Method Detail- 
addClassTestpublic 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
 - Parameters:
- test- the testing groovy.lang.Closure
 
 - 
sanitizepublic static Throwable sanitize(Throwable t) Remove all apparently groovy-internal trace entries from the exception instanceThis 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

isApplicationClasspublic static boolean isApplicationClass(String className) 
 - 
extractRootCausepublic 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
 
 - 
sanitizeRootCausepublic static Throwable sanitizeRootCause(Throwable t) Get the root cause of an exception and sanitize it for display to the userThis 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
 
 - 
deepSanitizepublic static Throwable deepSanitize(Throwable t) Sanitize the exception and ALL nested causesThis 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
