BaseOperation

open class BaseOperation<Success> : Operation

An operation that simplifies state flag handling and provides a method to finish a task delivering a result containing either a Success response or an Error response.

State behavior:

  • The operation, regardless of state, will always return isReady true.
  • An executing operation will return isExecuting true.
  • A finished operation will return isFinished true.
  • A cancelled operation will return isCancelled true.
