readonly dbReady: Observable<boolean>;

property dbReadySubject

protected dbReadySubject: any;

property inMemDbService

protected inMemDbService: InMemoryDbService;

property requestInfoUtils

protected requestInfoUtils: RequestInfoUtilities;

method addDelay

protected addDelay: (response: Observable<any>) => Observable<any>;

• Add configured delay to response observable unless delay === 0

method applyQuery

protected applyQuery: (collection: any[], query: Map<string, string[]>) => any[];

• Apply query/search parameters as a filter over the collection This impl only supports RegExp queries on string properties of the collection ANDs the conditions together

method bind

protected bind: <T extends Function>(methodName: string) => T | undefined;

method bodify

protected bodify: (data: any) => any;

  When the last segment of the apiBase path is "commands", the collectionName is the command.

  Example URLs: commands/resetdb (POST) // Reset the "database" to its original state commands/config (GET) // Return this service's config object commands/config (POST) // Update the config (e.g. the delay)

  Usage: http.post('commands/resetdb', undefined); http.get('commands/config'); http.post('commands/config', '{"delay":1000}');

method genIdDefault

protected genIdDefault: <T extends { id: any }>(
    collection: T[],
    collectionName: string
) => any;

  Parameter collection

  collection of items with id key property

  Parameter collectionName

  name of the collection

method get

    collection,
    collectionName,
    headers,
    id,
    query,
    url,
}: RequestInfo_2) => ResponseOptions;

method getJsonBody

protected abstract getJsonBody: (req: any) => any;

• Get JSON body from the request object

method getLocation

protected getLocation: (url: string) => UriInfo;

• Get location info from a url, even on server where document is not defined

method getPassThruBackend

protected getPassThruBackend: () => PassThruBackend;

• get or create the function that passes unhandled requests through to the "real" backend.

method getRequestInfoUtils

  Parameter req

  request object from the http call

method handleRequest

protected handleRequest: (req: RequestCore) => Observable<any>;

• Process Request and return an Observable of Http Response object in the manner of a RESTy web api.

  Expect URI pattern in the form :base/:collectionName/:id? Examples: // for store with a 'customers' collection GET api/customers // all customers GET api/customers/42 // the character with id=42 GET api/customers?name=^j // 'j' is a regex; returns customers whose name starts with 'j' or 'J' GET api/customers.json/42 // ignores the ".json"

  Also accepts direct commands to the service in which the last segment of the apiBase is the word "commands" Examples: POST commands/resetDb, GET/POST commands/config - get or (re)set the config

  HTTP overrides: If the injected inMemDbService defines an HTTP method (lowercase) The request is forwarded to that method as in inMemDbService.get(requestInfo) which must return either an Observable of the response type for this http library or null|undefined (which means "keep processing").

method handleRequest_

protected handleRequest_: (req: RequestCore) => Observable<any>;

method indexOf

protected indexOf: (collection: any[], id: number) => number;

method isCollectionIdNumeric

protected isCollectionIdNumeric: <T extends { id: any }>(
    collection: T[],
    collectionName: string
) => boolean;

• return true if can determine that the collection's item.id is a number This implementation can't tell if the collection is empty so it assumes NO

method parseId

protected parseId: (
    collection: any[],
    collectionName: string,
    id: string
) => any;

• Parse the id as a number. Return original value if not a number.

method parseRequestUrl

protected parseRequestUrl: (url: string) => ParsedRequestUrl;

• Parses the request URL into a ParsedRequestUrl object. Parsing depends upon certain values of config: apiBase, host, and urlRoot.

  Configuring the apiBase yields the most interesting changes to parseRequestUrl behavior: When apiBase=undefined and url='http://localhost/api/collection/42' {base: 'api/', collectionName: 'collection', id: '42', ...} When apiBase='some/api/root/' and url='http://localhost/some/api/root/collection' {base: 'some/api/root/', collectionName: 'collection', id: undefined, ...} When apiBase='/' and url='http://localhost/collection' {base: '/', collectionName: 'collection', id: undefined, ...}

  The actual api base segment values are ignored. Only the number of segments matters. The following api base strings are considered identical: 'a/b' ~ 'some/api/' ~ `two/segments'

  To replace this default method, assign your alternative to your InMemDbService['parseRequestUrl']

}: RequestInfo_2) => ResponseOptions;

protected resetDb: (reqInfo?: RequestInfo_2) => Observable<boolean>;

method forFeature

    dbCreator: Type<InMemoryDbService>,
    options?: InMemoryBackendConfigArgs
) => ModuleWithProviders<HttpClientInMemoryWebApiModule>;

• Enable and configure the in-memory web api in a lazy-loaded feature module. Same as forRoot. This is a feel-good method so you can follow the Angular style guide for lazy-loaded modules.

  Usually imported in the root application module. Can import in a lazy feature module too, which will shadow modules loaded earlier

  Note: If you use the FetchBackend, make sure forRoot is invoked after in the providers list

  Parameter dbCreator

  Class that creates seed data for in-memory database. Must implement InMemoryDbService.

  Parameter options

  Example 1

  HttpInMemoryWebApiModule.forRoot(dbCreator); HttpInMemoryWebApiModule.forRoot(dbCreator, {useValue: {delay:600}});

method createDb

abstract createDb: (
    reqInfo?: RequestInfo_2
) => {} | Observable<{}> | Promise<{}>;

• Creates an in-memory "database" hash whose keys are collection names and whose values are arrays of collection objects to return or update.

  returns Observable of the database because could have to create it asynchronously.

  This method must be safe to call repeatedly. Each time it should return a new object with new arrays containing new item objects. This condition allows the in-memory backend service to mutate the collections and their items without touching the original source data.

  The in-mem backend service calls this method without a value the first time. The service calls it with the RequestInfo when it receives a POST commands/resetDb request. Your InMemoryDbService can adjust its behavior accordingly.
