namespace ArrowGraphHashed
An type-invariant immutable valued arrow (directed) graph. The connections are internally maintained using hashed collections See the Graph documentation and the ArrowGraphHashed API documentation
Companion interface: ArrowGraphHashed<N>
Interfaces
| Name | Description |
|---|---|
ArrowGraphHashed.Builder<N> | A mutable ArrowGraphHashed builder used to efficiently create new immutable instances. See the Graph documentation and the ArrowGraphHashed.Builder API documentation |
ArrowGraphHashed.Context<UN> | The ArrowGraphHashed's Context instance that serves as a factory for all related immutable instances and builders. |
ArrowGraphHashed.NonEmpty<N> | A non-empty type-invariant immutable valued arrow (directed) graph. The connections are internally maintained using hashed collections See the Graph documentation and the ArrowGraphHashed API documentation |
ArrowGraphHashed.Types | Utility interface that provides higher-kinded types for this collection. |

Overrides
reducer
Returns a Reducer that adds received graph elements to a Graph and returns the Graph 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.
reducerReducer that adds received graph elements to a Graph and returns the Graph 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>(source?: StreamSource.NonEmpty<GraphElement<N>>): Reducer<GraphElement<N>, WithGraphValues<Tp, N, unknown>['normal']>;
Type parameters
| Name | Constraints | Description |
|---|---|---|
| N | UN |
Parameters
| Name | Type | Description |
|---|---|---|
source | StreamSource.NonEmpty<GraphElement<N>> | (optional) an initial source of graph elements to add to |
const someSource: GraphElement<number>[] = [[1, 2], [3], [5]];
const result = Stream.of([1, 3], [4, 3]).reduce(ArrowGraphSorted.reducer(someSource))
result.toArray() // => [[1, 2], [1, 3], [4, 3], [5]]
uses a builder under the hood. If the given source is a Graph in the same context, it will directly call .toBuilder().
