public class Byte2ObjectLinkedOpenHashMap<V>
extends AbstractByte2ObjectSortedMap<V>
implements Serializable, Cloneable, Hash
```
A type-specific linked hash map with with a fast, small-footprint implementation.
Instances of this class use a hash table to represent a map. The table is filled up to a specified load factor, and then doubled in size to accommodate new entries. If the table is emptied below one fourth of the load factor, it is halved in size. However, halving is not performed when deleting entries from an iterator, as it would interfere with the iteration process.
Note that clear() does not modify the hash table size. Rather, a family of trimming methods lets you control the size of the table; this is particularly useful if you reuse instances of this class.
Iterators generated by this map will enumerate pairs in the same order in which they have been added to the map (addition of pairs whose key is already present in the set does not change the iteration order). Note that this order has nothing in common with the natural order of the keys. The order is kept by means of a doubly linked list, represented via an array of longs parallel to the table.
This class implements the interface of a sorted map, so to allow easy access of the iteration order: for instance, you can get the first key in iteration order with firstKey() without having to create an iterator; however, this class partially violates the SortedMap contract because all submap methods throw an exception and comparator() returns always null.
Additional methods, such as getAndMoveToFirst(), make it easy to use instances of this class as a cache (e.g., with LRU policy).
The iterators provided by the views of this class using are type-specific list iterators, and can be started at any element which is a key of the map, or a NoSuchElementException exception will be thrown. If, however, the provided element is not the first or last key in the set, the first access to the list index will require linear time, as in the worst case the entire key set must be scanned in iteration order to retrieve the positional index of the starting key. If you use just the methods of a type-specific BidirectionalIterator, however, all operations will be performed in constant time.

    byte2ObjectEntrySet in interface Byte2ObjectSortedMap<V>
    
    Returns:
    
    a type-specific sorted-set view of the mappings contained in this map.

```
public ByteSortedSet keySet()
```
    Description copied from class: AbstractByte2ObjectSortedMap
    
    Returns a type-specific-sorted-set view of the keys of this map.
    The view is backed by the sorted set returned by AbstractByte2ObjectSortedMap.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.

    Description copied from class: AbstractByte2ObjectSortedMap
    
    Returns a type-specific collection view of the values contained in this map.
    The view is backed by the sorted set returned by AbstractByte2ObjectSortedMap.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need.

  - rehash
```
@Deprecated
public boolean rehash()
```
    Deprecated. A no-op.
    
    A no-op for backward compatibility. The kind of tables implemented by this class never need rehashing.
    If you need to reduce the table size to fit exactly this set, use trim().
    
    Returns:
    
    true.
    
    See Also:
    
    trim()
  - trim
```
public boolean trim()
```
    Rehashes the map, making the table as small as possible.
    This method rehashes the table to the smallest size satisfying the load factor. It can be used when the set will not be changed anymore, so to optimize access speed and size.
    If the table size is already the minimum possible, this method does nothing.
    
    Returns:
    
    true if there was enough memory to trim the map.
    
    See Also:
    
    trim(int)
  - trim
```
public boolean trim(int n)
```
    Rehashes this map if the table is too large.
    Let N be the smallest table size that can hold max(n,size()) entries, still satisfying the load factor. If the current table size is smaller than or equal to N, this method does nothing. Otherwise, it rehashes this map in a table of size N.
    This method is useful when reusing maps. Clearing a map leaves the table size untouched. If you are reusing a map many times, you can call this method with a typical size to avoid keeping around a very large table just because of a few large transient maps.
    
    Parameters:
    
    n - the threshold for the trimming.
    
    Returns:
    
    true if there was enough memory to trim the map.

    trim()
  - clone
```
public Byte2ObjectLinkedOpenHashMap<V> clone()
```
    Returns a deep copy of this map.
    This method performs a deep copy of this hash map; the data stored in the map, however, is not cloned. Note that this makes a difference only for object keys.
    
    Overrides:
    
    clone in class Object
    
    Returns:
    
    a deep copy of this map.
  - hashCode
```
public int hashCode()
```
    Returns a hash code for this map. This method overrides the generic method provided by the superclass. Since equals() is not overriden, it is important that the value returned by this method is the same value as the one returned by the overriden method.
    
    Specified by:
    
    hashCode in interface Map<Byte,V>
    
    Overrides:
    
    hashCode in class AbstractByte2ObjectMap<V>
    
    Returns:
    
    a hash code for this map.
