RETAIN_CLASS_REFERENCE
public static final StackWalker.Option RETAIN_CLASS_REFERENCE
RetainsClassobject inStackFrames walked by thisStackWalker.A
StackWalkerconfigured with this option will supportStackWalker.getCallerClass()andStackFrame.getDeclaringClass().
-
SHOW_REFLECT_FRAMES
public static final StackWalker.Option SHOW_REFLECT_FRAMES
Shows all reflection frames.By default, reflection frames are hidden. A
StackWalkerconfigured with thisSHOW_REFLECT_FRAMESoption will show all reflection frames that includeMethod.invoke(java.lang.Object, java.lang.Object...)andConstructor.newInstance(Object...)and their reflection implementation classes.The
SHOW_HIDDEN_FRAMESoption 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 of
MethodandConstructor. Any utility methods that are equivalent to callingMethod.invokeorConstructor.newInstancesuch asClass.newInstanceare 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 to reflection frames. A
StackWalkerwith thisSHOW_HIDDEN_FRAMESoption will show all hidden frames (including reflection frames).

values
public static StackWalker.Option[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:for (StackWalker.Option c : StackWalker.Option.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static StackWalker.Option valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException- if this enum type has no constant with the specified nameNullPointerException- if the argument is null
