Method Detail

shouldSkip

boolean shouldSkip(Throwable t,
                 int skipCount)
                   throws SkipLimitExceededException

Returns true or false, indicating whether or not processing should continue with the given throwable. Clients may use skipCount<0 to probe for exception types that are skippable, so implementations should be able to handle gracefully the case where skipCount<0. Implementations should avoid throwing any undeclared exceptions.

Parameters:

t - exception encountered while reading

skipCount - currently running count of skips

Returns:

true if processing should continue, false otherwise.

Throws:

SkipLimitExceededException - if a limit is breached

IllegalArgumentException - if the exception is null
