@AfterDestroy

function AfterDestroy(): PropertyDecorator;

A PropertyDecorator factory applied to a method — registers that method under the 'after-destroy' bucket on the entity's EntityMetadata.eventListeners:

class Customer {
  @AfterDestroy()
  logDeleted(): void {
    // ...
  }
}

Throws You can define a Column for only string properties if applied to a symbol-keyed property, and Property must be a function if the decorated property isn't a function.

As of this version of @sqb/connect, nothing in Repository or the create/update/delete command implementations reads eventListeners back or calls the registered functions — attaching @AfterDestroy() to a method registers it as metadata only; it does not, by itself, make that method run after repo.delete(...)/deleteMany(...) removes a row. See Lifecycle Hooks for the full explanation and workarounds.
