Extends: MultiMapBase.Factory<Tp,UK,UV>

Methods

builder

Returns an empty builder instance for this type of collection and context.

Definition

example

HashMultiMapHashValue.builder<number, string>()    // => HashMultiMapHashValue.Builder<number, string>

Overrides

Factory.builder

createContext

Returns a new SortedMultiMapSortedValue context instance based on the given options.

Definition

createContext<K, V>(options?: {
    keyMapContext?: SortedMap.Context<K>;
    keyMapValuesContext?: SortedSet.Context<V>;
  }): SortedMultiMapSortedValue.Context<K, V>;

Type parameters

Name	Description
K
V

Parameters

Name	Type	Description
options	{     keyMapContext?: SortedMap.Context<K>;     keyMapValuesContext?: SortedSet.Context<V>;   }	(optional) an object containing the following properties: - keyMapContext: (optional) the map context to use for key to valueset mappings - keyMapValuesContext: (optional) the set context to use for value sets

defaultContext

Returns the default context for HashMultiMapHashValue.

Definition

defaultContext<UK, UV>(): SortedMultiMapSortedValue.Context<UK, UV>;

Type parameters

Name	Description
UK	the upper key type for which the context can create instances
UV	the upper value type for which the context can create instances

empty

Returns the (singleton) empty instance of this type and context with given key and value types.

Definition

empty<K extends UK, V extends UV>(): WithKeyValue<Tp, K, V>['normal'];

Type parameters

Name	Constraints	Description
K	UK
V	UV

example

HashMultiMapHashValue.empty<number, string>()    // => HashMultiMapHashValue<number, string>
HashMultiMapHashValue.empty<string, boolean>()   // => HashMultiMapHashValue<string, boolean>

Overrides

Factory.empty

from

Returns an immutable multimap of this type and context, containing the entries in the given source StreamSource.

Definitions

from<K extends UK, V extends UV>(...sources: ArrayNonEmpty<StreamSource.NonEmpty<readonly [K, V]>>): WithKeyValue<Tp, K, V>['nonEmpty'];

from<K extends UK, V extends UV>(...sources: ArrayNonEmpty<StreamSource<readonly [K, V]>>): WithKeyValue<Tp, K, V>['normal'];

Type parameters

Name	Constraints	Description
K	UK
V	UV

Parameters

Name	Type	Description
sources	ArrayNonEmpty<StreamSource.NonEmpty<readonly [K, V]>>	an array of StreamSource instances containing key-value entries

example

HashMultiMapHashValue.from([[1, 'a'], [2, 'b']])    // => HashMultiMapHashValue.NonEmpty<number, string>

Overrides

Factory.from

of

Returns an immutable multimap of this collection type and context, containing the given entries.

Definition

of<K extends UK, V extends UV>(...entries: ArrayNonEmpty<readonly [K, V]>): WithKeyValue<Tp, K, V>['nonEmpty'];

Type parameters

Name	Constraints	Description
K	UK
V	UV

Parameters

Name	Type	Description
entries	ArrayNonEmpty<readonly [K, V]>	a non-empty array of key-value entries

example

HashMultiMapHashValue.of([1, 'a'], [2, 'b'], [1, 'c'])    // => HashMap.NonEmpty<number, string>

Overrides

Factory.of

reducer

Returns a Reducer that adds received tuples to a MultiMap and returns the MultiMap as a result. When a source is given, the reducer will first create a MultiMap from the source, and then add tuples to it.

Definition

reducer<K extends UK, V extends UV>(source?: StreamSource<readonly [K, V]>): Reducer<readonly [K, V], WithKeyValue<Tp, K, V>['normal']>;

Type parameters

Name	Constraints	Description
K	UK
V	UV

Parameters

Name	Type	Description
source	StreamSource<readonly [K, V]>	(optional) an initial source of tuples to add to

example

const someSource: [number, string][] = [1, 'a'], [2, 'b'];
const result = Stream.of([1, 'c'], [3, 'a']).reduce(SortedMultiMap.reducer(someSource))
result.toArray()   // => [[1, 'a'], [1, 'c'], [2, 'b'], [3, 'a']]

note

uses a builder under the hood. If the given source is a BiMap in the same context, it will directly call .toBuilder().

Overrides

Factory.reducer
