java.lang.Objectorg.eclipse.mat.query.results.ListResult
public class ListResult
A list of items such as properties as a result table. Compare to
PropertyResult
which extracts and displays from a single object.
Example:
int[] objectIds = myClass.getObjectIds();
List pairs = new ArrayList();
// loop over all instances and take the value of the field name and the field value
for (int id : objectIds)
{
IObject myObject = snapshot.getObject(id);
String name = ((IObject) myObject.resolveValue("name")).getClassSpecificName();
String value = ((IObject) myObject.resolveValue("value")).getClassSpecificName();
pairs.add(new NameValuePair(name, value));
}
// the NameValuePair is a bean with two properties - name and value
// the returned result will be a table with two columns - one for each of these properties
return new ListResult(NameValuePair.class, pairs, "name", "value")
