImpl.getMyStringVal2()
          };

          orgStringValues = orgV;
       }

       final int editIntValues[] =
       {
          this.getMyIntVal(),
       };

       int orgIntValues[] = null;

       if (orgDef != null)
       {
          int orgV[] =
          {
             orgDefImpl.getMyIntVal()
          };

          orgIntValues = orgV;
       }

       difDetails = DifferBase.diffStringArray(this, DIFF_STRING_ELEMS, editStringValues, orgStringValues, difDetails);
       difDetails = DifferBase.diffIntArray(this, DIFF_INT_ELEMS, editIntValues, orgIntValues, difDetails);

       return difDetails;
   }
 

Specified by:

Overrides:

diffContents in class PersistableDefObject

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

applyDiffContents

public void applyDiffContents(DifferDetails dif,
                              DiffResolver resolver)

Description copied from interface: DiffMergeable

When diff/merge operation is requested, we have the following three def objects:

orgDef - original def object (from the branch point) editDef - def object into which changes are to be merge toMergeDef - def object to be merged (source of changes) For sandbox refresh operation, orgDef comes from the branch point, editDef from the sandbox, toMergeDef from the mainline of the repos. With these three defs, we first diff editDef against orgDef, producing editDifDetails.

Similarly, toMergeDef is diffed against orgDef, producing toMergeDifDetails. The diff engine then walks through these two sets of diffs and identifies conflicts. After the conflicts are all resolved, we apply appropriate changes to editDef.

applyDiffContents is called to apply changes to scalar values. dif contains the changed values to be applied to 'this' object. Use sample code like the following:

    public void applyDiffContents(DifferDetails dif, DiffResolver resolver)
    {
       DifferChangeMap detailMap = dif.getDetailMap();
       Object[] updValues;

       // DIFF_STRING_ELEMS from the above example code
       for (int j = 0; j < DIFF_STRING_ELEMS.length; j++)
       {
          if ((updValues = (Object[]) detailMap.getValue(DIFF_STRING_ELEMS[j])) != null)
          {
             switch(j)
             {
             case 0:
                setMyStringVal1((String) updValues[0]);
                break;
             case 1:
                 setMyStringVal2((String) updValues[0]);
                break;
             }
          }
       }

       for (int j = 0; j < DIFF_INT_ELEMS.length; j++)
       {
          if ((updValues = (Object[]) detailMap.getValue(DIFF_INT_ELEMS[j])) != null)
          {
             switch(j)
             {
             case 0:
                setMyIntVal((Integer) updValues[0]);
                break;
