<p>Hello Keith,</p>
<p><br>
</p>
<p>yes, I'll be glad to do that. The deltas have been traditionally
created using <tt>ContainerDelta.xyz</tt> methods, now migrated
to <tt>prismContext.deltaFactory().container().xyz</tt> methods
almost in 1:1 way. This is what Nico has used. This API is fully
functional, but - in my opinion - quite complicated.</p>
<p><br>
</p>
<p>Therefore, about 4 years ago, the <i>delta builder</i> was
created as a simple yet powerful mechanism for easy creation of
deltas - both object deltas and item deltas. It uses a fluent API
to construct them, like</p>
<p><br>
</p>
<p><tt>prismContext.deltaFor(CaseType.class)</tt><tt><br>
</tt><tt>
.item(CaseType.F_STATE).replace(SchemaConstants.CASE_STATE_CLOSED)</tt><tt><br>
</tt><tt>
.item(CaseType.F_CLOSE_TIMESTAMP).replace(now)</tt><tt><br>
</tt><tt> .asItemDeltas()</tt><tt><br>
</tt></p>
<p><br>
</p>
<p>There are numerous examples of this API throughout midPoint
source code: about 360 usages in production code and about 260
usages in test code. But I am afraid I still didn't had the time
to write a documentation. Anyway, I am quite sure the interface is
really self-explanatory and simple.</p>
<p><br>
</p>
<p>In midPoint 4.0 the interface of obtaining the delta builder was
slightly changed from (e.g.) <code>DeltaBuilder.deltaFor(UserType.class,
prismContext)</code> to <code>prismContext.deltaFor(UserType.class)</code>;
however, the rest of API is still the same.<br>
</p>
<p><br>
</p>
<p>As the comparison of these two is concerned, I think the delta
builder is the way to go in 99 percent of cases. Maybe if you'd
need something really high-performant (squeezing out fractions of
microseconds, figurately speaking), you could go for the original
way.<br>
</p>
<p><br>
</p>
<p>Maybe someone could supplement or correct me :)</p>
<p><br>
</p>
<p>(Well, actually, we'd be grateful for any comments of both delta
and query builder API; or midPoint internal APIs in general.)</p>
<p><br>
</p>
<p>Best regards and nice weekend!<br>

<div>Hi Pavol,</div>
<div>thanks for the link. I have get it working now.</div>
<div>This is what i changed:</div>
<div>Old pre v4.0:</div>
<div>assignmentDelta =
ContainerDelta.createModificationAdd(UserType.F_ASSIGNMENT,
UserType, prismContext, assignment);</div>
<div>New:</div>
<div>assignmentDelta =
prismContext.deltaFactory().container().createModificationAdd(UserType.F_ASSIGNMENT,

<p>Hello Nico,</p>
<p>you're right. The wiki should be (eventually)
updated.<br>
</p>
<p>In the meanwhile please see <a

For delta creation, the delta builder is the correct
way to go.</p>

<div>i have updated our midpoint testsystem from 3.8

<div>And now i have an error occurs in the scripted

<div><code>This is not working anymore in 4.0.
