Interface BaseMap<K,V>

All Superinterfaces:

Iterable<UnmodMap.UnEntry<K,V>>, Map<K,V>, Sized, Transformable<UnmodMap.UnEntry<K,V>>, UnmodIterable<UnmodMap.UnEntry<K,V>>, UnmodMap<K,V>

All Known Subinterfaces:

BaseUnsortedMap<K,V>, ImMap<K,V>, ImSortedMap<K,V>, MutMap<K,V>

All Known Implementing Classes:

public interface BaseMap<K,V>
extends UnmodMap<K,V>

Adds copy-on-write, "fluent interface" methods to UnmodMap. Lowest common ancestor of BaseUnsortedMap, and ImSortedMap.

Method Detail

entry

@NotNull
@NotNull Option<UnmodMap.UnEntry<K,V>> entry(K key)

Returns an option of the key/value pair associated with this key

assoc

@NotNull
@NotNull BaseMap<K,V> assoc(K key,
                                  V val)

Returns a new map with the given key/value added

assoc

@NotNull
default @NotNull BaseMap<K,V> assoc(@NotNull
                                          Map.Entry<K,V> entry)

Returns a new map with an immutable copy of the given entry added

without

@NotNull
@NotNull BaseMap<K,V> without(K key)

Returns a new map with the given key/value removed

entrySet

@NotNull
@NotNull BaseSet<Map.Entry<K,V>> entrySet()

Returns a view of the mappings contained in this map. The set should actually contain UnmodMap.Entry items, but that return signature is illegal in Java, so you'll just have to remember.

Specified by:

entrySet in interface Map<K,V>

Specified by:

entrySet in interface UnmodMap<K,V>

keySet

@NotNull
@NotNull BaseSet<K> keySet()

Returns a view of the keys contained in this map.

Specified by:

keySet in interface Map<K,V>

Specified by:

keySet in interface UnmodMap<K,V>

containsKey

default boolean containsKey(Object key)

Specified by:

containsKey in interface Map<K,V>

get

@Nullable
default V get(Object key)

Specified by:

get in interface Map<K,V>

getOrElse

default V getOrElse(K key,
                    V notFound)
