示例1: readRequest
protected readRequest(state: State): Observable<HttpResponse<Object>> {
return this.getDataSource().pipe(
switchMap(dataSource => dataSource.read(this.getFilterOptions(state))),
map(data => this.parseDSResponse(data)),
catchError((error, retry) => _throw(this.getErrorResponse(error)))
);
}示例2: switchMap
switchMap((action: ActionStockMarketRetrieve) =>
this.service
.retrieveStock(action.payload.symbol)
.pipe(
map(stock => new ActionStockMarketRetrieveSuccess({ stock })),
catchError(error =>
of(new ActionStockMarketRetrieveError({ error }))
)
)示例3:
resolveFn: (catalog: CatalogService, state: StateService, loading: TdLoadingService) => {
loading.register(ConnectorComponent.LOADER);
return catalog.getConnector(state.transition.params().connectorId)
.pipe(finalize(() => loading.resolve(ConnectorComponent.LOADER)))
.pipe(catchError(() => {
return state.go("catalog.connectors")
}))
.toPromise();
}示例4: handleOperation
protected handleOperation(operation: (dataSource: DataSource) => void): Observable<any> {
return this.getDataSource().pipe(
switchMap(dataSource => {
operation(dataSource);
return dataSource.saveChanges();
}),
catchError((error, retry) => _throw(this.getErrorResponse(error)))
);
}示例5: switchMap
switchMap(action =>
this.service.retrieveStock(action.payload).pipe(
map(stock => ({
type: STOCK_MARKET_RETRIEVE_SUCCESS,
payload: stock
})),
