Overview

A NodeFilter backed by a live JS object implementing the callback interface ({ acceptNode }). TreeWalker/NodeIterator treat it as the filter callable; each invocation runs acceptNode on the JS object (this = object), and the raising variant lets the filter's exception propagate out of the traversal.
