  • Returns Observable<FilterProcessRepresentationModel> - The filter just added
• callApiProcessFilters(appId?: number): Promise<any>
  Calls getUserProcessInstanceFilters from the Alfresco JS API.
  • appId: number - (Optional) ID of the target app
  • Returns Promise<any> - List of filter details
• createDefaultFilters(appId: number): Observable<FilterProcessRepresentationModel[]>
  Creates and returns the default filters for an app.
  • appId: number - ID of the target app
  • Returns Observable<FilterProcessRepresentationModel[]> - Default filters just created
• getProcessFilterById(filterId: number, appId?: number): Observable<FilterProcessRepresentationModel>
  Retrieves the process filter by ID.
  • filterId: number - ID of the filter
  • appId: number - (Optional) ID of the target app
  • Returns Observable<FilterProcessRepresentationModel> - Details of the filter
• getProcessFilterByName(filterName: string, appId?: number): Observable<FilterProcessRepresentationModel>
  Retrieves the process filter by name.
  • filterName: string - Name of the filter
  • appId: number - (Optional) ID of the target app
  • Returns Observable<FilterProcessRepresentationModel> - Details of the filter
• getProcessFilters(appId: number): Observable<FilterProcessRepresentationModel[]>
  Gets all filters defined for a Process App.
  • appId: number - ID of the target app
  • Returns Observable<FilterProcessRepresentationModel[]> - Array of filter details
• getRunningFilterInstance(appId: number): FilterProcessRepresentationModel

Details

The methods of this service generally return an instance of FilterProcessRepresentationModel or an array of instances. For example, you could use getProcessFilters as follows:

const processAppId = 2;
this.processFilterService.getProcessFilters(processAppId)
  .subscribe( (filters: FilterProcessRepresentationModel[]) => {
  console.log('filters: ', filters);
}, error => {
  console.log('Error: ', error);
});

The response is an array of FilterProcessRepresentationModel objects:

    filters:  
        0: {id: 15, appId: 2, name: "Running", recent: true, icon: "glyphicon-random", …}
        1: {id: 14, appId: 2, name: "Completed", recent: false, icon: "glyphicon-ok-sign", …}
        2: {id: 13, appId: 2, name: "All", recent: false, icon: "glyphicon-th", …}
        3: {id: 3003, appId: 2, name: "Running", recent: false, icon: "glyphicon-random", …}
        4: {id: 3004, appId: 2, name: "Completed", recent: false, icon: "glyphicon-ok-sign", …}
        5: {id: 3005, appId: 2, name: "All", recent: false, icon: "glyphicon-th", …}

You can use the returned filters to get matching process instances for the process app with ID 2, such as 'Running', 'Completed', 'All', etc.
