PendingResult<S>
createFailedResult
(Status status)
Creates a failed result with the given Status
. In the event of an error during
onSuccess(R)
, call this method and return the failed result.
Note: the PendingResult
generated by this method must be returned directly from
onSuccess(R)
. It is an error to call any methods on this PendingResult.
public
Status
onFailure
(Status status)
Called when the PendingResult to be transformed returns a failure. Default implementation
simply propagates the failure, but subclasses may override for custom failure handling. This
method is called on the main thread, unless overridden by
setHandler(Handler)
.
Parameters |
status |
Status :
The status of the failure. |
Returns |
Status |
The status of the result of the transformation. Must not be success or null.

PendingResult<S>
onSuccess
(R result)
Transforms the result of a successful API call. This method is called on a background thread
and should not access UI elements.
Parameters |
result |
R :
The successful result to be transformed. Never null. If this result is
Releasable it will be automatically released after this transform is
applied; it is not necessary to release the result inside onSuccess. It is an
error to set callbacks on this result. Any callbacks set on this result will
be overridden and will not be called. |
Returns |
PendingResult<S> |
The result of the transformation. Normally the result of another API call. To
shortcut execution and directly yield a failure, return either:
