Class MapCoderBase<T>

java.lang.Object

com.google.cloud.dataflow.sdk.coders.StandardCoder<T>

com.google.cloud.dataflow.sdk.coders.MapCoderBase<T>

Type Parameters:

T - the type of values being transcoded

All Implemented Interfaces:

Coder<T>, Serializable

Direct Known Subclasses:

MapCoder

public abstract class MapCoderBase<T>
extends StandardCoder<T>

A abstract base class for MapCoder. Works around a Jackson2 bug tickled when building MapCoder directly (as of this writing, Jackson2 walks off the end of an array when it tries to deserialize a class with multiple generic type parameters). This should be removed in favor of a better workaround.
