Method Detail

withCause

public static <T extends Throwable> T withCause(T exception,
                                Throwable cause)

withSuppressed

public static <T extends Throwable> T withSuppressed(T exception,
                                     Throwable... suppressed)

launderedException

public static RuntimeException launderedException(Throwable exception)

launderedException

public static RuntimeException launderedException(String messageForUnexpected,
                                  Throwable exception)

launderedException

public static <T extends Throwable> T launderedException(Class<T> type,
                                         Throwable exception)

launderedException

public static <T extends Throwable> T launderedException(Class<T> type,
                                         String messageForUnexpected,
                                         Throwable exception)

peel

@Deprecated
public static Throwable peel(Throwable exception,
                        Predicate<Throwable> toPeel)

Deprecated. use peel(Throwable, org.neo4j.function.Predicate) instead

Peels off layers of causes. For example: MyFarOuterException cause: MyOuterException cause: MyInnerException cause: MyException and a toPeel predicate returning true for MyFarOuterException and MyOuterException will return MyInnerException. If the predicate peels all exceptions null is returned.

Parameters:

exception - the outer exception to peel to get to an delegate cause.

toPeel - Predicate for deciding what to peel. true means to peel (i.e. remove), whereas the first false means stop and return.

Returns:

the delegate cause of an exception, dictated by the predicate.

peel

public static Throwable peel(Throwable exception,
             org.neo4j.function.Predicate<Throwable> toPeel)

Peels off layers of causes. For example: MyFarOuterException cause: MyOuterException cause: MyInnerException cause: MyException and a toPeel predicate returning true for MyFarOuterException and MyOuterException will return MyInnerException. If the predicate peels all exceptions null is returned.

Parameters:

exception - the outer exception to peel to get to an delegate cause.

toPeel - Predicate for deciding what to peel. true means to peel (i.e. remove), whereas the first false means stop and return.

Returns:

the delegate cause of an exception, dictated by the predicate.

exceptionsOfType

@Deprecated
public static Predicate<Throwable> exceptionsOfType(Class<? extends Throwable>... types)

Deprecated. use Predicates.instanceOfAny(Class[]) instead

Parameters:

types - the exception types to check against

Returns:

a predicate which determines if a Throwable is among the given types

exceptionWithMessage

@Deprecated
public static Predicate<Throwable> exceptionWithMessage(String message)

Deprecated.

rootCause

public static Throwable rootCause(Throwable caughtException)

stringify

public static String stringify(Throwable cause)

stringify

public static String stringify(Thread thread,
               StackTraceElement[] elements)

contains

               String containsMessage,
               Class... anyOfTheseClasses)

contains

contains

@Deprecated
public static boolean contains(Throwable cause,
                          Predicate<Throwable> toLookFor)

Deprecated. use contains(Throwable, org.neo4j.function.Predicate) instead

Parameters:

cause - the cause we have

toLookFor - predicate for the cause we are looking for

Returns:

true if the cause was found

contains

public static boolean contains(Throwable cause,
               org.neo4j.function.Predicate<Throwable> toLookFor)

isAnyOfClasses

@Deprecated
public static Predicate<Throwable> isAnyOfClasses(Class... anyOfTheseClasses)

Deprecated. use Predicates.instanceOfAny(Class[]) instead

Parameters:

anyOfTheseClasses - classes to match against

Returns:

a predicate which yields true if an item is an instance of any of the given classes

combine

public static <E extends Throwable> E combine(E first,
                              E second)
