Class ConcurrentList<E>
java.lang.Object
com.cedarsoftware.util.ConcurrentList<E>
- All Implemented Interfaces:
Iterable<E>
,Collection<E>
,List<E>
ConcurrentList provides a List and List wrapper that is thread-safe, usable in highly concurrent
environments. It provides a no-arg constructor that will directly return a ConcurrentList that is
thread-safe. It has a constructor that takes a List argument, which will wrap that List and make it
thread-safe (no elements are duplicated).
The iterator(), listIterator() return read-only views copied from the list. The listIterator(index) is not implemented, as the inbound index could already be outside the lists position due to concurrent edits. Similarly, subList(from, to) is not implemented because the boundaries may exceed the lists size due to concurrent edits.
