Details

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

const processAppId = 2;
this.taskFilterService.getTaskListFilters(processAppId).subscribe( (filters: FilterRepresentationModel[]) => {
  console.log('Task filters: ', filters);
}, error => {
  console.log('Error: ', error);
});

The response is an array of FilterRepresentationModel objects:

filters:  
    0: {id: 10, appId: 2, name: "Involved Tasks", recent: true, icon: "glyphicon-align-left", …}
    1: {id: 9, appId: 2, name: "My Tasks", recent: false, icon: "glyphicon-inbox", …}
    2: {id: 11, appId: 2, name: "Queued Tasks", recent: false, icon: "glyphicon-record", …}
    3: {id: 12, appId: 2, name: "Completed Tasks", recent: false, icon: "glyphicon-ok-sign", …}
    4: {id: 4004, appId: 2, name: "Completed Tasks", recent: false, icon: "glyphicon-ok-sign", …}
    5: {id: 4005, appId: 2, name: "My Tasks", recent: false, icon: "glyphicon-inbox", …}
    6: {id: 4006, appId: 2, name: "Queued Tasks", recent: false, icon: "glyphicon-record", …}
    7: {id: 4007, appId: 2, name: "Involved Tasks", recent: false, icon: "glyphicon-align-left", …}

These filters can now be used to get matching task instances for the process app with ID 2, such as 'Involved Tasks', 'My Tasks', 'Queued Tasks', and 'Completed Tasks'.
