Hi,
I have read the JiBX documentation (very nice) but the differences
between 'extends' versus 'map-as' is not clear to me. Perhaps someone
could help me with this. What is needed seems fairly straightforward,
and I believe JiBX can handle it, I just can't quite figure out what the
mapping should look like.
What would be the best approach to use for mapping this typical class
hierarchy?
Class-A (base class)
Class-B extends Class-A
Class-C extends Class-B
where none of the classes is abstract (they can all occur individually
in the wild) and where the serialized form of a derived class includes
all the properties (elements, attributes etc.) of the extended classes
but does not include the element names of classes that are extended.
Obviously, some form or re-use of the mappings would be useful. Assume
for now that all properties are simple (i.e. no collections or nested
structures).
I hope this is clear enough, but perhaps an example will help. I would
expect it to serialize an instance of Class-C (something) like this:
<element-C attrA1="" attrB1="" attr-C1="" attr-C2="">
<element-A1/>
<element-A2/>
<element-B1/>
<element-B2/>
<element-C1/>
<element-C2/>
</element-C>
and *not* like this, with wrapping element names from classes higher up
the hierarchy:
<element-C attr-C1="" attr-C2="">
<element-A attrA1="">
<element-A1/>
<element-A2/>
</element-A>
<element-B attrB1="">
<element-B1/>
<element-B2/>
</element-B>
<element-C1/>
<element-C2/>
</element-C>
Are there 'best practices' that cover this issue already written up
somewhere? Many thanks in advance.
...Leif
