Rx.Observable.generate(initialState, condition, iterate, resultSelector, [scheduler])
Generates an observable sequence in a manner similar to a for loop, using an optional scheduler to enumerate the values.
Arguments
initialState
(Any
): Initial state.condition
(Function
): Condition to terminate generation (upon returning false).iterate
(Function
): Iteration step function.resultSelector
(Function
): Selector function for results produced in the sequence.[scheduler=Rx.Scheduler.currentThread]
(Scheduler
): Scheduler on which to run the generator loop. If not provided, defaults to Scheduler.currentThread.
Returns
(Observable
): The generated sequence.
Example
var source = Rx.Observable.generate(
0,
function (x) { return x < 3; },
function (x) { return x + 1; },
function (x) { return x; }
);
var subscription = source.subscribe(
function (x) {
console.log('Next: ' + x);
},
function (err) {
console.log('Error: ' + err);
},
function () {
console.log('Completed');
});
// => Next: 0
// => Next: 1
// => Next: 2
