/**
 | 
						|
 * Performs HTTP requests.
 | 
						|
 * This service is available as an injectable class, with methods to perform HTTP requests.
 | 
						|
 * Each request method has multiple signatures, and the return type varies based on
 | 
						|
 * the signature that is called (mainly the values of `observe` and `responseType`).
 | 
						|
 *
 | 
						|
 * Note that the `responseType` *options* value is a String that identifies the
 | 
						|
 * single data type of the response.
 | 
						|
 * A single overload version of the method handles each response type.
 | 
						|
 * The value of `responseType` cannot be a union, as the combined signature could imply.
 | 
						|
 | 
						|
 *
 | 
						|
 * @usageNotes
 | 
						|
 * Sample HTTP requests for the [Tour of Heroes](/tutorial/tour-of-heroes/toh-pt0) application.
 | 
						|
 *
 | 
						|
 * ### HTTP Request Example
 | 
						|
 *
 | 
						|
 * ```
 | 
						|
 *  // GET heroes whose name contains search term
 | 
						|
 * searchHeroes(term: string): observable<Hero[]>{
 | 
						|
 *
 | 
						|
 *  const params = new HttpParams({fromString: 'name=term'});
 | 
						|
 *    return this.httpClient.request('GET', this.heroesUrl, {responseType:'json', params});
 | 
						|
 * }
 | 
						|
 * ```
 | 
						|
 *
 | 
						|
 * Alternatively, the parameter string can be used without invoking HttpParams
 | 
						|
 * by directly joining to the URL.
 | 
						|
 * ```
 | 
						|
 * this.httpClient.request('GET', this.heroesUrl + '?' + 'name=term', {responseType:'json'});
 | 
						|
 * ```
 | 
						|
 *
 | 
						|
 *
 | 
						|
 * ### JSONP Example
 | 
						|
 * ```
 | 
						|
 * requestJsonp(url, callback = 'callback') {
 | 
						|
 *  return this.httpClient.jsonp(this.heroesURL, callback);
 | 
						|
 * }
 | 
						|
 * ```
 | 
						|
 *
 | 
						|
 * ### PATCH Example
 | 
						|
 * ```
 | 
						|
 * // PATCH one of the heroes' name
 | 
						|
 * patchHero (id: number, heroName: string): Observable<{}> {
 | 
						|
 * const url = `${this.heroesUrl}/${id}`;   // PATCH api/heroes/42
 | 
						|
 *  return this.httpClient.patch(url, {name: heroName}, httpOptions)
 | 
						|
 *    .pipe(catchError(this.handleError('patchHero')));
 | 
						|
 * }
