Added in API level 34
enum val SHOW_REFLECT_FRAMES : StackWalker.Option

Shows all reflection frames.

By default, reflection frames are hidden. A StackWalker configured with this SHOW_REFLECT_FRAMES option will show all reflection frames that include java.lang.reflect.Method#invoke and java.lang.reflect.Constructor#newInstance(Object...) and their reflection implementation classes.

The SHOW_HIDDEN_FRAMES option can also be used to show all reflection frames and it will also show other hidden frames that are implementation-specific.
