Constructor and Description
ObservableSelfPopulatingMap(Map<K,V> delegate, BiPredicate<K,V> beforePutValidator, BiConsumer<K,V> onPutAction, Function<K,V> onGetPopulatorAction)

Method Summary

Modifier and Type	Method and Description
void	clear()
V	compute(K key, BiFunction<? super K,? super V,? extends V> remappingFunction) Same approach as computeIfAbsent: validate inside the remapping function so that a rejection prevents the value from ever reaching the delegate.
V	computeIfAbsent(K key, Function<? super K,? extends V> mappingFunction) Validation happens before the value is written to the delegate by wrapping the mapping function so we can intercept the produced value first.
boolean	containsKey(Object key)
boolean	containsValue(Object value)
Set<Map.Entry<K,V>>	entrySet()
V	get(Object key) If a populator was provided and the key is missing, produces a value, stores it (triggering validation + notification), and returns it.
boolean	isEmpty()
Set<K>	keySet()
V	merge(K key, V value, BiFunction<? super V,? super V,? extends V> remappingFunction)
V	put(K key, V value)
void	putAll(Map<? extends K,? extends V> map)
V	putIfAbsent(K key, V value)
V	remove(Object key)
int	size()
Collection<V>	values()

ObservableSelfPopulatingMap

public ObservableSelfPopulatingMap(Map<K,V> delegate,
                                   BiPredicate<K,V> beforePutValidator,
                                   BiConsumer<K,V> onPutAction,
                                   Function<K,V> onGetPopulatorAction)

Method Detail

put

public V put(K key,
             V value)

Specified by:

put in interface Map<K,V>

putAll

public void putAll(Map<? extends K,? extends V> map)

Specified by:

putAll in interface Map<K,V>

putIfAbsent

public V putIfAbsent(K key,
                     V value)

Specified by:

putIfAbsent in interface Map<K,V>

computeIfAbsent

public V computeIfAbsent(K key,
                         Function<? super K,? extends V> mappingFunction)

Validation happens before the value is written to the delegate by wrapping the mapping function so we can intercept the produced value first.

Specified by:

computeIfAbsent in interface Map<K,V>

compute

public V compute(K key,
                 BiFunction<? super K,? super V,? extends V> remappingFunction)

Same approach as computeIfAbsent: validate inside the remapping function so that a rejection prevents the value from ever reaching the delegate.

Specified by:

compute in interface Map<K,V>

merge

public V merge(K key,
               V value,
               BiFunction<? super V,? super V,? extends V> remappingFunction)

Specified by:

merge in interface Map<K,V>

get

public V get(Object key)

If a populator was provided and the key is missing, produces a value, stores it (triggering validation + notification), and returns it.

Specified by:

get in interface Map<K,V>

containsKey

public boolean containsKey(Object key)

Specified by:

containsKey in interface Map<K,V>

size

public int size()

Specified by:

size in interface Map<K,V>

isEmpty

Specified by:

containsValue in interface Map<K,V>

remove

public V remove(Object key)

Specified by:

remove in interface Map<K,V>

clear

public void clear()

Specified by:

clear in interface Map<K,V>

keySet

public Set<K> keySet()

Specified by:

keySet in interface Map<K,V>

values

public Collection<V> values()

Specified by:

values in interface Map<K,V>
