    Returns a new builder. The generated builder is equivalent to the builder created by the ImmutableBiMap.Builder constructor.
  - copyOf
```
public static <K,V> ImmutableBiMap<K,V> copyOf(Map<? extends K,? extends V> map)
```
    Returns an immutable bimap containing the same entries as map. If map somehow contains entries with duplicate keys (for example, if it is a SortedMap whose comparator is not consistent with equals), the results of this method are undefined.
    Despite the method name, this method attempts to avoid actually copying the data when it is safe to do so. The exact circumstances under which a copy will or will not be performed are undocumented and subject to change.
    
    Throws:
    
    IllegalArgumentException - if two keys have the same value
    
    NullPointerException - if any key or value in map is null
  - copyOf
```
@Beta
public static <K,V> ImmutableBiMap<K,V> copyOf(Iterable<? extends Map.Entry<? extends K,? extends V>> entries)
```
    Returns an immutable bimap containing the given entries.
    
    Throws:
    
    IllegalArgumentException - if two keys have the same value or two values have the same key
    
    NullPointerException - if any key, value, or entry is null

  - inverse
```
public abstract ImmutableBiMap<V,K> inverse()
```
    Returns the inverse view of this bimap, which maps each of this bimap's values to its associated key. The two bimaps are backed by the same data; any changes to one will appear in the other.
    Note:There is no guaranteed correspondence between the iteration order of a bimap and that of its inverse.
    
    The inverse of an ImmutableBiMap is another ImmutableBiMap.
    
    Specified by:
    
    inverse in interface BiMap<K,V>
    
    Returns:
    
    the inverse view of this bimap
  - values
```
public ImmutableSet<V> values()
```
    Returns an immutable set of the values in this map. The values are in the same order as the parameters used to build this map.
  - forcePut
```
@Deprecated
public V forcePut(K key,
                              V value)
```
    Deprecated. Unsupported operation.
    
    Guaranteed to throw an exception and leave the bimap unmodified.
    
    Specified by:
    
    forcePut in interface BiMap<K,V>
    
    Parameters:
    
    key - the key with which the specified value is to be associated
    
    value - the value to be associated with the specified key
    
    Returns:
    
    the value which was previously associated with the key, which may be null, or null if there was no previous entry
    
    Throws:
    
    UnsupportedOperationException - always
