+ * 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.

+// 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.
