• RETAIN_CLASS_REFERENCE

  public static final StackWalker.Option RETAIN_CLASS_REFERENCE

  RetainsClass object inStackFrames walked by thisStackWalker.

  AStackWalker configured with this option will supportStackWalker.getCallerClass() andStackFrame.getDeclaringClass().

• DROP_METHOD_INFO

  public static final StackWalker.Option DROP_METHOD_INFO

• SHOW_REFLECT_FRAMES

  public static final StackWalker.Option SHOW_REFLECT_FRAMES

  Shows all reflection frames.

  By default, reflection frames are hidden. AStackWalker configured with thisSHOW_REFLECT_FRAMES option will show all reflection frames that includeMethod.invoke(java.lang.Object, java.lang.Object...) andConstructor.newInstance(Object...) and their reflection implementation classes.

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

  API Note:

  This option includes the stack frames representing the invocation ofMethod andConstructor. Any utility methods that are equivalent to callingMethod.invoke orConstructor.newInstance such asClass.newInstance are not filtered or controlled by any stack walking option.

• SHOW_HIDDEN_FRAMES

  public static final StackWalker.Option SHOW_HIDDEN_FRAMES

  Shows all hidden frames.

  A Java Virtual Machine implementation may hide implementation specific frames in addition toreflection frames. AStackWalker with thisSHOW_HIDDEN_FRAMES option will show all hidden frames (including reflection frames).
