Method Detail

hasAnyCause

public static boolean hasAnyCause(Throwable error,
                                  Predicate<Throwable> causePredicate)

Predicate that returns true if any cause in the exception stack matches the cause predicate.

If a cause matches the predicate, then it return true immediately (skipping other checks).

Parameters:

error - the root error to analyze

causePredicate - the predicate to apply to causes recursively

Returns:

true if the cause predicate returns true for at least one cause in the exception stack

fatalJvmError

public static boolean fatalJvmError(Throwable error)

Checks whether the error has been raised due to a Java Error. Errors should not be ignored. For example, if there is a OutOfMemoryError, retrying may result in consuming more memory and totally crash the JVM or hang the system.

Parameters:

error - the raised error

Returns:

true if the error is fatal JVM error

toString

public static String toString(Throwable e)

Generate a String based on the exception. Unlike default Throwable.toString() method, the Throwable.getCause() may also be included in the generated string (depending of logging configuration). If logger associated to this class is configured to DEBUG or TRACE, then the cause is included.

Parameters:

e - the error to convert to a string

Returns:

the error string

toString

public static String toString(Throwable e,
                              String indentation)

Generate a String based on the exception. Unlike default Throwable.toString() method, the Throwable.getCause() may also be included in the generated string (depending of logging configuration). If logger associated to this class is configured to DEBUG or TRACE, then the cause is included.

Parameters:

e - the error to convert to a string

indentation - the initial indentation

Returns:

the error string
