Method Details

findClassInRootChain

public static <T extends Throwable> T findClassInRootChain(Throwable e,
 Class<T> targetClass)

Find a specific exception class in an exception's caused-by chain. Returns null if not found. Be aware, uses class.isInstance (so sub-classes get found).

getClassListFromRootChain

public static <T extends Throwable> List<T> getClassListFromRootChain(Throwable e,
 Class<T> targetClass)

Find a list of exceptions of the given class in an exception's caused-by chain. Returns empty list if none found.

getRootException

public static Throwable getRootException(Exception exception)

Get the root exception in a caused-by-chain.

concatenateMessagesFromChain

public static String concatenateMessagesFromChain(Exception exception)

getTopAndBottomMessages

public static String getTopAndBottomMessages(Exception e)

Get the messages from the top invalid input: '&' bottoms (root) of an exception. If there's no root, just return the top (e.g., parameter)'s message. If they are both found, put ": " between them.

tryIgnore

public static void tryIgnore(UnsafeVoidVoidMethod<?> method)

tryCatch

public static void tryCatch(UnsafeVoidVoidMethod<?> method,
 Consumer<Throwable> catcher)
