Field Detail

EMPTY_MAP

public static final Int2ShortSortedMaps.EmptySortedMap EMPTY_MAP
An empty type-specific sorted map (immutable). It is serializable and cloneable.

Method Detail

singleton

public static Int2ShortSortedMap singleton(int 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 Int2ShortSortedMap singleton(int key,
                                           short value,
                                           IntComparator 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>.

singleton

public static Int2ShortSortedMap singleton(Object key,
                                           Object 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 Int2ShortSortedMap singleton(Object key,
                                           Object value,
                                           IntComparator 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>.

synchronize

public static Int2ShortSortedMap synchronize(Int2ShortSortedMap m)
Returns a synchronized type-specific sorted map backed by the given type-specific sorted map.

Parameters:
m - the sorted map to be wrapped in a synchronized sorted map.
Returns:
a synchronized view of the specified sorted map.

synchronize

public static Int2ShortSortedMap synchronize(Int2ShortSortedMap m,
                                             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.
sync - an object that will be used to synchronize the access to the sorted sorted map.
Returns:
a synchronized view of the specified sorted map.
