    linkConnectionsContext?: HashMap.Context<UN>;
  }): ArrowValuedGraphHashed.Context<UN>;

Type parameters

Name	Description

defaultContext

Returns the default context for this type of graph.

Definition

defaultContext<UN>(): ArrowValuedGraphHashed.Context<UN>;

Type parameters

Name	Description
UN	the upper node type that the context should accept

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
