Method Detail

equator

public Equator<K> equator()

Description copied from interface: BaseUnsortedMap

Returns the Equator used by this map for equals comparisons and hashCodes

Specified by:

equator in interface BaseUnsortedMap<K,V>

assoc

public PersistentHashMap.MutableHashMap<K,V> assoc(K key,
                                                         V val)

Description copied from interface: MutableMap

Returns a new map with the given key/value added

Specified by:

assoc in interface BaseMap<K,V>

Specified by:

assoc in interface MutableMap<K,V>

entry

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

Description copied from interface: BaseMap

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

Specified by:

entry in interface BaseMap<K,V>

iterator

public UnmodIterator<UnmodMap.UnEntry<K,V>> iterator()

Description copied from interface: UnmodIterable

A one-time use, mutable, not-thread-safe way to get each value of the underling collection in turn. I experimented with various thread-safe alternatives, but the JVM is optimized around iterators so this is the lowest common denominator of collection iteration, even though iterators are inherently mutable.

Specified by:

iterator in interface java.lang.Iterable<K>

Specified by:

iterator in interface UnmodIterable<K>

keyIterator

public UnmodIterator<K> keyIterator()

Specified by:

keyIterator in interface UnmodMap<K,V>

valIterator

public UnmodIterator<V> valIterator()

Specified by:

valIterator in interface UnmodMap<K,V>

without

public final PersistentHashMap.MutableHashMap<K,V> without(K key)

Description copied from interface: MutableMap

Returns a new map with the given key/value removed

Specified by:

without in interface BaseMap<K,V>

Specified by:

without in interface MutableMap<K,V>

immutable

public final PersistentHashMap<K,V> immutable()

Description copied from interface: MutableMap

Returns an immutable version of this mutable map.

Specified by:

immutable in interface MutableMap<K,V>

size

public final int size()

Description copied from interface: Sized

Returns the number of items in this collection or iterable.

Specified by:

size in interface java.util.Map<K,V>

Specified by:

size in interface Sized
