question: return a list of memorydata objects corresponding to the objects that have been registered by #collectable object and have not been garbage-collected properly.this method first calls system.gc multiple times to attempt to force any remaining garbage collection . concode_field_sep WeakReference<Object> reference concode_elem_sep long registrationTime concode_elem_sep int listenerCallCount concode_elem_sep List<MemoryData> objects concode_elem_sep int collectableCallCount concode_elem_sep List<WeakReference<ListenerList<?>>> listenerLists concode_elem_sep int PURGE_CALL_COUNT concode_elem_sep Logger log concode_field_sep void registerListenerList concode_elem_sep long getRegistrationTime concode_elem_sep void purgeListeners concode_elem_sep void collectable concode_elem_sep List<ListenerList<?>> getRemainingListenerLists concode_elem_sep void purgeCollectables concode_elem_sep WeakReference<Object> getReference
target: List < MemoryData > function ( ) { for ( int loc0 = 0 ; loc0 < 5 ; loc0 ++ ) { System . runFinalization ( ) ; System . gc ( ) ; try { Thread . sleep ( 1 ) ; } catch ( InterruptedException loc1 ) { } } purgeCollectables ( ) ; return new ArrayList < MemoryData > ( objects ) ; }
