class a2a.server.tasks.copying_task_store.CopyingTaskStoreAdapter(underlying_store: TaskStore)

Bases: TaskStore

An adapter that ensures deep copies of tasks are passed to and returned from the underlying TaskStore.

This prevents accidental shared mutable state bugs where code modifies a Task object retrieved from the store without explicitly saving it, which hides missing save calls.

async delete(task_id: str, context: ServerCallContext) → None

Deletes a task from the underlying store.

async get(task_id: str, context: ServerCallContext) → Task | None

Retrieves a task from the underlying store and returns a copy.

async list(params: ListTasksRequest, context: ServerCallContext) → ListTasksResponse

Retrieves a list of tasks from the underlying store and returns a copy.

async save(task: Task, context: ServerCallContext) → None

Saves a copy of the task to the underlying store.
