Method Detail

addClassTest

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.

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

deepSanitize

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

extractRootCause

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

isApplicationClass

public static boolean isApplicationClass(String className)

printSanitizedStackTrace

public static void printSanitizedStackTrace(Throwable t, PrintWriter p)

printSanitizedStackTrace

public static void printSanitizedStackTrace(Throwable t)

sanitize

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

sanitizeRootCause

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
