Method Detail
-
entryComparator
public static Comparator<? super Map.Entry<Character,?>> entryComparator(CharComparator comparator)
Returns a comparator for entries based on a given comparator on keys.- Parameters:
comparator
- a comparator on keys.- Returns:
- the associated comparator on entries.
-
fastIterator
public static ObjectBidirectionalIterator<Char2ShortMap.Entry> fastIterator(Char2ShortSortedMap map)
Returns a bidirectional 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 a (fast) bidirectional iterator on the entry set.- Returns:
- a bidirectional iterator on the entry set of the given map that will be fast, if possible.
- Since:
- 8.0.0
-
fastIterable
public static ObjectBidirectionalIterable<Char2ShortMap.Entry> fastIterable(Char2ShortSortedMap map)
Returns an iterable yielding a bidirectional 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) bidirectional iterator on the entry set.- Returns:
- an iterable yielding a bidirectional iterator on the entry set of the given map that will be fast, if possible.
- Since:
- 8.0.0
-
singleton
public static Char2ShortSortedMap singleton(Character key, Short value)
Returns a type-specific immutable sorted map containing only the specified pair. The returned sorted 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 sorted map.value
- the only value of the returned sorted map.- Returns:
- a type-specific immutable sorted map containing just the pair
<key,value>
.
-
singleton
public static Char2ShortSortedMap singleton(Character key, Short value, CharComparator comparator)
RETURNS a type-specific immutable sorted map containing only the specified pair. The returned sorted 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 sorted map.value
- the only value of the returned sorted map.comparator
- the comparator to use in the returned sorted map.- Returns:
- a type-specific immutable sorted map containing just the pair
<key,value>
.
