java.lang.Object

io.debezium.connector.mongodb.transforms.UnwrapFromMongoDbEnvelope<R>

Type Parameters:

R - the subtype of ConnectRecord on which this transformation will operate

All Implemented Interfaces:

Closeable, AutoCloseable, org.apache.kafka.common.Configurable, org.apache.kafka.connect.transforms.Transformation<R>

public class UnwrapFromMongoDbEnvelope<R extends org.apache.kafka.connect.connector.ConnectRecord<R>>
extends Object
