Class DeleteMutator<TFields, TID, TViewerContext, TEntity, TPrivacyPolicy, TSelectedFields>

Private Readonly entity

Private deleteInTransactionAsync

• deleteInTransactionAsync(processedEntityIdentifiersFromTransitiveDeletions, skipDatabaseDeletion, cascadingDeleteCause): Promise<Result<void>>

• Parameters

  • processedEntityIdentifiersFromTransitiveDeletions: Set<string>

  • skipDatabaseDeletion: boolean

  • cascadingDeleteCause: null | EntityCascadingDeletionInfo

  Returns Promise<Result<void>>

Private deleteInternalAsync

• deleteInternalAsync(queryContext, processedEntityIdentifiersFromTransitiveDeletions, skipDatabaseDeletion, cascadingDeleteCause): Promise<Result<void>>

• Parameters

  • queryContext: EntityTransactionalQueryContext

  • processedEntityIdentifiersFromTransitiveDeletions: Set<string>

  • skipDatabaseDeletion: boolean

  • cascadingDeleteCause: null | EntityCascadingDeletionInfo

  Returns Promise<Result<void>>

Private processEntityDeletionForInboundEdgesAsync

• processEntityDeletionForInboundEdgesAsync(entity, queryContext, processedEntityIdentifiers, cascadingDeleteCause): Promise<void>

• Finds all entities referencing the specified entity and either deletes them, nullifies their references to the specified entity, or invalidates the cache depending on the OnDeleteBehavior of the field referencing the specified entity.

  Parameters

  • entity: TEntity

    entity to find all references to

  • queryContext: EntityTransactionalQueryContext

  • processedEntityIdentifiers: Set<string>

  • cascadingDeleteCause: null | EntityCascadingDeletionInfo

  Returns Promise<void>

  Remarks

  This works by doing reverse fan-out queries:

  1. Load all entity configurations of entity types that reference this type of entity
  2. For each entity configuration, find all fields that contain edges to this type of entity
  3. For each edge field, load all entities with an edge from target entity to this entity via that field
  4. Perform desired OnDeleteBehavior for entities
