[ https://issues.jboss.org/browse/SEAMCATCH-4?page=com.atlassian.jira.plugi... ] Dan Allen commented on SEAMCATCH-4: ----------------------------------- I played around with some ideas and we may even be able to use this for the exception mapping as well. Here are some prototype APIs. /** * A filter for processing the stack frames of a single exception (type parameter allows us to focus on a specific exception type) */ public interface ExceptionStackFrameFilter<T extends Throwable> { public StackFrameFilterResult process(StackFrame frame); } public interface StackFrame { StackElement getStackElement(); StackTraceElement getStackTraceElement(); void mark(String tag); StackFrame getMarkedFrame(String tag); boolean isMarkSet(String tag); void clearMark(String tag); void setStackTraceElement(StackTraceElement element); IterationStatus getIterationStatus(); } public enum StackFrameFilterResult { /** * Include this frame */ INCLUDE, /** * Drop this frame */ DROP, /** * Include this frame, but skip any remaining frames in this cause */ DROP_REMAINING, /** * Drop this frame and any remaining frames in this cause */ BREAK, /** * Stops processing any remaining frames or causes */ TERMINATE, /** * Include this frame, then stop processing any remaining frames or causes */ TERMINATE_AFTER } /** * A filter for processing the chained exceptions (i.e., the causes) */ public interface ExceptionStackFilter { public StackFilterResult process(StackElement element); } public interface StackElement { Throwable getThrowable(); void setThrowable(Throwable throwable); IterationStatus getIterationStatus(); } public enum StackFilterResult { /** * Include this throwable */ INCLUDE, /** * Drop this throwable, go to next in chain (if any) */ DROP, /** * Drop any remaining throwables in the chain */ DROP_REMAINING, /** * Drop throwable and any remaining in the chain */ TERMINATE } -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
