diffContents

public DifferDetails diffContents(DiffMergeable docDef,
                                  DiffMergeable orgDef,
                                  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:

diffContents in interface DiffMergeable

Overrides:

diffContents in class JboAbstractValidator

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;
             }
          }
       }
    }
 

Notice that the index specified in the case statement is the array index of the attr in the String, int, or boolean array.
