Class FailsafeElementCoder<OriginalT,CurrentT>

java.lang.Object

org.apache.beam.sdk.coders.Coder<T>

org.apache.beam.sdk.coders.CustomCoder<FailsafeElement<OriginalT,CurrentT>>

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

Type Parameters:

OriginalT - The type of the original payload to be encoded.

CurrentT - The type of the current payload to be encoded.

All Implemented Interfaces:

java.io.Serializable

public class FailsafeElementCoder<OriginalT,CurrentT>
extends org.apache.beam.sdk.coders.CustomCoder<FailsafeElement<OriginalT,CurrentT>>

The FailsafeElementCoder encodes and decodes FailsafeElement objects.

This coder is necessary until Avro supports parameterized types (AVRO-1571) without requiring to explicitly specifying the schema for the type.
