`destroy`

The destroy method should be called when this Indexes object is no longer used.

destroy(): void

This guarantees that all of the listeners that the object registered with the underlying Store are removed and it can be correctly garbage collected.

Example

This example creates a Store, adds an Indexes object with a definition (that registers a RowListener with the underlying Store), and then destroys it again, removing the listener.

const store = createStore().setTable('pets', {
  fido: {species: 'dog'},
  felix: {species: 'cat'},
  cujo: {species: 'dog'},
});

const indexes = createIndexes(store);
indexes.setIndexDefinition('bySpecies', 'pets', 'species');
console.log(store.getListenerStats().row);
// -> 1

indexes.destroy();

console.log(store.getListenerStats().row);
// -> 0
