java.lang.Object

org.apache.beam.examples.complete.datatokenization.utils.FailsafeElement<OriginalT,CurrentT>

@DefaultCoder(value=FailsafeElementCoder.class)
public class FailsafeElement<OriginalT,CurrentT>
extends java.lang.Object

The FailsafeElement class holds the current value and original value of a record within a pipeline. This class allows pipelines to not lose valuable information about an incoming record throughout the processing of that record. The use of this class allows for more robust dead-letter strategies as the original record information is not lost throughout the pipeline and can be output to a dead-letter in the event of a failure during one of the pipelines transforms.
