示例1: do_card_ptr
bool do_card_ptr(jbyte* card_ptr, int worker_i) {
// Construct the region representing the card.
HeapWord* start = _ct_bs->addr_for(card_ptr);
// And find the region containing it.
HeapRegion* r = _g1->heap_region_containing(start);
assert(r != NULL, "unexpected null");
// Scan oops in the card looking for references into the collection set
HeapWord* end = _ct_bs->addr_for(card_ptr + 1);
MemRegion scanRegion(start, end);
UpdateRSetImmediate update_rs_cl(_g1->g1_rem_set());
FilterIntoCSClosure update_rs_cset_oop_cl(NULL, _g1, &update_rs_cl);
FilterOutOfRegionClosure filter_then_update_rs_cset_oop_cl(r, &update_rs_cset_oop_cl);
// We can pass false as the "filter_young" parameter here as:
// * we should be in a STW pause,
// * the DCQS to which this closure is applied is used to hold
// references that point into the collection set from the prior
// RSet updating,
// * the post-write barrier shouldn't be logging updates to young
// regions (but there is a situation where this can happen - see
// the comment in G1RemSet::concurrentRefineOneCard below -
// that should not be applicable here), and
// * during actual RSet updating, the filtering of cards in young
// regions in HeapRegion::oops_on_card_seq_iterate_careful is
// employed.
// As a result, when this closure is applied to "refs into cset"
// DCQS, we shouldn't see any cards in young regions.
update_rs_cl.set_region(r);
HeapWord* stop_point =
r->oops_on_card_seq_iterate_careful(scanRegion,
&filter_then_update_rs_cset_oop_cl,
false /* filter_young */);
// Since this is performed in the event of an evacuation failure, we
// we shouldn't see a non-null stop point
