Rx.Observable.mergeDelayError(...args)

Flattens an Observable that emits Observables into one Observable, in a way that allows an Observer to receive all successfully emitted items from all of the source Observables without being interrupted by an error notification from one of them.

This behaves like Observable.prototype.mergeAll except that if any of the merged Observables notify of an error via the Observer's onError, mergeDelayError will refrain from propagating that error notification until all of the merged Observables have finished emitting items.

Arguments

1. args (Array|arguments): Arguments or an array of Observable sequences to merge.

Returns

(Observable): An Observable that emits all of the items emitted by the Observables emitted by the Observable

Example

var source1 = Rx.Observable.of(1,2,3);
var source2 = Rx.Observable.throwError(new Error('woops'));
var source3 = Rx.Observable.of(4,5,6);

var source = Rx.Observable.mergeDelayError(source1, source2, source3);

var subscription = source.subscribe(
  function (x) {
    console.log('Next: %s', x);
  },
  function (err) {
    console.log('Error: %s', err);
  },
  function () {
    console.log('Completed');
  });
