The priority of the operation task. Omit this parameter or pass .unspecified to set the child task’s priority to the priority of the group.

operation

The operation to execute as part of the task group.

Return Value 戻り値

Discussion 解説

This method doesn’t throw an error, even if the child task does. このメソッドは、エラーをスローしません、たとえ子タスクがするとしても。 Instead, the corresponding call to ThrowingTaskGroup.next() rethrows that error.
