Method AsyncResult():signalError()

Signals an error condition with an error object.

:signalError( <oError> ) --> self

The error object indicating the reason for failure.

This method returns self.

This method is called by the producer of the AsyncResult to indicate that the asynchronous operation has failed. It transitions the AsyncResult from the "waiting" state to the "error" state and stores the provided error object.

If codeblocks have been registered through :catch() or :finally(), they will be executed when this method is called.

This method has no effect if the AsyncResult is not in the "waiting" state.
