IPreparedModelCallback

interface IPreparedModelCallback

IPreparedModelCallback must be used to return a prepared model produced by an asynchronous task launched from IDevice::prepareModel.

Methods

notify

oneway notify (ErrorStatus status, IPreparedModel preparedModel)

notify must be invoked immediately after the asynchronous task holding this callback has finished preparing the model.If the model was successfully prepared, notify must be invoked with ErrorStatus::NONE and the prepared model.If the model was not able to be successfully prepared, notify must be invoked with the appropriate ErrorStatus and nullptr as the IPreparedModel.If the asynchronous task holding this callback fails to launch or if the model provided to IDevice::prepareModel is invalid, notify must be invoked with the appropriate error as well as nullptr for the IPreparedModel.

status
Error status returned from the asynchronous model preparation task;must be:- NONE if the asynchronous task successfully prepared the model - DEVICE_UNAVAILABLE if driver is offline or busy - GENERAL_FAILURE if the asynchronous task resulted in an unspecified error - INVALID_ARGUMENT if one of the input arguments to prepareModel is invalid
preparedModel
A model that has been asynchronously prepared for execution.If the model was unable to be prepared due to an error, nullptr must be passed in place of the IPreparedModel object.
