Class ImmutableSetMultimap<K,V>

java.lang.Object
com.google.common.collect.ImmutableMultimap<K,V>
com.google.common.collect.ImmutableSetMultimap<K,V>
All Implemented Interfaces:
Multimap<K,V>, SetMultimap<K,V>, Serializable
@GwtCompatible(serializable=true, emulated=true) @Deprecated(since="2022-12-01") public class ImmutableSetMultimap<K,V> extends ImmutableMultimap<K,V> implements SetMultimap<K,V>
Deprecated.
The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023
An immutable SetMultimap with reliable user-specified key and value iteration order. Does not permit null keys or values.

Unlike Multimaps.unmodifiableSetMultimap(SetMultimap), which is a view of a separate multimap which can still change, an instance of ImmutableSetMultimap contains its own data and will never change. ImmutableSetMultimap 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.

      Deprecated.

      Deprecated.
      Returns an immutable multimap containing the given entries, in order. Repeated occurrences of an entry (according to Object.equals(java.lang.Object)) after the first are ignored.

      Deprecated.
      Returns an immutable multimap containing the given entries, in order. Repeated occurrences of an entry (according to Object.equals(java.lang.Object)) after the first are ignored.

    • builder

      public static <K, V> ImmutableSetMultimap.Builder<K,V> builder()
      Deprecated.
      Returns a new ImmutableSetMultimap.Builder.

    • copyOf

      public static <K, V> ImmutableSetMultimap<K,V> copyOf(Multimap<? extends K,? extends V> multimap)
      Deprecated.
      Returns an immutable set 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. Repeated occurrences of an entry in the multimap after the first are ignored.

      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 ImmutableSet<V> get(@Nullable K key)
      Deprecated.
      Returns an immutable set of the values for the given key. If no mappings in the multimap have the provided key, an empty immutable set is returned. The values are in the same order as the parameters used to build this multimap.
      Specified by:
      get in interface Multimap<K,V>
      Specified by:
      get in interface SetMultimap<K,V>
      Specified by:
      get in class ImmutableMultimap<K,V>
      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 ImmutableSetMultimap<V,K> inverse()
      Deprecated.
      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 set multimap cannot contain multiple pairs with the same key and value, this method returns an ImmutableSetMultimap rather than the ImmutableMultimap specified in the ImmutableMultimap class.

      Specified by:
      inverse in class ImmutableMultimap<K,V>

      Parameters:
      key - key of entries to remove from the multimap
      Returns:
      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.
      Throws:
      UnsupportedOperationException - always

      Parameters:
      key - key to store in the multimap
      values - values to store in the multimap
      Returns:
      the collection of replaced values, or an empty collection if no values were previously associated with the key. The collection may be modifiable, but updating it will have no effect on the multimap.

    • entries

      public ImmutableSet<Map.Entry<K,V>> entries()
      Deprecated.
      Returns an immutable collection of all key-value pairs in the multimap. Its iterator traverses the values for the first key, the values for the second key, and so on.

    • isEmpty

      public boolean isEmpty()
      Deprecated.

    • containsEntry

      public boolean containsEntry(@Nullable Object key, @Nullable Object value)

      Parameters:
      key - key to search for in multimap
      value - value to search for in multimap

    • equals

      public boolean equals(@Nullable Object object)
      Deprecated.
      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.

      equals in interface Multimap<K,V>
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      Deprecated.
      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>
      Overrides:

      Returns:
      a string representation of the multimap
