@GwtCompatible(serializable=true,
               emulated=true)
public class ImmutableListMultimap<K,V>
extends ImmutableMultimap<K,V>
implements ListMultimap<K,V>
```
An immutable ListMultimap with reliable user-specified key and value iteration order. Does not permit null keys or values.
Unlike Multimaps.unmodifiableListMultimap(ListMultimap), which is a view of a separate multimap which can still change, an instance of ImmutableListMultimap contains its own data and will never change. ImmutableListMultimap is convenient for public static final multimaps ("constant multimaps") and also lets you easily make a "defensive copy" of a multimap provided to your class by a caller.
Note: Although this class is not final, it cannot be subclassed as it has no public or protected constructors. Thus, instances of this class are guaranteed to be immutable.
See the Guava User Guide article on immutable collections.

    Returns an immutable multimap containing the given entries, in order.
  - builder
```
public static <K,V> ImmutableListMultimap.Builder<K,V> builder()
```
    Returns a new builder. The generated builder is equivalent to the builder created by the ImmutableListMultimap.Builder constructor.
  - copyOf
```
public static <K,V> ImmutableListMultimap<K,V> copyOf(Multimap<? extends K,? extends V> multimap)
```
    Returns an immutable multimap containing the same mappings as multimap. The generated multimap's key and value orderings correspond to the iteration ordering of the multimap.asMap() view.
    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:
    
    NullPointerException - if any key or value in multimap is null
  - get
```
public ImmutableList<V> get(@Nullable
                            K key)
```
    Returns an immutable list of the values for the given key. If no mappings in the multimap have the provided key, an empty immutable list is returned. The values are in the same order as the parameters used to build this multimap.

    Parameters:
    
    key - key to search for in multimap
    
    Returns:
    
    a view collection containing the zero or more values that the key maps to
  - inverse
```
public ImmutableListMultimap<V,K> inverse()
```
    Returns an immutable multimap which is the inverse of this one. For every key-value mapping in the original, the result will have a mapping with key and value reversed.
    Because an inverse of a list multimap can contain multiple pairs with the same key and value, this method returns an ImmutableListMultimap rather than the ImmutableMultimap specified in the ImmutableMultimap class.

    the collection of removed values, or an empty collection if no values were associated with the provided key. The collection may be modifiable, but updating it will have no effect on the multimap.

  - isEmpty

public boolean isEmpty()

    Description copied from interface: Multimap

                             @Nullable
                             Object value)
```
    Description copied from interface: Multimap
    
    Returns true if the multimap contains the specified key-value pair.
    
    Specified by:
    
    containsEntry in interface Multimap<K,V>
    
    Parameters:
    
    key - key to search for in multimap
    
    value - value to search for in multimap
  - equals
```
public boolean equals(@Nullable
                      Object object)
```
    Description copied from interface: Multimap
    
    Compares the specified object with this multimap for equality. Two multimaps are equal when their map views, as returned by Multimap.asMap(), are also equal.
    In general, two multimaps with identical key-value mappings may or may not be equal, depending on the implementation. For example, two SetMultimap instances with the same key-value mappings are equal, but equality of two ListMultimap instances depends on the ordering of the values for each key.
    A non-empty SetMultimap cannot be equal to a non-empty ListMultimap, since their Multimap.asMap() views contain unequal collections as values. However, any two empty multimaps are equal, because they both have empty Multimap.asMap() views.
    
    Specified by:
    
    equals in interface Multimap<K,V>
    
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Returns the hash code for this multimap.
    The hash code of a multimap is defined as the hash code of the map view, as returned by Multimap.asMap().
    
    Specified by:
    
    hashCode in interface Multimap<K,V>

    hashCode in class Object

  - toString
```
public String toString()
```
    Returns a string representation of the multimap, generated by calling toString on the map returned by Multimap.asMap().
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of the multimap
