Subject [jira] Created: (JCR-1396) DateValue.getDate not a copy
Date Tue, 19 Feb 2008 13:04:45 GMT
DateValue.getDate not a copy
----------------------------

                 Key: JCR-1396
                 URL: https://issues.apache.org/jira/browse/JCR-1396
             Project: Jackrabbit
          Issue Type: Bug
          Components: jackrabbit-jcr-commons
    Affects Versions: 1.4
         Environment: any
            Reporter: Sebastian Prehn


I noticed that getDate() in org.apache.jackrabbit.value.DateValue is returned 
by reference. According to the specification it should be a copy. (see.  JSR 170 section 6.2.7)

 
 private Calendar date;
 
 public Calendar getDate()
             throws ValueFormatException, IllegalStateException,
             RepositoryException {
         setValueConsumed();
 
         if (date != null) {
             return date; // <-- HERE
         } else {
             throw new ValueFormatException("empty value");
         }
     }

short test:

ValueFactory factory = session.getValueFactory();
 Value v = factory.createValue(GregorianCalendar.getInstance());
 Calendar c0 = v.getDate();   
 Calendar c1 = v.getDate();
               
 if(c0 == c1){
                   out.println("error - references are equal");
                    out.println(c0);
 }
