Summary:
I'm sure there's a better way to describe what this does in the Javadoc, but I
can't really come up with one.
Also inlined one method which made another call which is now redundant.
I'd also really like to make this call entirely unnecessary by moving the logic
to `resolve()` so that overriding it automatically implies `canResolve` but the
edge cases for commonProps and treeProps make this rather unpleasant.
