示例1: requestAllFromServer
// This method will return an observable that gets todos from sever, we will simulate that with a delay
private requestAllFromServer() {
return Observable.return([
{text: "Todo 1"},
{text: "Todo 2"},
{text: "Todo 3"},
{text: "Todo 4"},
]).delay(1000);
}示例2: makeUpdates
export function makeUpdates (initialState: TcombUpdatesState, token: Token): Observable<TcombUpdatesState> {
UpdatesState(initialState)
let resolve = makeUpdatesResolver(token)
return $.return(initialState).expand(({offset}) => resolve(offset)
.combineLatest(
$.interval(500).take(1),
(updates: TcombUpdate[], _: any) => UpdatesState({
startDate: initialState.startDate,
offset: reduce(max('update_id'), 0, updates) + 1,
updates
})))
}示例3: constructor
constructor (name: string, frequency: number, action) {
var modifiedSinceInitValue = Date.now();
var polling_frequency = frequency;
var initial_state = {modifiedSince: modifiedSinceInitValue, itemArray : []}
function max(property) {
return function (acc, current) {
acc = current[property] > acc ? current[property] : acc;
}
}
return Observable.return(initial_state)
.expand (function(state){
return Rx.Observable.fromPromise(action(state.modifiedSince))
.toArray()
.combineLatest(Observable.interval(polling_frequency).take(1),
function (itemArray, _) {
return {
modifiedSince : itemArray.reduce(max('updatedAt'), modifiedSinceInitValue),
itemArray : itemArray
}
}
)
});
