Class SynchronizedLinkedMap<K,V>
- Type Parameters:
K
-V
-
"Pseudo" because this class does not implement the map interface, for the primary reason that
iterators on keys/values/items would not abide by the contract requested by Map
(mostly,
that modifying the entries while iterating also modifies the backing map). Note that this class
offers a #copyOfKeySet()
method which can safely be used to iterate the keys of the map
at the time that method was executed. Modifying that set does not impact the map itself. Unlike
synchronized maps provided by Collections
, there is no
need to synchronize when iterating over the Collection returned by copyOfKeySet().
Similarly to ConcurrentHashMap
(but unlike LinkedHashMap
), this class does not
allow null key or null value.
Methods of this object are guaranteed to never raise ConcurrentModificationException
.
