Aggregations

The AggregationsService handles aggregation-related operations: loading more items in a flat aggregation or opening a node in a tree aggregation.

note

Retrieving sorted aggregations based on a query name is provided by getAuthorizedFilters() in AppStore, not in this service.

Methods

loadMore()

Loads more items for a given aggregation.

loadMore(query: Partial<Query>, aggregation: Aggregation, audit?: AuditEvents): Observable<Aggregation>

Name	Type	Required	Description
query	Partial<Query>	✓	The current query parameters.
aggregation	Aggregation	✓	The aggregation for which to load more items.
audit	AuditEvents		Optional audit events to record.

Returns Observable<Aggregation> — emits the updated aggregation with additional items.

Example

example.component.ts

import { inject } from '@angular/core';
import { AggregationsService } from '@sinequa/atomic-angular';

const aggregationsService = inject(AggregationsService);

aggregationsService.loadMore(query, aggregation).subscribe(updated => {
  console.log(updated);
});

open()

Opens a node in a tree aggregation to reveal its children.

open(query: Partial<Query>, aggregation: TreeAggregation, item: TreeAggregationNode): Observable<TreeAggregation>

Name	Type	Required	Description
query	Partial<Query>	✓	The current query parameters.
aggregation	TreeAggregation	✓	The tree aggregation containing the node to open.
item	TreeAggregationNode	✓	The node to open.

Returns Observable<TreeAggregation> — emits the updated tree aggregation with the node opened.

Example

example.component.ts

import { inject } from '@angular/core';
import { AggregationsService } from '@sinequa/atomic-angular';

const aggregationsService = inject(AggregationsService);

aggregationsService.open(query, treeAggregation, node).subscribe(updated => {
  console.log(updated);
});
