    • Method Detail

      • entryComparator

        public static Comparator<? super Map.Entry<Long,​?>> entryComparator​(LongComparator 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<Long2ShortMap.Entry> fastIterator​(Long2ShortSortedMap map)
        Returns a bidirectional iterator that will be fast, if possible, on the entry set of the provided map.
        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.

      • fastIterable

        public static ObjectBidirectionalIterable<Long2ShortMap.Entry> fastIterable​(Long2ShortSortedMap map)
        Returns an iterable yielding a bidirectional iterator that will be fast, if possible, on the entry set of the provided map.
        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.

      • singleton

        public static Long2ShortSortedMap singleton​(Long 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 &lt;key,value&gt;.

                                                    LongComparator 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 &lt;key,value&gt;.

        Returns a type-specific immutable sorted map containing only the specified pair. The returned sorted map is serializable and cloneable.

        Parameters:
        key - the only key of the returned sorted map.
        value - the only value of the returned sorted map.
        Returns:

                                                      Object sync)
        Returns a synchronized type-specific sorted map backed by the given type-specific sorted map, using an assigned object to synchronize.
        Parameters:
        m - the sorted map to be wrapped in a synchronized sorted map.
