Willem Jiang reassigned CAMEL-5276:
-----------------------------------
Assignee: Willem Jiang
> Wish ObjectHelper wouldn't return false for a node without children
> -------------------------------------------------------------------
>
> Key: CAMEL-5276
> URL: https://issues.apache.org/jira/browse/CAMEL-5276
> Project: Camel
> Issue Type: Wish
> Components: camel-core
> Affects Versions: 2.8.5
> Reporter: Bobby Hargett
> Assignee: Willem Jiang
> Labels: util
>
> org.apache.camel.util.ObjectHelper's method evaluateValuePredicate(Object)
> tests to see if an object of type NodeList has any children. If it doesn't
> have any children it return false?
> What if you have an Element that just has attributes and that is all you
> need? Would it be possible to check if the object passed in is a Node first
> and then check to see if it is a list...
> The offending(?) code
> {noformat}
> /**
> * Evaluate the value as a predicate which attempts to convert the value
> to
> * a boolean otherwise true is returned if the value is not null
> */
> public static boolean evaluateValuePredicate(Object value) {
> if (value instanceof Boolean) {
> return (Boolean)value;
> } else if (value instanceof String) {
> if ("true".equalsIgnoreCase((String)value)) {
> return true;
> } else if ("false".equalsIgnoreCase((String)value)) {
> return false;
> }
> } else if (value instanceof NodeList) { //Test for Node here?
> // is it an empty dom
> NodeList list = (NodeList) value;
> return list.getLength() > 0;
> } else if (value instanceof Collection) {
> // is it an empty collection
> Collection<?> col = (Collection<?>) value;
> return col.size() > 0;
> }
> return value != null;
> }
> {noformat}
