You can pass either an array of\n * Observables, or put them directly as arguments. Passing an empty array will result\n * in Observable that completes immediately.\n *\n * `concat` will subscribe to first input Observable and emit all its values, without\n * changing or affecting them in any way. When that Observable completes, it will\n * subscribe to then next Observable passed and, again, emit its values. This will be\n * repeated, until the operator runs out of Observables. When last input Observable completes,\n * `concat` will complete as well. At any given moment only one Observable passed to operator\n * emits values. If you would like to emit values from passed Observables concurrently, check out\n * {@link merge} instead, especially with optional `concurrent` parameter. As a matter of fact,\n * `concat` is an equivalent of `merge` operator with `concurrent` parameter set to `1`.\n *\n * Note that if some input Observable never completes, `concat` will also never complete\n * and Observables following the one that did not complete will never be subscribed. On the other\n * hand, if some Observable simply completes immediately after it is subscribed, it will be\n * invisible for `concat`, which will just move on to the next Observable.\n *\n * If any Observable in chain errors, instead of passing control to the next Observable,\n * `concat` will error immediately as well. Observables that would be subscribed after\n * the one that emitted error, never will.\n *\n * If you pass to `concat` the same Observable many times, its stream of values\n * will be \"replayed\" on every subscription, which means you can repeat given Observable\n * as many times as you like. If passing the same Observable to `concat` 1000 times becomes tedious,\n * you can always use {@link repeat}.\n *\n * @example <caption>Concatenate a timer counting from 0 to 3 with a synchronous sequence from 1 to 10</caption>\n * var timer = Rx.Observable.interval(1000).take(4);\n * var sequence = Rx.Observable.range(1, 10);\n * var result = Rx.Observable.concat(timer, sequence);\n * result.subscribe(x => console.log(x));\n *\n * // results in:\n * // 0 -1000ms-> 1 -1000ms-> 2 -1000ms-> 3 -immediate-> 1 ... 10\n *\n *\n * @example <caption>Concatenate an array of 3 Observables</caption>\n * var timer1 = Rx.Observable.interval(1000).take(10);\n * var timer2 = Rx.Observable.interval(2000).take(6);\n * var timer3 = Rx.Observable.interval(500).take(10);\n * var result = Rx.Observable.concat([timer1, timer2, timer3]); // note that array is passed\n * result.subscribe(x => console.log(x));\n *\n * // results in the following:\n * // (Prints to console sequentially)\n * // -1000ms-> 0 -1000ms-> 1 -1000ms-> ... 9\n * // -2000ms-> 0 -2000ms-> 1 -2000ms-> ... 5\n * // -500ms-> 0 -500ms-> 1 -500ms-> ... 9\n *\n *\n * @example <caption>Concatenate the same Observable to repeat it</caption>\n * const timer = Rx.Observable.interval(1000).take(2);\n *\n * Rx.Observable.concat(timer, timer) // concating the same Observable!\n * .subscribe(\n * value => console.log(value),\n * err => {},\n * () => console.log('...and it is done!')\n * );\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 0 after 3s\n * // 1 after 4s\n * // \"...and it is done!\" also after 4s\n *\n * @see {@link concatAll}\n * @see {@link concatMap}\n * @see {@link concatMapTo}\n *\n * @param {ObservableInput} input1 An input Observable to concatenate with others.\n * @param {ObservableInput} input2 An input Observable to concatenate with others.\n * More than one input Observables may be given as argument.\n * @param {Scheduler} [scheduler=null] An optional IScheduler to schedule each\n * Observable subscription on.\n * @return {Observable} All values of each passed Observable merged into a\n * single Observable, in order, in serial fashion.\n * @static true\n * @name concat\n * @owner Observable\n */\nexport function concat<T, R>(...observables: Array<ObservableInput<any> | IScheduler>): Observable<R> {\n if (observables.length === 1 || (observables.length === 2 && isScheduler(observables[1]))) {\n return from(<any>observables[0]);\n }\n return concatAll()(of(...observables)) as Observable<R>;\n}\n"]}
