Displaying derived properties in the UI is similar to displaying regular properties.
The Presentation API’s semantics for a derived property are similar to those of regular properties, though there are a few differences. Derived properties apply only to aggregated Oracle Commerce records. Therefore, the MDEX Engine query must be properly formulated to include a rollup key.
Use the following calls to work with the aggregated record (an AggERec object):
|

The following code examples demonstrate how to display the names and values of an aggregated record’s derived properties.
Example 55. Java example of displaying derived properties
// Get aggregated record list
AggrERecList aggrecs = nav.getAggrERecs();
for (int i=0; i<aggrecs.size(); i++) {
// Get individual aggregated record
AggrERec aggrec = (AggrERec)aggrecs.get(i);
// Get all derived properties.
PropertyMap derivedProps = aggrRec.getProperties();
Iterator derivedPropIter = derivedProps.entrySet().iterator();
// Loop over each derived property,
// handle as an ordinary property.
while (derivedPropIter.hasNext()) {
Property prop = (Property) derivedPropIter.next( );
// Display property
%>
<tr>
<td>Derived property name: <%= prop.getKey() %></td>
<td>Derived property value: <%= prop.getValue() %></td>
</tr>
<%
}
}
Example 56. .NET example of displaying derived properties
Get aggregated record list
AggrERecList aggrecs = nav.AggrERecs;
// Loop over aggregated record list
for (int i=0; i<aggrecs.Count; i++) {
// Get an individual aggregated record
AggrERec aggrec = (AggrERec)aggrecs[i];
// Get all derived properties.
PropertyMap derivedPropsMap = aggrec.Properties;
// Get property list for agg record
System.Collections.IList derivedPropsList = derivedPropsMap.EntrySet;
// Loop over each derived property,
// handle as an ordinary property.
foreach (Property derivedProp in derivedPropsList) {
// Display property
%>
<tr><td>Derived property name: <%= derivedProp.Key %></td>
<td>Derived property value: <%= derivedProp.Value %></td></tr>
<%
}
}
