AddObjectAsync

AddObjectAsync is a method name used in many object-oriented and data-access layers to describe an asynchronous operation that adds a new object to a collection, repository, or data store. The method typically accepts the object to be added and may optionally accept a cancellation token. The return type is usually Task, often Task<T>, where T is the type of the added object or its key, or Task<bool> indicating success.

Semantics vary by implementation: some designs perform the insertion and immediately persist the change when the method completes, while others add to an in-memory context and require a separate save or commit step. The method often performs input validation, checks for duplicates, assigns identifiers if needed, and enforces business rules. It may throw exceptions for invalid state, constraint violations, or external errors, and can honor the cancellation token to terminate the operation prematurely.

Usage is commonly found in repository or service layers. Typical patterns include AddObjectAsync(entity, cancellationToken) returning the added entity with a generated ID, or returning the new ID. In ORM contexts, the equivalent operation might involve adding to a change tracker and invoking a separate SaveChangesAsync to persist the data.

Considerations when using AddObjectAsync include ensuring thread-safety, understanding the persistence semantics (whether the addition is persisted immediately or requires a separate commit), managing transactions, and handling exceptions gracefully. Performance considerations involve IO-bound operations and the potential for partial failures in distributed or multi-step workflows.
