+/**
+ * A view for displaying a {@link Slice} which is a piece of app content and actions. SliceView is
+ * able to present slice content in a templated format outside of the associated app. The way this
+ * content is displayed depends on the structure of the slice, the hints associated with the
+ * content, and the mode that SliceView is configured for. The modes that SliceView supports are:
+ * <ul>
+ * <li><b>Shortcut</b>: A shortcut is presented as an icon and a text label representing the main
+ * content or action associated with the slice.</li>
+ * <li><b>Small</b>: The small format has a restricted height and can present a single
+ * {@link SliceItem} or a limited collection of items.</li>
+ * <li><b>Large</b>: The large format displays multiple small templates in a list, if scrolling is
+ * not enabled (see {@link #setScrollable(boolean)}) the view will show as many items as it can
+ * comfortably fit.</li>
+ * </ul>
+ * <p>
+ * When constructing a slice, the contents of it can be annotated with hints, these provide the OS
+ * with some information on how the content should be displayed. For example, text annotated with
+ * {@link Slice#HINT_TITLE} would be placed in the title position of a template. A slice annotated
+ * with {@link Slice#HINT_LIST} would present the child items of that slice in a list.
+ * <p>
+ * SliceView can be provided a slice via a uri {@link #setSlice(Uri)} in which case a content
+ * observer will be set for that uri and the view will update if there are any changes to the slice.
+ * To use this the app must have a special permission to bind to the slice (see
+ * {@link android.Manifest.permission#BIND_SLICE}).
+ * <p>
+ * Example usage:
+ *
+ * <pre class="prettyprint">
+ * SliceView v = new SliceView(getContext());
+ * v.setMode(desiredMode);
+ * v.setSlice(sliceUri);
+ * </pre>

+/**
+ * Implementation details:
+ * This binary auto generates .cpp files for incident and incidentd.
+ *
+ * When argument "incident" is specified, it generates incident_section.cpp file.
+ *
+ * When argument "incidentd" is specified, it generates section_list.cpp file.
+ *
+ * In section_list.cpp file, it generates a SECTION_LIST array and a PRIVACY_POLICY_LIST array.
+ * For SECTION_LIST, it generates Section.h classes only for proto fields with section option enabled.
+ * For PRIVACY_POLICY_LIST, it generates Privacy.h classes only for proto fields with privacy option enabled.
+ *
+ * For Privacy struct, it is possible to have self recursion definitions since protobuf is defining "classes"
+ * So the logic to handle it becomes very complicated when Privacy tag of a message contains a list of Privacies
+ * of its sub-messages. The code also handles multiple depth of self recursion fields.
+ *
+ * For example here is a one level self recursion message WindowManager:
+ * message WindowState {
+ *     string state = 1 [(privacy).dest = LOCAL];
+ *     int32  display_id = 2;
+ *     repeated WindowState child_windows = 3;
+ * }
+ *
+ * message WindowManager {
+ *     WindowState my_window = 1;
+ * }
+ *
+ * When generating Privacy options for WindowManager, this tool will generate cpp syntax source code:
+ *
+ * #include "section_list.h"
+ * ...
+ * Privacy WindowState_state { 1, 9, NULL, LOCAL, NULL }; // first two integers are values for field id and proto type.
+ * Privacy WindowState_child_windows { 3, 11, NULL, DEFAULT, NULL }; // reserved for WindowState_LIST
+ * Privacy* WindowState_MSG_[] = {
+ *     &WindowState_state,
+ *     // display id is default, nothing is generated.
+ *     &WindowState_child_windows,
+ *     NULL  // terminator of the array
+ * };
+ * Privacy WindowState_my_window { 1, 11, WindowState_my_window_LIST, DEFAULT, NULL };
+ *
+ * createList() {
+ *    ...
+ *    WindowState_child_windows.children = WindowState_my_window_LIST; // point to its own definition after the list is defined.
+ *    ...
+ * }
+ *
+ * const Privacy** PRIVACY_POLICY_LIST = createList();
+ * const int PRIVACY_POLICY_COUNT = 1;
+ */
+
+// The assignments will be called when constructs PRIVACY_POLICY_LIST, has to be global variable
+vector<string> gSelfRecursionAssignments;
