Class ImmutableListMultimap.Builder<K,V>

java.lang.Object

com.diffplug.common.collect.ImmutableMultimap.Builder<K,V>

com.diffplug.common.collect.ImmutableListMultimap.Builder<K,V>

Enclosing class:

ImmutableListMultimap<K,V>

public static final class ImmutableListMultimap.Builder<K,V>
extends ImmutableMultimap.Builder<K,V>

A builder for creating immutable ListMultimap instances, especially public static final multimaps (“constant multimaps”). Example:

 

  static final Multimap<String, Integer> STRING_TO_INTEGER_MULTIMAP =
      new ImmutableListMultimap.Builder<String, Integer>()
          .put("one", 1)
          .putAll("several", 1, 2, 3)
          .putAll("many", 1, 2, 3, 4, 5)
          .build();

Builder instances can be reused; it is safe to call build() multiple times to build multiple multimaps in series. Each multimap contains the key-value mappings in the previously created multimaps.

2.0

Builder

public Builder()

Creates a new builder. The returned builder is equivalent to the builder generated by ImmutableListMultimap.builder().

Method Detail

put

public ImmutableListMultimap.Builder<K,V> put(K key,
                                              V value)

Description copied from class: ImmutableMultimap.Builder

Adds a key-value mapping to the built multimap.

Overrides:

put in class ImmutableMultimap.Builder<K,V>

put

public ImmutableListMultimap.Builder<K,V> put(Map.Entry<? extends K,? extends V> entry)

Adds an entry to the built multimap.

Overrides:

put in class ImmutableMultimap.Builder<K,V>

Since:

11.0

putAll

@Beta
public ImmutableListMultimap.Builder<K,V> putAll(Iterable<? extends Map.Entry<? extends K,? extends V>> entries)

Adds entries to the built multimap.

Overrides:

putAll in class ImmutableMultimap.Builder<K,V>

Since:

19.0

putAll

public ImmutableListMultimap.Builder<K,V> putAll(K key,
                                                 Iterable<? extends V> values)

Description copied from class: ImmutableMultimap.Builder

Stores a collection of values with the same key in the built multimap.

Overrides:

putAll in class ImmutableMultimap.Builder<K,V>

putAll

public ImmutableListMultimap.Builder<K,V> putAll(K key,
                                                 V... values)

Description copied from class: ImmutableMultimap.Builder

Stores an array of values with the same key in the built multimap.

Overrides:

putAll in class ImmutableMultimap.Builder<K,V>

putAll

public ImmutableListMultimap.Builder<K,V> putAll(Multimap<? extends K,? extends V> multimap)

Description copied from class: ImmutableMultimap.Builder

Stores another multimap’s entries in the built multimap. The generated multimap’s key and value orderings correspond to the iteration ordering of the multimap.asMap() view, with new keys and values following any existing keys and values.

Overrides:

putAll in class ImmutableMultimap.Builder<K,V>

orderKeysBy

public ImmutableListMultimap.Builder<K,V> orderKeysBy(Comparator<? super K> keyComparator)

Specifies the ordering of the generated multimap’s keys.

Overrides:

orderKeysBy in class ImmutableMultimap.Builder<K,V>

Since:

8.0

orderValuesBy

public ImmutableListMultimap.Builder<K,V> orderValuesBy(Comparator<? super V> valueComparator)

Specifies the ordering of the generated multimap’s values for each key.

Overrides:

orderValuesBy in class ImmutableMultimap.Builder<K,V>

Since:

8.0

build

public ImmutableListMultimap<K,V> build()

Returns a newly-created immutable list multimap.

Overrides:
