示例1: oop_oop_iterate
int klassKlass::oop_oop_iterate(oop obj, OopClosure* blk) {
// Get size before changing pointers
int size = oop_size(obj);
Klass* k = Klass::cast(klassOop(obj));
blk->do_oop(k->adr_super());
for (juint i = 0; i < Klass::primary_super_limit(); i++)
blk->do_oop(k->adr_primary_supers()+i);
blk->do_oop(k->adr_secondary_super_cache());
blk->do_oop(k->adr_secondary_supers());
blk->do_oop(k->adr_java_mirror());
blk->do_oop(k->adr_name());
// The following are in the perm gen and are treated
// specially in a later phase of a perm gen collection; ...
assert(oop(k)->is_perm(), "should be in perm");
assert(oop(k->subklass())->is_perm_or_null(), "should be in perm");
assert(oop(k->next_sibling())->is_perm_or_null(), "should be in perm");
// ... don't scan them normally, but remember this klassKlass
// for later (see, for instance, oop_follow_contents above
// for what MarkSweep does with it.
if (blk->should_remember_klasses()) {
blk->remember_klass(k);
}
obj->oop_iterate_header(blk);
return size;
}示例2: while
// Return self, except for abstract classes with exactly 1
// implementor. Then return the 1 concrete implementation.
Klass *Klass::up_cast_abstract() {
Klass *r = this;
while( r->is_abstract() ) { // Receiver is abstract?
Klass *s = r->subklass(); // Check for exactly 1 subklass
if( !s || s->next_sibling() ) // Oops; wrong count; give up
return this; // Return 'this' as a no-progress flag
r = s; // Loop till find concrete class
}
return r; // Return the 1 concrete class
}
