+/**
+ * Provides a central definition of debug SystemUI's SystemProperties flags, and their defaults.
+ *
+ * The main feature of this class is that it encodes a system-wide default for each flag which can
+ *  be updated by engineers with a single-line CL.
+ *
+ * NOTE: Because flag values returned by this class are not cached, it is important that developers
+ *  understand the intricacies of changing values and how that applies to their own code.
+ *  Generally, the best practice is to set the property, and then restart the device so that any
+ *  processes with stale state can be updated.  However, if your code has no state derived from the
+ *  flag value and queries it any time behavior is relevant, then it may be safe to change the flag
+ *  and not immediately reboot.
+ *
+ * To enable flags in debuggable builds, use the following commands:
+ *
+ * $ adb shell setprop persist.sysui.whatever_the_flag true
+ * $ adb reboot
+ *
+ * @hide
