 org.jgroups.util.List
All known Subclasses: org.jgroups.util.BoundedList, org.jgroups.util.Stack,
| List | | public class List implements Externalizable,Cloneable(Code) | | Doubly-linked list. Elements can be added at head or tail and removed from head/tail.
This class is tuned for element access at either head or tail, random access to elements
is not very fast; in this case use Vector. Concurrent access is supported: a thread is blocked
while another thread adds/removes an object. When no objects are available, removal returns null.
