interface HashBiMultiMap.Context<UK,UV>

The HashBiMultiMap's Context instance that serves as a factory for all related immutable instances and builders.

Extends: BiMultiMapBase.Context<UK,UV,Tp>

Type parameters

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

Methods

builder

Returns an empty BiMultiMap builder instance.

Definition

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

Type parameters

Name	Constraints	Description
K	UK
V	UV

example

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

Overrides

Factory.builder

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

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

Overrides

Factory.empty

from

Returns an immutable BiMultiMap, containing the entries in the given sources StreamSource instances.

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 contaning key-value entries

example

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

Overrides

Factory.from

of

Returns an immutable BiMultiMap, 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

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

Overrides

Factory.of

reducer

Returns a Reducer that adds received tuples to a BiMultiMap and returns the BiMultiMap as a result. When a source is given, the reducer will first create a BiMultiMap 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 = BiMultiMap.of([1, 'a'], [2, 'b']);
const result = Stream.of([1, 'c'], [3, 'a']).reduce(BiMultiMap.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 BiMultiMap in the same context, it will directly call .toBuilder().

Overrides

Factory.reducer
