isConstraintViolationException

public static boolean isConstraintViolationException(Throwable throwable)

Checks if the given exception has its cause in a database constraint violation, that can be a hint of concurrent access (e.g. creating the same user parallel). so maybe a rerun of the causing function helps. This method will check the provided Throwable and the causes up the chain.

Parameters:

throwable - the exception to check

Returns:

true if it is a constraint violation exception and a recall of the function may help

isConstraintViolationExceptionWithoutCause

public static boolean isConstraintViolationExceptionWithoutCause(Throwable th)

Checks if the given exception has is a database constraint violation, that can be a hint of concurrent access (e.g. creating the same user parallel). so maybe a rerun of the causing function helps. Remark: The determination of the violation exception is considering only the given one, not the cause. See isConstraintViolationException(Throwable)

Parameters:

th - the exception to check

Returns:

true if it is a constraint violation exception and a recall of the function may help
