+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+ * IBurst represents a burst execution object.
+ *
+ * Burst executions are a sequence of executions of the same prepared model that occur in rapid
+ * succession, such as frames of a camera capture or successive audio samples. A burst object is
+ * used to control a set of burst executions, and to preserve resources between executions, enabling
+ * executions to have lower overhead. Burst objects enable some optimizations:
+ * (1) A burst object is created before a sequence of executions, and freed when the sequence has
+ *     ended. Because of this, the lifetime of the burst object hints to a driver how long it should
+ *     remain in a high performance state.
+ * (2) A burst object can preserve resources between executions. For example, a driver can map a
+ *     memory object on the first execution and cache the mapping in the burst object for reuse in
+ *     subsequent executions. Any cached resource can be released when the burst object is destroyed
+ *     or when the NNAPI runtime notifies the burst object that the resource is no longer required.
+ * (3) A burst object may be used for at most one execution at a time. This enables any transient
+ *     execution resources such as intermediate tensors to be allocated once when the burst object
+ *     is created and freed when the burst object is destroyed.

+     * Performs a synchronous execution on a burst object.

+     * The execution is performed synchronously with respect to the caller. executeSynchronously
+     * must verify the inputs to the function are correct, and the usages of memory pools allocated
+     * by IDevice::allocate are valid. If there is an error, executeSynchronously must immediately
+     * return a service specific exception with the appropriate ErrorStatus value. If the inputs to
+     * the function are valid and there is no error, executeSynchronously must perform the
+     * execution, and must not return until the execution is complete.
+     *
+     * The caller must not change the content of any data object referenced by 'request' (described
+     * by the {@link DataLocation} of a {@link RequestArgument}) until executeSynchronously returns.
+     * executeSynchronously must not change the content of any of the data objects corresponding to
+     * 'request' inputs.
+     *
+     * If the burst object was configured from a prepared model wherein all tensor operands have
+     * fully specified dimensions, and the inputs to the function are valid, and at execution time
+     * every operation's input operands have legal values, then the execution should complete
+     * successfully: there must be no failure unless the device itself is in a bad state.
+     *
+     * executeSynchronously may be called with an optional deadline. If the execution is not able to
+     * be completed before the provided deadline, the execution may be aborted, and either
+     * {@link ErrorStatus::MISSED_DEADLINE_TRANSIENT} or {@link
+     * ErrorStatus::MISSED_DEADLINE_PERSISTENT} may be returned. The error due to an abort must be
+     * sent the same way as other errors, described above.
+     *
+     * Only a single execution on a given burst object may be active at any time.
+     *
+     * @param request The input and output information on which the prepared model is to be
+     *                executed.

+     *                               identifier token corresponds to an element of request.pools. A
+     *                               value of -1 indicates no identity.
+     * @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 executeSynchronously
+     *                function to the time the driver returns from the function.
+     * @param deadline The time by which the execution is expected to complete. The time is measured
+     *                 in nanoseconds since epoch of the steady clock (as from
+     *                 std::chrono::steady_clock). If the execution cannot be finished by the
+     *                 deadline, the execution may be aborted. Passing -1 means the deadline is
+     *                 omitted. Other negative values are invalid.
+     * @param loopTimeoutDuration The maximum amount of time in nanoseconds that should be spent
+     *                            executing a {@link OperationType::WHILE} operation. If a loop
+     *                            condition model does not output false within this duration, the
+     *                            execution must be aborted. If -1 is provided, the maximum amount
+     *                            of time is {@link DEFAULT_LOOP_TIMEOUT_DURATION_NS}. Other

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.
