示例1: model
export default function model(serializedGraph$: Stream<string>,
speed$: Stream<ZapSpeed>): Stream<DiagramState | null> {
const object$ = serializedGraph$
.filter(str => str.length > 0)
.map(serializedObject => CircularJSON.parse(serializedObject));
const graphAndZap$ = object$
.map(object => {
const id: string = object.id || 'graph-0';
const zaps: Array<Zap> = object.zaps;
object.zaps = null;
const graph: dagre.graphlib.Graph = dagre.graphlib['json'].read(object);
return { graph, zaps, id };
});
const diagramState$ = xs.combine(graphAndZap$, speed$.startWith('normal'))
.map(([{id, graph, zaps}, speed]) => ({ id, graph, zaps, speed } as DiagramState));
const invalidState$ = serializedGraph$
.filter(str => str.length === 0)
.mapTo(null);
return xs.merge(diagramState$, invalidState$);
