AbstractMutableMapIterable() |
| Modifier and Type | Method and Description |
|---|---|
V |
add(Pair<K,V> keyValuePair)
This method allows mutable map the ability to add an element in the form of Pair
|
<K2,V2> MutableMap<K2,V2> |
aggregateBy(Function<? super V,? extends K2> groupBy,
Function0<? extends V2> zeroValueFactory,
Function2<? super V2,? super V,? extends V2> nonMutatingAggregator)
Applies an aggregate function over the iterable grouping results into a map based on the specific groupBy function.
|
<K2,V2> MutableMap<K2,V2> |
aggregateInPlaceBy(Function<? super V,? extends K2> groupBy,
Function0<? extends V2> zeroValueFactory,
Procedure2<? super V2,? super V> mutatingAggregator)
Applies an aggregate procedure over the iterable grouping results into a Map based on the specific groupBy function.
|
<K2,V2> MutableMap<K2,V2> |
collect(Function2<? super K,? super V,Pair<K2,V2>> function)
For each key and value of the map the function is evaluated.
|
Pair<K,V> |
detect(Predicate2<? super K,? super V> predicate)
Return the first key and value of the map for which the predicate evaluates to true when they are given
as arguments.
|
MutableMap<V,K> |
flipUniqueValues()
Return the MapIterable that is obtained by flipping the direction of this map and making the associations
from value to key.
|
V |
getIfAbsentPut(K key,
Function0<? extends V> function)
Get and return the value in the Map at the specified key.
|
V |
getIfAbsentPut(K key,
V value)
Get and return the value in the Map at the specified key.
|
<P> V |
getIfAbsentPutWith(K key,
Function<? super P,? extends V> function,
P parameter)
Get and return the value in the Map at the specified key.
|
V |
getIfAbsentPutWithKey(K key,
Function<? super K,? extends V> function)
Get and return the value in the Map at the specified key.
|
<V1> MutableMap<V1,V> |
groupByUniqueKey(Function<? super V,? extends V1> function)
For each element of the iterable, the function is evaluated and he results of these evaluations are collected
into a new map, where the transformed value is the key.
|
Iterator<V> |
iterator() |
RichIterable<K> |
keysView()
Returns an unmodifiable lazy iterable wrapped around the keySet for the map
|
RichIterable<Pair<K,V>> |
keyValuesView()
Returns an unmodifiable lazy iterable of key/value pairs wrapped around the entrySet for the map
|
V |
updateValue(K key,
Function0<? extends V> factory,
Function<? super V,? extends V> function)
Looks up the value associated with
key, applies the function to it, and replaces the value. |
<P> V |
updateValueWith(K key,
Function0<? extends V> factory,
Function2<? super V,? super P,? extends V> function,
P parameter)
Same as
MutableMapIterable.updateValue(Object, Function0, Function) with a Function2 and specified parameter which is
passed to the function. |
RichIterable<V> |
valuesView()
Returns an unmodifiable lazy iterable wrapped around the values for the map
