public class Results
- extends java.util.LinkedHashMap<java.lang.String,java.util.LinkedHashMap<java.lang.String,java.lang.Object>>
This class provides simple methods to access results of the selection.
Results are ordered in a map of map.
Let's say your search returns 3 results:
(uri:mySubject#1, uri:myPredicate#1, resource:myObject#1)
(uri:mySubject#1, uri:myPredicate#2, resource:myObject#2)
(uri:mySubject#2, uri:myPredicate#1, resource:myObject#3)
To access the text value of resource:myObject#1, one could write
Results results = SimpleSelector.searchFor(Mydoc);
String valueOfMyObject1 = results.getTypedValue("uri:mySubject#1","uri:myPredicate#1",String.class);
To list all subjects that contain the predicate uri:myPredicate#1, one could write:
Results results = SimpleSelector.searchFor(Mydoc);
List<String> sujbects = results.getSubjects("uri:myPredicate#1",".*");
Remark: the use of a regular expression in the second parameters allow to select any value for this predicate.
