Examples of org.exist.xquery.value.Item.convertTo()

org.exist.xquery.value.Item.convertTo()
Convert this item into an atomic value, whose type corresponds to the specified target type. requiredType should be one of the type constants defined in {@link Type}. An {@link XPathException} is thrownif the conversion is impossible. @param requiredType @throws XPathException

          final Item item = seq.itemAt(0);
          NumericValue value;
          if (item instanceof NumericValue) {
        value = (NumericValue) item;
      } else {
        value = (NumericValue) item.convertTo(Type.NUMBER);
      }
            result = value.ceiling();
        }
        if (context.getProfiler().isEnabled()) 
            {context.getProfiler().end(this, "", result);}
