示例1:

{
JS_ASSERT(!child->inDictionary());
JS_ASSERT(child->parent == this);
KidsPointer *kidp = &kids;
if (kidp->isShape()) {
JS_ASSERT(kidp->toShape() == child);
kidp->setNull();
child->parent = NULL;
return;
}
KidsHash *hash = kidp->toHash();
JS_ASSERT(hash->count() >= 2); /* otherwise kidp->isShape() should be true */
hash->remove(child);
child->parent = NULL;
if (hash->count() == 1) {
/* Convert from HASH form back to SHAPE form. */
KidsHash::Range r = hash->all();
Shape *otherChild = r.front();
JS_ASSERT((r.popFront(), r.empty())); /* No more elements! */
kidp->setShape(otherChild);
js_delete(hash);
}
