ParFlatHashTable

Add elem if not yet in table.

Checks whether an element is contained in the hash table.

Elems have type A, but we store AnyRef in the table. Plus we need to deal with null elems, which need to be stored as NullSentinel

Does the inverse translation of elemToEntry

Finds an entry in the hash table if such an element exists.

Initializes the collection from the input stream. f will be called for each element read from the input stream in the order determined by the stream. This is useful for structures where iteration order is important (e.g. LinkedHashSet).

The serialization format expected is the one produced by serializeTo.

The initial size of the hash table.

Removes an elem from the hash table returning true if the element was found (and thus removed) or false if it didn't exist.

Serializes the collection to the output stream by saving the load factor, collection size and collection elements. foreach determines the order in which the elements are saved to the stream. To deserialize, init should be used.

The actual hash table.
