I understand the difference between the Sling Resource Type and the JCR
Node type. However the resource.isResourceType is not specifically
dealing with one or the other. If I had a resource of a node with a
primaryNodeType of nt:file then doing resource.isResourceType("nt:file")
would return true.
I had to dig through the code to see what was going on.
The basic idea is that calling resource.getResourceType() will return
the sling:resourceType and if that's not there then it will return the
jcr:primaryType. When calling "isResourceType" it will compare against
the resource.getResourceType() and if that's not a match will march of
the chain of getSuperResourceType looking for a match, and that matches
only against the sling:resourceType.
I can sorta see where that's useful from a script resolution point of
view. I find it odd overall as it's missing out on a section of
inheritance. It's like having a java instanceof operator ignoring
interfaces.
