Class SequenceNumberValidator

java.lang.Object

com.amazonaws.services.kinesis.clientlibrary.lib.worker.SequenceNumberValidator

public class SequenceNumberValidator
extends Object

This class provides some methods for validating sequence numbers. It provides a method validateSequenceNumber(String) which validates a sequence number by attempting to get an iterator from Amazon Kinesis for that sequence number. (e.g. Before checkpointing a client provided sequence number in RecordProcessorCheckpointer.checkpoint(String) to prevent invalid sequence numbers from being checkpointed, which could prevent another shard consumer instance from processing the shard later on). This class also provides a utility function isDigits(String) which is used to check whether a string is all digits
