new TaskHandlingService(_taskContentService: TaskContentService, _selectedCaseService?: SelectedCaseService): TaskHandlingService

- Defined in projects/netgrif-components-core/src/lib/task/services/task-handling-service.ts:15
Parameters
- _taskContentService: TaskContentService
  
  the service that holds the currently selected task, that is handled by the implementation of this class
- _selectedCaseService: SelectedCaseService = null
  
  an optional service, that holds the currently selected case. It should be injected with the @Optional() annotation, since it might not be always provided.
Returns TaskHandlingService

Properties

Protected _selectedCaseService

_selectedCaseService: SelectedCaseService = null

Protected _taskContentService

_taskContentService: TaskContentService

Accessors

Protected _safeTask

get _safeTask(): Task

- Defined in projects/netgrif-components-core/src/lib/task/services/task-handling-service.ts:31
Throws an error if the TaskContentService didn't have the Task object set yet.

Returns Task
the Task object held by TaskContentService.

Protected _task

get _task(): Task

- Defined in projects/netgrif-components-core/src/lib/task/services/task-handling-service.ts:22
Returns Task
the Task object held by TaskContentService or undefined if the Service currently holds no Task.

Methods

Protected isTaskPresent

isTaskPresent(): boolean

- Defined in projects/netgrif-components-core/src/lib/task/services/task-handling-service.ts:42
Returns boolean
true if a Task instance is set, false otherwise

Protected isTaskRelevant

isTaskRelevant(requestedTaskId: string): boolean

- Defined in projects/netgrif-components-core/src/lib/task/services/task-handling-service.ts:56
Checks whether the current state of the TaskContentService and optionally if the SelectedCaseService, is still relevant to the task that was requested.

This method is useful if you use UnlimitedTaskContentService, or a similar implementation. It is possible for the currently "selected" task to change in-between a backend request was sent and the response was received. In that case the response is no longer relevant and should be discarded, otherwise an illegal task state could be achieved on frontend.

Parameters
- requestedTaskId: string
  
  the stringId of the requested task
Returns boolean
true if the requested task is still relevant to the state of the frontend. Returns false otherwise.
