Method Details
-
fastIterator
- Parameters:
map
- a map from which we will try to extract a (fast) iterator on the entry set.- Returns:
- an iterator on the entry set of the given map that will be fast, if possible.
- Since:
- 8.0.0
-
fastForEach
- Parameters:
map
- a map on which we will try to iterate quickly.consumer
- the consumer that will be passed toShort2ByteMap.FastEntrySet.fastForEach(Consumer)
, if possible, or toIterable.forEach(Consumer)
.- Since:
- 8.1.0
-
fastIterable
Returns an iterable yielding an iterator that will be fast, if possible, on the entry set of the providedmap
.- Parameters:
map
- a map from which we will try to extract an iterable yielding a (fast) iterator on the entry set.- Returns:
- an iterable yielding an iterator on the entry set of the given map that will be fast, if possible.
- Since:
- 8.0.0
-
singleton
Returns a type-specific immutable map containing only the specified pair. The returned map is serializable and cloneable.Note that albeit the returned map is immutable, its default return value may be changed.
- Parameters:
key
- the only key of the returned map.value
- the only value of the returned map.- Returns:
- a type-specific immutable map containing just the pair
<key,value>
.

- Parameters:
key
- the only key of the returned map.value
- the only value of the returned map.- Returns:
- a type-specific immutable map containing just the pair
<key,value>
.
-
synchronize
Returns a synchronized type-specific map backed by the given type-specific map.- Parameters:
m
- the map to be wrapped in a synchronized map.- Returns:
- a synchronized view of the specified map.

-
synchronize
Returns a synchronized type-specific map backed by the given type-specific map, using an assigned object to synchronize.- Parameters:
m
- the map to be wrapped in a synchronized map.sync
- an object that will be used to synchronize the access to the map.- Returns:
- a synchronized view of the specified map.
- See Also:
-
unmodifiable
Returns an unmodifiable type-specific map backed by the given type-specific map.- Parameters:
m
- the map to be wrapped in an unmodifiable map.- Returns:
- an unmodifiable view of the specified map.
