public static class ImmutableSortedMap.Builder<K,V> extends ImmutableMap.Builder<K,V>
public static final
maps ("constant maps"). Example:
static final ImmutableSortedMap<Integer, String> INT_TO_WORD =
new ImmutableSortedMap.Builder<Integer, String>(Ordering.natural())
.put(1, "one")
.put(2, "two")
.put(3, "three")
.build();
For small immutable sorted maps, the ImmutableSortedMap.of()
methods are even
more convenient.
Builder instances can be reused - it is safe to call build()
multiple times to build
multiple maps in series. Each map is a superset of the maps created before it.
Constructor and Description |
---|
Builder(Comparator<? super K> comparator)
Creates a new builder.

Modifier and Type | Method and Description |
---|---|
ImmutableSortedMap<K,V> |
build()
Returns a newly-created immutable sorted map.
|
ImmutableSortedMap.Builder<K,V> |
orderEntriesByValue(Comparator<? super V> valueComparator)
Deprecated.
Unsupported by ImmutableSortedMap.Builder.
|
ImmutableSortedMap.Builder<K,V> |
put(K key,
V value)
Associates
key with value in the built map. |
ImmutableSortedMap.Builder<K,V> |
put(Map.Entry<? extends K,? extends V> entry)
Adds the given
entry to the map, making it immutable if necessary. |
ImmutableSortedMap.Builder<K,V> |
putAll(Iterable<? extends Map.Entry<? extends K,? extends V>> entries)
Adds all the given entries to the built map.
|
ImmutableSortedMap.Builder<K,V> |
putAll(Map<? extends K,? extends V> map)
Associates all of the given map's keys and values in the built map.
