In my sandbox, I implemented InspectableSource in JCRNodeSource
(I already posted a message some time ago).
can you send that to me that I can give it a try
I attached the additional methods below.
To compile it, you have to add the dependency from the JCR
block to the repository block in gump.xml and enable the blocks
in local.blocks.properties.
How do you imagine providing access to the properties?
Property getProperty(...) {
return getNode().getProperty(...);
}
doesn't add much value ...
what do you mean by doesn't add much value?
Because getNode() can be called by the client code as well:
((JCRNodeSource) source).getNode().getProperty()
instead of
((JCRNodeSource) source).getProperty()
Now such a source, you can get the corresponding Node and then do
whatever you want with it.
yes, I can list all nodes by using the TraversableGenerator, but I
think it
would make sense it the the JCR Source in combination with the
"FileGenerator"
would allow to get the content of a JCR property, e.g.
<property name="" value="">
....
</property>
That could probably be implemented using an
"InspectableTraversableGenerator"
or something like that ...
Well, I think it would make sense to stick to the source and map nodes
onto collections and properties onto resources.
Do you mean something like that?
node <-> directory
property <-> file
That would certainly make sense, because it allows to resemble arbitrary
JCR repos using a file system.
