BaseListComponent

BaseListComponent

This is a base class which implements the logic required to fetch and manipulate a list of data from a query which returns a PaginatedList type.

It is normally used in combination with the DataTable2Component.

Signature
class BaseListComponent<ResultType, ItemType, VariableType extends Record<string, any> = any> implements OnInit, OnDestroy {

selectionManager = new SelectionManager<any>({
multiSelect: true,
itemsAreEqual: (a, b) => a.id === b.id,
additiveMode: true,
});
result$: Observable<ResultType>;
items$: Observable<ItemType[]>;
totalItems$: Observable<number>;
itemsPerPage$: Observable<number>;
currentPage$: Observable<number>;
protected destroy$ = new Subject<void>();
protected refresh$ = new BehaviorSubject<undefined>(undefined);
