io.debezium.connector.oracle.logminer.processor.infinispan.marshalling.TransactionAdapter

@ProtoAdapter(InfinispanTransaction.class)
public class TransactionAdapter
extends Object

An Infinispan ProtoStream adapter for marshalling a InfinispanTransaction instance. This class defines a factory for creating InfinispanTransaction instances when hydrating a transaction record from the protocol buffer datastore as well as field handlers to extract values from a given transaction instance for serializing the instance to a protocol buffer stream.

factory

@ProtoFactory
public InfinispanTransaction factory(String transactionId,
 String scn,
 String changeTime,
 int numberOfEvents,
 String userName,
 Integer redoThreadId)

A ProtoStream factory that creates a InfinispanTransaction instance from field values.

Parameters:

transactionId - the transaction identifier

scn - the starting system change number of the transaction

changeTime - the starting time of the transaction

numberOfEvents - the number of events in the transaction

userName - the user name
