Class AttachmentList<E>

  • All Implemented Interfaces:
    Iterable<E>, Collection<E>, List<E>, RandomAccess
    public final class AttachmentList<E>
extends Object
implements List<E>, RandomAccess
    A List meant for use with an Attachable object. The list has concurrency semantics equivalent to Collections.synchronizedList; i.e. it is thread safe for reads and writes not involving an iterator or stream but if reads can occur concurrently with writes it is imperative that the user manually synchronize on the list when iterating over it: 
     AttachmentList list = new AttachmentList<>();
 ...
 synchronized (list) {
      Iterator i = list.iterator(); // Must be in synchronized block
      while (i.hasNext())
          foo(i.next());
 }
