Support for try-with-resources Statements in ClosableIterator and Models
Implementation of the interface AutoCloseable in ClosableIterator and
Model. This would allow to use Java's [try-with
resources](https://docs.oracle.com/javase/tutorial/essential/exceptions/tryResourceClose.html)
Statements, i.e.:
` // some definitions
String personURI = "http://somewhere/JohnSmith";;
String fullName = "John Smith";
// create an empty Model
try (Model model = ModelFactory.createDefaultModel()) {
// create the resource
Resource johnSmith = model.createResource(personURI);
// add the property
johnSmith.addProperty(VCARD.FN, fullName);
}`
or
` // list the statements in the Model
try (StmtIterator iter = model.listStatements()) {
// print out the predicate, subject and object of each
statement
while (iter.hasNext()) {
Statement stmt = iter.nextStatement(); // get next
statement
Resource subject = stmt.getSubject(); // get the
subject
Property predicate = stmt.getPredicate(); // get the
predicate
RDFNode object = stmt.getObject(); // get the
object
System.out.print(subject.toString());
System.out.print(" " + predicate.toString() + " ");
if (object instanceof Resource) {
System.out.print(object.toString());
} else {
// object is a literal
System.out.print(" \"" + object.toString() + "\"");
}
System.out.println(" .");
}
}`
