Method Detail

containsType

public static boolean containsType(Throwable throwable,
                   Class<?> type)

This method returns true if the throwable contains a Throwable that matches the specified class or subclass in the exception chain. Subclasses of the specified class do match.

Parameters:

throwable - the throwable to inspect, may be null

type - the type to search for, subclasses match, null returns false

Returns:

the index into the throwable chain, false if no match or null input

getDeepestOccurenceOfType

public static <ET> ET getDeepestOccurenceOfType(Throwable throwable,
                                Class<ET> type)

This method returns the throwable closest to the root cause that matches the specified class or subclass. Any null argument will make the method return null.

Parameters:

throwable - the throwable to inspect, may be null

type - the type to search for, subclasses match, null returns null

Returns:

the throwable that is closest to the root in the throwable chain that matches the type or subclass of that type.

getFullStackTraceWithoutMessages

public static String getFullStackTraceWithoutMessages(Throwable throwable)

Similar to ExceptionUtils.getFullStackTrace(Throwable) but removing the exception and causes messages. This is useful to determine if two exceptions have matching stack traces regardless of the messages which may contain invokation specific data

Parameters:

throwable - the throwable to inspect, may be null

Returns:

the stack trace as a string, with the messages stripped out. Empty string if throwable was null
