Methods

builder

Returns an empty builder instance.

Definition

Type parameters

Name	Constraints	Description
N	UN
V

example

ArrowValuedGraphHashed.builder<number, string>()    // => ArrowValuedGraphHashed.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<N extends UN, V>(): WithGraphValues<Tp, N, V>['normal'];

Type parameters

Name	Constraints	Description
N	UN
V

example

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

Overrides

Factory.empty

from

Returns an immutable valued Graph, containing the graph elements from each of the given sources.

Definitions

from<N extends UN, V>(...sources: ArrayNonEmpty<StreamSource.NonEmpty<ValuedGraphElement<N, V>>>): WithGraphValues<Tp, N, V>['nonEmpty'];

from<N extends UN, V>(...sources: ArrayNonEmpty<StreamSource<ValuedGraphElement<N, V>>>): WithGraphValues<Tp, N, V>['normal'];

Type parameters

Name	Constraints	Description
N	UN
V

Parameters

Name	Type	Description
sources	ArrayNonEmpty<StreamSource.NonEmpty<ValuedGraphElement<N, V>>>	an array of StreamSource instances containing graph elements to add

example

ArrowValuedGraphHashed.from([[1], [2]], [[3, 4, 'c']])  // => ArrowValuedGraphHashed.NonEmpty<number, string>

Overrides

Factory.from

of

Returns an immutable valued Graph instance containing the graph elements from the given graphElements.

Definition

of<N extends UN, V>(...graphElements: ArrayNonEmpty<ValuedGraphElement<N, V>>): WithGraphValues<Tp, N, V>['nonEmpty'];

Type parameters

Name	Constraints	Description
N	UN
V

Parameters

Name	Type	Description
graphElements	ArrayNonEmpty<ValuedGraphElement<N, V>>	a non-empty array of graph elements that are either a single tuple containing a node, or a triplet containing two connection nodes and the connection value.

example

ArrowValuedGraphHashed.of([1], [2], [3, 4, 'a']) // => ArrowValuedGraphHashed.NonEmpty<number, string>

Overrides

Factory.of

reducer

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

Definition

reducer<N extends UN, V>(source?: StreamSource.NonEmpty<ValuedGraphElement<N, V>>): Reducer<ValuedGraphElement<N, V>, WithGraphValues<Tp, N, V>['normal']>;

Type parameters

Name	Constraints	Description
N	UN
V

Parameters

Name	Type	Description
source	StreamSource.NonEmpty<ValuedGraphElement<N, V>>	(optional) an initial source of graph elements to add to

example

const someSource: ValuedGraphElement<number, string>[] = [[1, 2, 'a'], [3], [5]];
const result = Stream.of([1, 3, 'b'], [4, 3, 'c']).reduce(ArrowGraphSorted.reducer(someSource))
result.toArray()   // => [[1, 2, 'a'], [1, 3, 'b'], [4, 3, 'c'], [5]]

note

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

Overrides

Factory.reducer
