Class Overview

A serializable, inefficient, fully synchronized, linked pseudo-map. The insertion order is maintained.

"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.
