@ProtoAdapter(LobWriteEvent.class)
public class LobWriteEventAdapter
extends LogMinerEventAdapter

An Infinispan ProtoStream adapter to marshall LobWriteEvent instances. This class defines a factory for creating LobWriteEvent instances when hydrating records from the persisted datastore asa well as field handlers to extract values to be marshalled to the protocol buffer stream. The underlying protocol buffer record consists of the following structure:

     message LobWriteEvent {
         // structure of the super type, LogMinerEventAdapter
         string data = 7;
     }

factory

@ProtoFactory
public LobWriteEvent factory(int eventType,
 String scn,
 String tableId,
 String rowId,
 String rsId,
 String changeTime,
 String data,
 int offset,
 int length)

A ProtoStream factory that creates LobWriteEvent instances.

Parameters:

eventType - the event type

scn - the system change number, must not be null

tableId - the fully-qualified table name

rowId - the Oracle row-id the change is associated with

rsId - the Oracle rollback segment identifier

changeTime - the time the change occurred

data - the LOB data

offset - the LOB data offset (0-based)

length - the LOB data length

Returns:

the constructed DmlEvent

getData

@ProtoField(number=7)
public String getData(LobWriteEvent event)

A ProtoStream handler to extract the data field from a LobWriteEvent type.

Parameters:

event - the event instance, must not be null

Returns:

the data to be written for a LOB field, may be null

getOffset

@ProtoField(number=8,
            required=true)
public int getOffset(LobWriteEvent event)

A ProtoStream handler to extract the offset field from a LobWriteEvent type.

Parameters:

event - the event instance, must not be null

Returns:

the offset of the data to be written for a LOB field

getLength

@ProtoField(number=9,
            required=true)
public int getLength(LobWriteEvent event)

A ProtoStream handler to extract the length field from a LobWriteEvent type.

Parameters:

event - the event instance, must not be null

Returns:

the length of the data to be written for a LOB field
