                                             CompoundNameChildCache pathCache) {
        AllValuesQueryProfileVisitor visitor = new AllValuesQueryProfileVisitor(prefix, pathCache);

    }
Adds all objects that start with the given path prefix to the given value map. Use "" to list all.
<p>
For example, if {a.d =&gt; "a.d-value" ,a.e =&gt; "a.e-value", b.d =&gt; "b.d-value", then calling listValues("a")
will return {"d" =&gt; "a.d-value","e" =&gt; "a.e-value"}
