示例1: record_instance

// Return false if the entry could not be recorded on account
// of running out of space required to create a new entry.
bool KlassInfoTable::record_instance(const oop obj) {
  klassOop      k = obj->klass();
  KlassInfoEntry* elt = lookup(k);
  // elt may be NULL if it's a new klass for which we
  // could not allocate space for a new entry in the hashtable.
  if (elt != NULL) {
    elt->set_count(elt->count() + 1);
    elt->set_words(elt->words() + obj->size());
    return true;
