Examples of org.jboss.cache.Cache

org.jboss.cache.Cache
tes with default settings and starts the cache Cache cache = DefaultCacheFactory.getInstance().createCache(); Fqn personRecords = Fqn.fromString("/org/mycompany/personRecords");
Node rootNode = cache.getRoot(); Node personRecordsNode = rootNode.addChild(personRecords);
// now add some person records. Fqn peterGriffin = Fqn.fromString("/peterGriffin"); Fqn stewieGriffin = Fqn.fromString("/stewieGriffin");
// the addChild() API uses relative Fqns Node peter = personRecordsNode.addChild(peterGriffin); Node stewie = personRecordsNode.addChild(stewieGriffin);
peter.put("name", "Peter Griffin"); peter.put("ageGroup", "MidLifeCrisis"); peter.put("homicidal", Boolean.FALSE);
stewie.put("name", "Stewie Griffin"); stewie.put("ageGroup", "Infant"); stewie.put("homicidal", Boolean.TRUE);
peter.getFqn().toString(); // will print out /org/mycompany/personRecords/peterGriffin stewie.getFqn().toString(); // will print out /org/mycompany/personRecords/stewieGriffin
peter.getFqn().getParent().equals(stewie.getFqn().getParent()); // will return true
