Class 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.

        @ProtoFactory
public InfinispanTransaction factory​(String transactionId,
                                     String scn,
                                     String changeTime,
                                     int numberOfEvents,
                                     String userName)
        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
        Returns:
        the constructed Transaction instance

        @ProtoField(number=2,
            required=true)
public String getScn​(InfinispanTransaction transaction)
        A ProtoStream handler to extract the startScn field from the InfinispanTransaction.
        Parameters:
        transaction - the transaction instance, must not be null
        Returns:
        the starting system change number, never null

      • getChangeTime

        @ProtoField(number=3,
            required=true)
public String getChangeTime​(InfinispanTransaction transaction)

        @ProtoField(number=4,
            defaultValue="0")
public int getNumberOfEvents​(InfinispanTransaction transaction)
        A ProtoStream handler to extract the eventIds field from the InfinispanTransaction.
        Parameters:
        transaction - the transaction instance, must not be null
        Returns:
        the number of events in the transaction
