Field Detail

• public static final String STACK_LOG_NAME

  The logger name for sanitized stack traces.

Method Detail

• public static void addClassTest(Closure test)

  Adds a groovy.lang.Closure to test whether the stack trace element should be added or not.

  The groovy.lang.Closure will be given the class name as parameter. the return value decides if the element will be added or not.

  • true - trace element will be added to the trace
  • false - trace element will not be added to the trace
  • null - continue with next test
  Groovy truth will be used to determine true and false, null is excluded from defaulting to false here. If all tests have been executed and all of them skipped, then the groovy standard filtering will take place.

  Parameters:

  test - the testing groovy.lang.Closure

• public static Throwable deepSanitize(Throwable t)

  Sanitize the exception and ALL nested causes

  This will MODIFY the stacktrace of the exception instance and all its causes irreversibly

  Parameters:

  t - a throwable

  Returns:

  The root cause exception instances, with stack trace modified to filter out groovy runtime classes

• public static Throwable extractRootCause(Throwable t)

  Extracts the root cause of the exception, no matter how nested it is

  Parameters:

  t - a Throwable

  Returns:

  The deepest cause of the exception that can be found

• public static boolean isApplicationClass(String className)

  Determines whether the given class name is an application class (not a Groovy runtime class). First checks any registered test closures, then checks against known Groovy packages.

  Parameters:

  className - the fully qualified class name to check

  Returns:

  true if the class is an application class, false if it's a Groovy runtime class

• public static void printSanitizedStackTrace(Throwable t, PrintWriter p)

  Prints the sanitized stack trace of the exception to the given writer. Removes apparently groovy-internal trace entries.

  Parameters:

  t - the Throwable whose stack trace to print

  p - the PrintWriter to print to

• public static void printSanitizedStackTrace(Throwable t)

  Prints the sanitized stack trace of the exception to standard error. Removes apparently groovy-internal trace entries.

  Parameters:

  t - the Throwable whose stack trace to print

• public static Throwable sanitize(Throwable t)

  Remove all apparently groovy-internal trace entries from the exception instance

  This modifies the original instance and returns it, it does not clone

  Parameters:

  t - the Throwable whose stack trace we want to sanitize

  Returns:

  The original Throwable but with a sanitized stack trace

• public static Throwable sanitizeRootCause(Throwable t)

  Get the root cause of an exception and sanitize it for display to the user

  This will MODIFY the stacktrace of the root cause exception object and return it

  Parameters:

  t - a throwable

  Returns:

  The root cause exception instance, with its stace trace modified to filter out groovy runtime classes
