Method Detail

empty

static <K extends Comparable<? super K>,V> ImmutableNavigableMap<K,V> empty()

Specified by:

empty in interface ImmutableMap<K,V>

Type Parameters:

K - the key type

V - the value type

Returns:

a wrapped tree-based persistent navigable map that is empty

empty

static <K,V> ImmutableNavigableMap<K,V> empty(Comparator<? super K> comparator)

Type Parameters:

K - the key type

V - the value type

Parameters:

comparator - to decide the order of keys

Returns:

a wrapped tree-based persistent navigable map that is empty

singleton

static <K extends Comparable<? super K>,V> ImmutableNavigableMap<K,V> singleton(K key,
                                                                                V value)

Specified by:

singleton in interface ImmutableMap<K,V>

Type Parameters:

K - the key type

V - the value type

Parameters:

key - the key

value - the value

Returns:

a wrapped tree-based persistent navigable map that has a single mapping

updated

ImmutableNavigableMap<K,V> updated(K key,
                                   V value)

Specified by:

updated in interface ImmutableMap<K,V>

Parameters:

key - the key

value - the value

Returns:

a wrapped persistent navigable map that differs from this one in that the given mapping is added (if necessary)

removed

ImmutableNavigableMap<K,V> removed(K key)

Specified by:

removed in interface ImmutableMap<K,V>

Parameters:

key - the key

Returns:

a wrapped persistent navigable map that differs from this one in that the given mapping is removed (if necessary)
