NodeValueIterator Class Reference

Detailed Description

NodeValueIterator is used to iterate over all persistent values of a Node (not including relations).

The following example shows the usage:

// load the node with depth 10
$node = ObjectFactory::getInstance('persistenceFacade')->load(new ObjectId('Page', 300), 10);
 
// iterate over all values
$it = new NodeValueIterator($node);
foreach($it as $name => $value) {
  echo("current attribute name: ".$name);
  echo("current attribute value: ".$value);
}
 
// iterate over all values with access to the current object
for($it->rewind(); $it->valid(); $it->next()) {
  echo("current object: ".$it->currentNode());
  echo("current attribute name: ".$it->key());
  echo("current attribute value: ".$it->current());
}
