/**
|

* Launches an asynchronous execution on a prepared model.
|
|
*
|
|
* The execution is performed asynchronously with respect to the caller.
|
|
* execute_1_3 must verify the inputs to the function are correct. If there is
|
|
* an error, execute_1_3 must immediately invoke the callback with the
|
|
* appropriate ErrorStatus value, then return with the same ErrorStatus. If
|
|
* the inputs to the function are valid and there is no error, execute_1_3 must
|
|
* launch an asynchronous task to perform the execution in the background,
|
|
* and immediately return with ErrorStatus::NONE. If the asynchronous task
|
|
* fails to launch, execute_1_3 must immediately invoke the callback with
|
|
* ErrorStatus::GENERAL_FAILURE, then return with
|
|
* ErrorStatus::GENERAL_FAILURE.
|
|
*
|
|
* When the asynchronous task has finished its execution, it must
|
|
* immediately invoke the callback object provided as an input to the
|
|
* execute_1_3 function. This callback must be provided with the ErrorStatus of
|
|
* the execution.
|
|
*
|
|
* If the launch is successful, the caller must not change the content of
|
|
* any data object referenced by 'request' (described by the
|
|
* {@link @1.0::DataLocation} of a {@link @1.0::RequestArgument}) until the
|
|
* asynchronous task has invoked the callback object. The asynchronous task
|
|
* must not change the content of any of the data objects corresponding to
|
|
* 'request' inputs.
|
|
*
|
|
* If the prepared model was prepared from a model wherein all tensor
|
|
* operands have fully specified dimensions, and the inputs to the function
|
|
* are valid, then:
|
|
* - the execution should launch successfully (ErrorStatus::NONE): There
|
|
* must be no failure unless the device itself is in a bad state.
|
|
* - if at execution time every operation's input operands have legal
|
|
* values, the execution should complete successfully (ErrorStatus::NONE):
|
|
* There must be no failure unless the device itself is in a bad state.
|
|
*
|
|
* Any number of calls to the execute, execute_1_2, execute_1_3, and executeSynchronously
|
|
* functions, in any combination, may be made concurrently, even on the same
|
|
* IPreparedModel object.
|
|
*
|
|
* @param request The input and output information on which the prepared
|
|
* model is to be executed.
|
|
* @param measure Specifies whether or not to measure duration of the execution.
|
|
* The duration runs from the time the driver sees the call
|
|
* to the execute_1_3 function to the time the driver invokes
|
|
* the callback.
|
|
* @param callback A callback object used to return the error status of
|
|
* the execution. The callback object's notify function must
|
|
* be called exactly once, even if the execution was
|
|
* unsuccessful.
|
|
* @return status Error status of the call, must be:
|
|
* - NONE if task is successfully launched
|
|
* - DEVICE_UNAVAILABLE if driver is offline or busy
|
|
* - GENERAL_FAILURE if there is an unspecified error
|
|
* - OUTPUT_INSUFFICIENT_SIZE if provided output buffer is
|
|
* not large enough to store the resultant values
|
|
* - INVALID_ARGUMENT if one of the input arguments is
|
|
* invalid
