Class AbstractChildElementIterator
java.lang.Object
org.mule.config.spring.parsers.processors.AbstractChildElementIterator
- All Implemented Interfaces:
- PostProcessor
- Direct Known Subclasses:
- NamedSetterChildElementIterator
public abstract class AbstractChildElementIterator
- extends Object
- implements PostProcessor
This iterates over child elements, parsing them and calling
insertBean(BeanAssembler, Object, Element, Element)
.
There are two ways we can parse a tree of elements - have an external loop or let
each parser iterate over its own children. Mule uses the first strategy, but some
(most? all?) third party BDPs use the second. This processor lets us use third
party beans inside the Mule framework.
So this is a very specialised parser that should only be used when trying to
inter-operate with beans from third party packages which themselves control how
their children are parsed.
Since for Mule beans the iteration over child elements (at least currently) is
done via MuleHierarchicalBeanDefinitionParserDelegate
the calling parser
needs to set the flag
MuleHierarchicalBeanDefinitionParserDelegate.MULE_NO_RECURSE
- this stops
the Mule recursion from working.
NOTE - IMHO (ac) the Mule approach was probably a mistake; this processor could be
used as a way to slowly migrate the Mule code to the more common approach.
